Limited Warranty Statement

1 Matrox

("Matrox") having its head office at 1055 St-Regis Blvd., Dorval, Quebec Canada tel: (514) 822-6000 warrants that the Matrox hardware products (the "Matrox Product") will be free from defects in materials and workmanship under normal use for a period of three (3) years from the date of purchase by the original customer ("Customer" or "You") who provides adequate proof of purchase and payment (for example, a copy of your sales receipt or purchase invoice). The warranties provided by Matrox in this Matrox limited warranty statement apply only to Matrox Products that the Customer purchases for use, and not for resale. This warranty applies only to the original Customer and is non-transferable. MATROX DOES NOT WARRANT THAT THE OPERATION OF THE MATROX PRODUCT WILL BE UNINTERRUPTED OR ERROR-FREE, THAT DEFECTS IN THE MATROX PRODUCT WILL BE CORRECTED, OR THAT THE MATROX PRODUCT WILL MEET THE CUSTOMER'S REQUIREMENTS OR PERFORM WITH ANY HARDWARE OR SOFTWARE PROVIDED BY THIRD PARTIES. Conditions and limitations of Matrox's warranty are stated below.

2 Matrox's limited warranty applies only to the Matrox Product entirely manufactured by or for Matrox. The limited

warranty does not apply to any non-Matrox hardware products or any software, even if packaged or sold with the Matrox Product. Manufacturers, suppliers or publishers other than Matrox may provide their own warranties to the Customer, but Matrox, insofar as permitted by law, provides their products "as is." Software provided by Matrox is not covered under this limited warranty (please refer to the licensing agreement accompanying the software for details of the terms applicable to such).

3 Matrox's limited warranty covers only those defects which arise as a result of normal use of the Matrox Product

and does not apply to any damage which arises from:

a improper or inadequate maintenance;

b incompatibilities due to the Customer's hardware or software applications, including non-Matrox products,

with or in which the Matrox Product interfaces;

c Matrox Product of a special or custom-made nature;

d unauthorized modification or misuse, including physical damage to the Matrox Product caused by the

Customer or due to transportation of the product;

e improper installation, abuse, misapplication or negligence;

f failure to follow instructions relating to Matrox Product's use;

g operation outside the Matrox Product's environmental specifications;

h improper site preparation or maintenance;

i software;

j service performed by anyone who is not a representative of Matrox;

k other causes that do not relate to a Matrox Product defect;

l defects or damage suffered as a result of force majeure (including theft);

m defects or damage suffered as a result of normal wear and tear or otherwise due to the normal aging of the

Matrox Product, and/or

n stolen goods.

The warranty is voided by removal or alteration of identification labels on the Matrox Product or its parts.

4 In the event of a defect in a Matrox Product during the applicable warranty period, Matrox shall at its sole option,

either i) repair the defect using new or refurbished parts and return the repaired Matrox Product within a reasonable delay; or ii) replace the Matrox Product with a Matrox Product that is new or which has been manufactured from new or serviceable used parts and is at least functionally equivalent to the original Matrox Product and send such replacement Matrox Product within a reasonable delay.

Matrox is Matrox Electronic Systems Ltd, Matrox Graphics Inc. or Matrox Europe Limited. Head office at 1055 St-Regis Blvd. Dorval, Quebec, Canada H9P 2T4 Telephone (514) 822-6000.

Matrox Limited Warranty

5 A replacement Matrox Product or part assumes the remaining warranty of the original Matrox Product.

When a Matrox Product or part is replaced, any replacement item becomes the Customer's property and the replaced item becomes Matrox's property.

6 This warranty is valid in any country where Matrox Products are distributed by Matrox and/or its authorized

resellers, dealers or distributors.

7 This limited warranty gives the Customer specific legal rights. The Customer may also have other

rights which vary from state to state in the United States, from province to province in Canada, and from country to country elsewhere in the world.

8 For Australian Consumers: The rights described in this warranty are in addition to the statutory rights to

which You may be entitled under the Competition and Consumer Act 2010 and other applicable Australian consumer protection laws and regulations. Our Matrox Products come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure. Goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.

Introducing Matrox VS4

This chapter lists the Matrox VS4 system requirements, and describes the VS4 documentation.

Welcome to Matrox VS4

Matrox VS4 is a quad HD-SDI card that lets you record up to four channels simultaneously using the VS4Recorder Pro stand-alone recording application, and using Telestream Wirecast or StudioCoast vMix, you can create video streaming productions as well as record your source feeds.

Matrox VS4 lets you take advantage of professional broadcast video and audio sources. Using a single PCIe slot, Matrox VS4 provides up to four independent HD-SDI inputs with up to eight embedded audio channels per source. Because all inputs on Matrox VS4 are independent, you can use HD and SD sources in the same production. Full-size BNC connectors connect directly to your sources.

You can record your input sources as .avi files, .mov files, or .mp4 files, and then use your favorite editing application, such as Adobe Premiere Pro, to natively edit your material. You can use the following codecs for each file:

• For .avi files, you can use the MPEG-2 I-frame codec at up to 300 Mb/s (HD) or 50 Mb/s (SD).

• For .mov files, you can use a Matrox DV codec or the H.264 codec.

• For .mp4 files, you can use the H.264 codec.

Up to two VS4 cards are supported per system. In a two-card system, all eight VS4 inputs are available for streaming in Telestream Wirecast, and recording is supported on the four inputs of the primary VS4 (see “Selecting your primary

VS4 card” on page 93).

Matrox VS4 system requirements

Matrox VS4 requires a computer system with the following minimum requirements:

• Microsoft Windows 7 (64-bit) with Service Pack 1.

Last-minute information

• Any important information that wasn’t available for inclusion in this guide by publication time is provided to you in the Matrox VS4 Release Notes.

Chapter 1, Introducing Matrox VS4

Installing Matrox VS4

Hardware and Software

This chapter describes how to install your Matrox VS4 hardware and software.

Before installing your Matrox hardware

Read the following information carefully before attempting to install the Matrox VS4 card.

¦NoteUnless otherwise specified, references to the VS4 card in this guide

apply to both VS4 and VS4 Pro cards.

Start with a functioning system

Before attempting any Matrox VS4 installation, you should have a computer with a supported Windows operating system fully installed and functioning smoothly. This will avoid potential problems later on.

Avoid costly damage

Static electricity from your body can damage your Matrox VS4 card or your computer. Although you may not notice it, static electricity is generated every time you move. It’s often too small to cause a spark, but it can still cause damage to sensitive electronic components or at least reduce their lifespan.

To avoid damage, please observe the following precautions:

• Do not remove your Matrox VS4 card from its anti-static bag until you’re ready to install it. Before removing the card, place the package within easy reach of the area where you intend to perform the installation.

• You should avoid touching the chips and other components on the circuit board. Try to handle the card by its edges.

• Try to work in an area where the relative humidity is at least 50%.

• Do not wear wool or synthetic clothing. These fabrics tend to generate more static electricity than cotton, which is best for this kind of work.

• Turn off the power switches on your computer and its connected components.

Once you’ve opened your computer, drain static electricity from your body by touching a bare metal surface on your computer chassis before you install or remove any parts of your system. If you have a grounding wrist strap, use it while handling and installing any components in your computer.

Installing your Matrox VS4 card

The Matrox VS4 card is a three-quarter length PCIe card designed to operate in your computer’s x8 or greater PCIe slot (x8 electrical recommended for optimal performance). You can install up to two VS4 cards in the same system.

For detailed instructions on how to perform the following steps, refer to your computer’s documentation.

Chapter 2, Installing Matrox VS4 Hardware and Software

1 Shut down the computer, unplug the power cord and all the cables from the

unit, and open the computer’s chassis.

2 Insert the Matrox VS4 card in an available PCIe x8 (electrical) slot in the

computer, and secure the card into place.

²Caution To avoid overheating issues, don’t install the Matrox VS4 card

close to another card that generates heat, such as a display card.

3 Close the computer chassis, and reconnect the power cord and all the cables

to the unit.

Installing Matrox VS4 software

Matrox Mtx.utils Setup installs the VS4 device drivers and VS4 software. If you plan on using VS4 with a Matrox Convert DVI product, Matrox Mtx.utils Setup gives you the option of installing the Convert DVI software as well. If you want to use StudioCoast vMix with VS4, you must choose to install the Matrox A/V DirectShow Filters. For more information on using VS4 with StudioCoast vMix, see Chapter 6, “Using Matrox VS4 with StudioCoast vMix,” on page 79.

Before installing Matrox Mtx.utils, make sure that all supported third-party applications that you want to use with VS4, such as Telestream Wirecast, are installed. You can install Matrox Mtx.utils on a computer with or without the Matrox VS4 card installed.

To download and install the latest version of Matrox Mtx.utils, visit the Support section of our website at www.matrox.com/video/support. You can also contact your Matrox representative for the latest software.

Updating your VS4 firmware

When you install Mtx.utils while your VS4 card is installed in your computer, the Mtx.utils Setup program automatically verifies the firmware on your VS4 card and updates it if required. If you install Mtx.utils on a computer without the VS4 card, the next time you start your computer with your VS4 card installed, Mtx.utils Setup will update your VS4 firmware if needed.

²Caution Do not power off your computer, or interrupt the firmware update

during the update process. Doing so may damage your VS4 card.

Important note about sleep and hibernation modes

Your system’s sleep and hibernation modes are not supported by the Matrox Mtx.utils software. To avoid stability issues, disable sleep and hibernation modes on your system after installing Matrox Mtx.utils.

Installing Matrox VS4 software

Removing your Matrox VS4 software

Perform the following steps to remove the VS4 software from your computer. When uninstalling the VS4 software, your current VS4 settings are kept for future VS4 software installations.

Overview

VS4Recorder Pro is a versatile stand-alone application that lets you frame accurately record four live audio/video feeds using a VS4 card. It’s ideal for multi-camera productions, providing HD/SD recordings that can be easily repurposed and archived, while simultaneously offering a complete multi-viewer experience. VS4Recorder Pro offers two record modes and a multiple-VS4 networking workflow to suit your needs:

• Multi-Cam mode provides synchronized frame accurate captures. Using

VS4Recorder Pro in Multi-Cam mode allows you to record multiple angles of a single event, easily started and stopped using a single record button.

• Independent mode is for quickly recording content for the archiving or

repurposing of video assets. Independent mode lets you monitor and control the recording of up to four sources independently using dedicated record buttons.

• VS4Control is for synchronized, frame-accurate recordings of an unlimited

number of video sources connected to multiple, networked VS4 machines, organized in a master-slave configuration.

¡ Important For all recording sessions, Input 1 must be connected to a valid

source.

To select a record mode, click the Record Mode record using VS4Control, select the

Multi-Cam mode

Allows you to start and stop the recording of up to four sources at the same time using a single record button. This mode is ideal for recording multi-camera live events. Recording in this mode initiates a session timer whereby each source recording shares the same event timecode. The Control bar timer displays frames only when all selected sources are the same frame rate, however, the embedded timecode in each recorded file always contains frames.

You can start and stop individual source recordings separately during a recording session without interrupting the event run-time. In addition, the current duration of each recording is displayed in the corresponding source window popover.

Independent mode

Allows you to start and stop the recording of up to four sources independently using dedicated record buttons. Each source recording is its own recording session. This mode is ideal for quickly recording content for the archiving or repurposing of video assets.

Rather than sharing a unified session timecode, the timecode for each source recording is based on its own duration, which is displayed in the corresponding source window popover. If you choose to embed the VS4Recorder Pro timecode in your video files, the timecode values are taken from the timer in the respective source window popovers.

Disk space indicator

VS4Recorder Pro provides a disk space indicator in each of the source windows (see “Source window popover” on page 20). The indicator provides a visual representation of the available disk space on the source’s specified record path disk, and displays the approximate remaining record time before the disk is full. The remaining record time is calculated based on the source’s video format and current record settings.

For sources that are set to record to the same disk, if none of the corresponding sources are currently recording, the remaining record time appears for all sources, and is calculated based on all sources. If one or more of the corresponding sources are currently recording, the remaining record time is calculated and shown only for the sources that are recording.

Record status

VS4Recorder Pro includes a Record Status LED and a Dropped-Frame indicator so that you can quickly view the status of your source recordings.

Windows Explorer at the specified source record path to view the recorded video and audio files, and the record log file. For information on the specific location of the record log file, see “Record log file". In Multi-Cam mode, if different record paths were specified for the source recordings, a separate window will open for each record path. If dropped/skipped frames were detected at any time during a recording session, the Dropped-Frame icon appears within the Record Path button. The button disappears when a new recording session is initiated.

Record log file

The record log file provides a breakdown of recording events per source, such as dropped and black frames, file splitting, capture duration (when applicable), and the timecode of when the events occurred. The recording session determines when the record file is generated and where the file is saved.

• Multi-Cam mode One record log file is created per recording session, and

is generated once the entire recording session is stopped. The record log file includes the breakdown of events for all sources that were recorded during the recording session. The location of the record log file depends on the record path selected:

$ If the Use same path option is selected in the VS4Recorder Pro settings,

the record log file is located in the same session folder that contains all the video and audio files for the recording session.

$ If the Use same path option is cleared, a different session folder is

created for each source recording within a recording session. In this case, the record log file is located in the session folder corresponding to Input 1.

Chapter 4, Using the VS4Recorder Pro Application

• Independent mode A separate record log file is generated after each

source recording, and is saved in the same session folder that contains the video and audio files for the source recording.

• VS4Control One record log file is created per machine, and they are generated once the entire recording session is stopped. The record log files include the breakdown of events for all sources that were recorded from their respective machines during the recording session. The location of the record log files depend on the record path selected:

$ If the Use same path option is selected, the record log files are located in

the same machine-specific folder that contains all the video and audio files of the inputs of that machine.

$ If the Use same path option is cleared, different folders are created for

each source recording on a machine. In this case, the record log files are located in the session folder corresponding to Input 1 of each machine.

Event markers

You can add event markers to your video to mark an event of interest, making that moment easy to locate. The event markers you add in VS4Recorder Pro will be visible when you add the video to a timeline for editing in Adobe Premiere Pro CC or CS6.

How event markers work

To create event markers, the VS4Recorder Pro application must be the active window on your computer, and you must be recording at least one file. The event markers are written to all captured video files.

For example, you may want to mark when a team scores in a sporting event, or a specific crowd interaction at a concert. You can add event markers in Multi-Cam and Independent modes, or when using VS4Control.

¦NoteEvent markers can be added to .mov, .avi, and .mp4 video files, but not

audio files.

Adding event markers to your video recording

1 Start your recording session.

2 Press asterisk (*) from any machine, Master or slave, when you see an event

of interest (the status LED will briefly turn blue).

3 Add more markers as needed.

You can now see where these events occurred in your video editing timeline in Adobe Premiere Pro.

• To specify a separate record path for each source, under clear the

Use same path option, and then click the folder icon for each

Session and File,

source to browse to the desired destination. In this case, a separate session folder is created for each source recording.

Session folders

VS4Recorder Pro organizes your source recording files into session folders. How session folders are created and the naming of the session folders depends on the recording configuration:

• Multi-Cam mode and when using VS4Control If the

Use same path

option is selected in the VS4Recorder Pro settings, a single session folder is created for the entire recording session, wherein the video and audio files for all source recordings are saved.

Settings

The folder name is in the following format:

SessionName-YYYY-MM-DD HHMMSS

If the

Use same path option is cleared in the VS4Recorder Pro settings, a

separate session folder is created for each of the source recordings in the source’s specified record path. The folders are differentiated by the source input number in the following format:

SessionName-YYYY-MM-DD HHMMSS_input

• Independent mode A separate session folder is created for each of the

source recordings in the source’s specified record path. The folders are differentiated by the source input number in the following format:

YYYY-MM-DD HHMMSS_input

Files and file naming

Depending on the selected video codec, the recorded video file format will be either .avi,.mov, or .mp4. If you choose to include audio with your recording, the first two audio channels from the input source are embedded in the video file, and separate PCM (.wav) or AAC (.aac) audio files are created based on the specified audio settings.

¦NoteSeparate .wav and .aac files follow path and naming convention of the

corresponding source video file.

Specifying the save file name

Under

Session and File, in the Filename box for each source, specify the save

file name that you want for the source’s recorded video/audio files. For information on the file naming convention, see “File naming convention" and

“How files are named".

¦NoteYou can set VS4Recorder Pro to display the source filename in the

corresponding source window (see “Label and filename overlay” on page 57).

¥Tip Even if a source is currently recording, you can set up the next recording

for that source by changing the source

Filename and Label in the Settings

window. The current filename and label settings apply to the source’s next recording. Once a source recording has started, you can change these settings without affecting the current recording.

Chapter 4, Using the VS4Recorder Pro Application

File naming convention

As captured video files are created and saved, a naming convention is applied to make them easy to locate and identify. The naming convention follows a specific order of identifiers; however, the saved video file path changes somewhat depending on your settings. For example, the

Include in Filename drop-down

menu options, the use of file splitting, or choosing to record in Stereo or Mono all have an effect.

How files are named

The save file name applies to both the video and audio files that are recorded for a source; however, the file naming convention differs based on the recording. The starting and stopping of the recording session or of a single input, creates new incrementing indexes following the input number. File splitting creates a 3-digit index before the file extension.

You can have more than one recording for a given source during the same recording session. In this case, the files are differentiated by a recording number (index). This occurs when:

• You disable a source that is currently recording, and then re-enable the same source during the same recording session. This results in a different file for each sequence.

• If you experience a loss of signal, causing a disconnection, the recording will continue in the original video file, with black video recorded between connections.

• You enable file splitting, which splits the captured video files at set intervals. Every time the split time limit elapses, a new file with a unique file name is created. For more information, see “Automatic file splitting” on page 38.

Audio files

If you choose to include audio with your recording (see “Audio settings” on page

45), the first two audio channels from the input source are embedded in the video

file, and separate audio files are created as specified in the VS4Recorder Pro settings. The separate audio files are named the same as the corresponding source video file, except that they also include the audio channel type (mono or stereo) and an incremental suffix using the following convention:

filename_input_recordingnumber_channeltypesuffix or

filename_channeltypesuffix

¦NoteWhen recording eight audio channels, if you choose to create mono files

instead of stereo files, eight files will be created instead of four, and the files will be named Record_Mono1, Record_Mono2, Record_Mono3, and so on.

Settings

File naming based on recording session

As captured video files are created and saved, a naming convention is applied. Although the naming convention follows a specific order, the file naming convention differs based on the recording configuration:

• Multi-Cam mode

\sessionname_date_time\filename_sessionname_machinename _InputIndex _index.fileextension

• Independent mode

\date_time_input\filename_machinename.fileextension

• VS4Control:

$ Master machine:

\sessionname_date_time\filename_sessionname_machinename_mx _InputIndex_index.fileextension

$ Slave machine:

\sessionname_date_time\filename_sessionname_machinename_mx_sx _InputIndex_index.fileextension

Remarks

• mx: Masterindex

• sx: Slaveindex

• InputIndex: The SDI input on the VS4

The index is incremented when an input is stopped and/or started during a capture session.

Labels

In addition to filenames, you can also give a descriptive label to each source. For example, you can label source 1 as Camera 1. VS4Recorder Pro can be set to display the source labels in the respective source windows (see “Label and

filename overlay” on page 57), and the label information is embedded in every

recorded video file as XMP metadata for use in Adobe Premiere Pro CC and CS6 (see “Viewing VS4Recorder Pro metadata in Adobe Premiere Pro” on page 60).

¥Tip Even if a source is currently recording, you can set up the next recording

for that source by changing the source window. The current filename and label settings apply to the source’s next recording. Once a source recording has started, you can change these settings without affecting the current recording.

Chapter 4, Using the VS4Recorder Pro Application

Label and Filename in the Settings

Under Session and File, specify a descriptive label in the Label box for each source.

Capture duration

You can set a capture duration limit that stops a recording session after a specific time limit. Once the limit is reached, the recording session will stop automatically.

How capture duration works

A helpful feature of setting a capture duration is the option of unattended recording. The minimum settable duration is one (1) minute. This setting applies to all inputs. The timer starts once you begin to record. If you do not wish to limit your recording time, you must clear the

¥Tip When capturing .mp4 files, enabling Capture duration creates streamable

files.

Capture duration feature operates in minute increments, and the

Capture duration option button.

Capture duration functions differently depending on the recording

configuration:

• Multi-Cam mode:

$ One timer is set for all inputs.

$ When you stop the recording session, the timer resets.

$ When you connect another feed (input) while capturing, the timer will

continue (no reset).

$ If an input is disabled, and then re-enabled while capturing, the timer will

continue (no reset).

• Independent mode:

$ The timer operates independently for each input.

$ When you stop capturing on an input, it resets the timer of that particular

input.

$ When you connect another feed (input) while capturing, the timer will

continue (no reset).

Settings

• VS4Control:

$ The time limit is set and controlled through the settings of the Master only

(the slave settings are ignored).

$ When you stop the Master, the recording stops and the timer resets.

$ The Capture duration option will not be available for slave units (see

“VS4Control” on page 51).

Setting a capture duration

Setting a capture duration means stopping your recording session at an exact time, which can be convenient when your sources are at a distance. Before beginning your recording session:

1 Select Capture duration in the Session and File section of the

VS4Recorder Pro settings.

2 Enter the time limit in minutes.

3 Set your other preferences in the Settings window.

4 Start recording.

The (internal) timer on your capture duration limit begins, and will stop the session at the designated time.

Automatic file splitting

You can split your recording at set intervals, creating separate files. Every time the split time limit elapses, a new file with a unique file name is automatically created.

How file splitting works

Operating like an auto save, the

Split file every option saves separate video and

audio files to a folder you specify, that you can start editing as soon as each one is created. File splitting causes no loss of video frames between files and .mov, .avi, and .mp4 files are supported.

By splitting video files, you can also protect your files, ensuring that only the current file being captured would be affected by a sudden power failure or computer crash. The file splitting feature operates in minute increments, and the minimum settable duration is one (1) minute. This setting applies to all inputs. The timer starts once you begin to record. If you do not wish to create split files, you must clear the

Split file every option button.

¥Tip When capturing .mp4 files, file splitting creates streamable files.

File splitting functions differently depending on the recording configuration:

Chapter 4, Using the VS4Recorder Pro Application

• Multi-Cam mode:

$ One split timer is set for all inputs.

$ When you stop the recording session, the split timer resets.

$ When you connect an input while capturing, that input will split at the

scheduled interval without resetting.

$ When you disconnect and reconnect an input while capturing, that input

will split at the scheduled interval without resetting.

• Independent mode:

$ The split timer operates independently for each of the inputs.

$ When you stop capturing on an input, it resets the split timer of that

particular input.

$ When you connect an input while capturing, that input will split at the

scheduled interval without resetting.

• VS4Control:

$ The split timer operates independently for each machine, so you must set

the interval on each individual machine (in order for all machines to start when the Master starts the recording session).

$ All split timers start when the Master starts.

$ When you stop recording from the Master, it resets the split timer on all

machines (see “VS4Control” on page 51).

$ When you connect an input while capturing, that input will split at the

scheduled interval without resetting.

$ When you disconnect and reconnect an input while capturing, that input

will split at the scheduled interval without resetting.

Splitting audio and video files

File splitting lets you start editing (with a suitable application) before the recording session has ended. Before beginning your recording session:

1 Select Split file every in the Session and File section of the VS4Recorder

Pro settings.

2 Enter the time in minutes.

3 Set your other preferences in the Settings window.

4 Start recording.

The (internal) file splitting timer begins, and will save a file at each designated interval.

Settings

Split file naming

An automatic naming convention is applied to split video files. An index will be appended to the split file (see “File naming convention” on page 35). However, if a file name is changed during a capture, the next split file will not get the new file name (as its base file name). The new file name is only applied whenever a recording session (Independent, Multi-Cam or VS4Control) is stopped and then restarted after the change is made, or when reconnecting an input (during a capture) with a different resolution.

Splitting WAV audio files

Depending on your audio settings, when you record separate .wav files along with your video, the .wav files have a maximum size of 4 GB, which also makes for a maximum time duration. If you wish to capture a lengthy separate .wav file, file splitting will be required, to make .wav files that will respect the size limitation (see “WAV files” on page 46).

Splitting AAC audio files

You can capture AAC codec data when recording:

• H.264 .mp4 or H.264 .mov

• AAC files as separate audio files

¡ Important When file splitting is enabled, AAC is not available for separate

audio files.

Video codec

Select specific video codecs for HD and SD sources. The selected codec will be used for all subsequent HD and SD recordings. For more information, see

“Advanced settings” on page 44.

If you choose to include audio with your recording, the first two audio channels from the input source are embedded in the video file as PCM audio, or AAC audio when using the H.264 codec, and separate audio files are created as specified in the VS4Recorder Pro setting.

Remarks

• If recording files using an H.264 codec, the resulting .mov or .mp4 file will include either stereo or mono embedded AAC audio, depending on your audio settings.

• If recording files using the MPEG-2 I-frame codec, the resulting .avi file will include embedded stereo PCM audio.

• If recording files using a DV codec, the resulting .mov file will include either stereo or mono embedded PCM audio, depending on your audio settings.

For more information, see “Audio settings” on page 45.

Chapter 4, Using the VS4Recorder Pro Application

¦NoteWhen selecting a video codec, make sure that the codec is supported in

your editing application. Working with MPEG-2 I-frame .avi files requires a system with the appropriate Matrox codec installed. For details, see “Working

with editing applications” on page 60.

HD settings

Under

Video Codec, from the HD Settings menu, select the video codec that

will be used for all subsequent HD recordings:

• H.264 (MOV, MP4) Creates either an H.264 .mov or .mp4 file (selectable)

with embedded stereo or mono AAC audio. If this option is selected, you can:

$ Set the Bit Rate Encoding to either Constant (CBR) or Variable (VBR).

$ Set the GOP Size to a seconds value of 0.5, 1, 2 or 5.

$ Set the Target Data Rate to a value in Mb/s.

$ Set the Max Data Rate to a value in Mb/s

$ Click to set the GOP size, target or max data rate to the default HD

value.

$ Set the AAC Data Rate, in the Audio Codec section, to a value in Kb/s.

•

MPEG-2 I-frame HD (AVI) Creates an MPEG-2 I-frame .avi file with

embedded stereo PCM audio. If this option is selected, specify the

$ You can set the Data Rate to any value between 50 Mb/s and 300 Mb/s.

$ Click to set the data rate to the default HD value.

¦NoteMPEG-2 I-frame .avi files are not supported in Avid editing

applications on Windows systems.

•

DVCPRO HD (MOV) Creates a DVCPRO HD .mov file with embedded

stereo or mono PCM audio. DVCPRO HD does not support 1080p @ 24 fps input sources for recording. If a 1080p @ 24 fps input source is detected, the MPEG-2 I-frame codec will be used instead.

SD settings

Under

Video Codec, from the SD Settings menu, select the video codec that

will be used for all subsequent SD recordings:

Settings

• MPEG-2 I-frame (AVI) Creates an MPEG-2 I-frame .avi file with

•

DVCPRO (MOV) and DVCPRO50 (MOV) Creates a DVCPRO or

DVCPRO50 .mov file with embedded stereo or mono PCM audio.

¦NoteYou can make SD recordings using the H.264 codec (see “HD settings")

H.264 video capture

The VS4Recorder Pro offers real-time video capture to H.264 using Intel’s Quick Sync Video (QSV) technology (available with i7 processors).

¦NoteIf QSV technology is not present or not enabled, the H.264 codec will

not be available in the

If the on-board Intel GPU is used as the main display and for encoding to H.264, it can result in dropped frames and/or a sluggish UI, because the same GPU is being used to perform two intensive tasks (encoding four streams to H.264 and displaying four live windows). For that reason, it is recommended to use a separate GPU as the main display for a better experience.

Settings dialog.

Long captures in H.264

If you choose to capture H.264 (.mp4 or H.264 .mov) files with a set capture duration of over 480 minutes (8 hours), the .wav audio format will be automatically selected and file splitting will automatically create a new video file every 480 minutes. You can choose your own split file interval (starting at 1 minute). This restriction does not exist for .avi or DV and DVCPROHD .mov files; however, depending on the split value you set, be sure to select the right settings for the .wav files (see “WAV files” on page 46).

¦NoteStreamable files are created when capturing .mp4 files with either

automatic file splitting or capture duration enabled.

QSV display setup

To setup QSV on a desktop PC with Intel

i7 processors, and an additional NVIDIA or AMD PCIe graphics card installed (without having to connect an additional monitor), you should:

Chapter 4, Using the VS4Recorder Pro Application

1 Confirm that your CPU supports QSV technology.

2 Enable your Intel graphics card to work with Intel integrated graphics

(iGPU) in BIOS and save changes.

3 Install the latest Intel graphics drivers (strongly recommended). QSV

acceleration may not be available or not work with old graphics drivers.

4 Go to your Screen Resolution settings, and click Detect to expose inactive

video outputs.

Apply, then Keep changes, and then

Video Codec section.

H.264 (MP4) and H.264 (MOV) should be available.

Advanced settings

Depending on your video codec selection, different advanced options are available to suit your project requirements. The video codecs have applicable encoding types. Depending on the codec selected, you can set the encoding to either Constant or Variable:

• Constant bit rate (CBR) Video is compressed at your specified target data

rate, which is useful when you need to limit or predict the size of your video file. However, if your video is very complex (such as scenes with many colors, sharp edges, or transitions), you'll need to specify a high target data rate to avoid having frames of blocky video in your file.

• Variable bit rate (VBR) Video is compressed at varying data rates based

on the complexity of the video and your specified maximum data rate. The applicable codecs analyze and encode each frame to deliver the highest possible quality at your target data rate.

Chapter 4, Using the VS4Recorder Pro Application

Only the Target Data Rate will be available if you selected Constant bit rate (CBR). If you select Variable bit rate (VBR), three other settable controls will be available: The GOP size, the target and maximum data rates for the video compression.

Audio settings

You can choose whether or not to record audio along with your video. The following sections detail the audio settings for recording.

Enabling audio and selecting audio channels

If you enable a source’s audio for recording, the first two audio channels from the input source are embedded in the video file as PCM or AAC audio, and separate audio files are also created. The embedded audio in the video file and separate audio files can be either stereo or mono, depending on your settings.

If you are using the MPEG-2 I-frame video codec, the embedded PCM audio in the .avi video file is always stereo. You can choose to record the first two, four, six, or eight audio channels as separate stereo or mono audio files. If you disable a source’s audio for recording, audio will not be embedded in the source’s video file, and separate audio files will not be created for the source recording.

To enable source audio for recording, under source’s corresponding

Audio box, and then select the number of audio channels

that you want to record as separate audio files ( audio for recording, under

Audio box. Source audio is automatically enabled for recording when a source is

¦NoteA source’s audio channel setting also determines the number of audio

channels that are visible in the source’s VU meter. If source audio is disabled, the source’s VU meter will not appear. See “VU meters” on page 50 for more information.

Settings

File type

Under

Audio Codec, select the type of separate audio files that you want to

create:

•

WAV Records PCM audio to separate .wav files.

•

AAC Records AAC audio to separate .aac files.

WAV files

The WAV audio format has a restriction; namely, .wav files have a maximum size of 4 GB. This means that depending on your audio settings, when you record separate .wav files along with your video, the .wav files are limited to a maximum duration.

If you wish to capture a lengthy separate .wav file, use file splitting to make several .wav files that will respect the size limitation, while still being able to capture the full duration of your recording (see “Automatic file splitting” on page

38).

¦NoteThis restriction does not apply to separate .aac audio files or to the

embedded audio in the video file, which can last as long as the associated video.

The following table lists the approximate maximum duration for a separate .wav audio file based on the audio settings:

Audio Channel Type Audio Bit Depth

16-bit 12 hours

Mono

Stereo

24-bit 6 hours

16-bit 6 hours

24-bit 3 hours

AAC files

You can capture AAC codec data when recording:

• H.264 .mp4 or H.264 .mov

• AAC files as separate audio files

When file splitting is enabled, AAC is not available for separate audio files.

Chapter 4, Using the VS4Recorder Pro Application

Approximate

Maximum Duration

Bit depth

Select the bit depth that you want for the two channels of embedded PCM audio in your video file, and the separate audio files that are recorded.

Channel type

Select the channel type that you want for all the separate audio files that are recorded. If recording to an .mov video file (see “Video codec” on page 40), this setting also applies to the audio that is embedded in the recorded video file.

•

Mono Creates a separate .wav or .aac audio file for every selected

channel. For example, if four audio channels are selected, four mono audio files will be created. The embedded audio in an .mov file will also be mono (not supported for embedded audio in an .avi file, which is always stereo).

•

Stereo Creates a separate .wav or .aac audio file for each audio pair

selected. For example, if four audio channels are selected, two stereo audio files will be created. The embedded audio in an .avi, or .mov file will also be stereo.

Data rate

If AAC is selected as the audio file type (see “File type” on page 46), specify the bit rate (in Kb/s) that you want for all the separate audio files that are recorded. You can set the data rate to any value between 32 Kb/s and 512 Kb/s.

¦NoteThis setting also affects the enbedded audio when capturing video in

H.264.

Timecode settings

VS4Recorder Pro includes timecode metadata in every recorded video file for easy synchronization in Adobe Premiere Pro CC and CS6. The starting timecode in a video file corresponds to the timecode at the moment when the source recording was started. You can choose to embed the timecode that is present in the SDI source, or the VS4Recorder Pro session timecode. Select to embed the current time in the video files (see “System Time” on page 49).

¦NotePreviously, embedded timecode present in any source would be used for

the corresponding input. Now, this is only possible when recording in Independent mode; otherwise, it will be taken from Input 1 only.

System Time

Settings

To set the embedded timecode option, under Timecode, select one of the following:

• SDI Embedded The starting timecode value for the recorded video file is

based on the timecode present in the SDI video signal.

• Session The starting timecode can be set to a valid value.

• System Time The timecode is taken from the local computer configuring

the VS4Recorder Pro settings.

Using a timecode from an SDI embedded video signal

If you choose to embed the timecode that is present in the SDI source, select the SDI embedded option button in the Timecode section of the VS4Recorder Pro

Settings dialog. SDI embedded timecode use differs depending on the recording

configuration:

• Multi-Cam mode There must be a signal coming in from a source

connected to Input 1 when you start the recording session.

$ If another input is recording at a different frame rate than Input 1, then the

timecode on that input’s captured file(s) will be that of its own embedded timecode, different from the other inputs. If that input does not have an embedded timecode, then the Session timecode will be written to the video file(s) instead.

$ If an input starts capturing only after the recording session has begun, it is

the SDI timecode from the start of the recording session that is written to the video, plus the offset (the input's staggered start time).

• Independent mode:

$ The SDI embedded timecode of each individual input will be used.

$ If no SDI timecode is present, the recording Session timecode will be

written instead.

• VS4Control The same applies as it does in Multi-Cam mode. The

timecode is taken from Input 1 of the Master machine.

¡ Important Ensure that all cameras (sources) are genlocked to the same source

(Input 1) and that it is a valid source. Without it, frame-accuracy cannot be achieved.

Session timecode

You can tailor your session timecode to your needs with the starting the timecode at a value of your choosing. If you choose to embed the

Session timecode in your recorded video files, note the following:

Chapter 4, Using the VS4Recorder Pro Application

Session option,

• Multi-Cam mode The starting timecode value is based on the session

timer on the Control bar (see “Control bar” on page 17).

• Independent mode The starting timecode value is based on the timer in

the respective source window popovers (see “Source window popover” on

page 20).

• VS4Control The starting timecode value is based on the session timer on

the Control bar of the Master.

How Session timecodes work

Embedding a

Session timecode of your own selecting in your video files, where

you set the exact hour, minute, second, and frame your recording timecode will begin, requires certain conditions:

• The starting timecode cannot be changed while a recording is underway.

• The source window will display the starting timecode (written to the XMP metadata) only for files that began at the start time of the session.

• The timecode of any file that starts recording later, will be written as the start timecode plus the offset (the input's staggered start time).

• The number in the frame field cannot be greater than the number of frames per second, minus 1 of the current frame rate. For frame rates of 50fps and 60fps, the frame field is limited to 49 and 59 respectively.

• If Drop-frame is selected, frame numbers 00 and 01 of the first second of every minute are not valid, except for when the number of minutes is divisible by ten.

¦NoteBoth the starting timecode and drop-frame (see “Drop-frame timecode")

settings are saved for the next time the VS4Recorder Pro is used. These settings can only be used when the VS4Recorder Pro is:

• In Multi-Cam mode or when using VS4Control

• The frame rates of all the selected inputs are the same

• The Session time code is selected

Setting the starting Session timecode

1 Select Session in the Timecode section of the VS4Recorder Pro settings.

2 Enter valid time values in the adjacent field.

3 Start the recording session.

The timecode, as set, increments from the starting value.

System Time

You can choose to embed the current time in the video files by selecting the

System Time option. The system time is taken from the local computer

configuring the VS4Recorder Pro settings.

Settings

This selection makes the time-of-day, as interpreted by the machine, the recording starting value, and the time-based timecode increments in the control window once the recording starts. When not recording, with this option selected, the previous session's timecode is displayed.

¦NoteWhen using VS4Control, this option will only be available on the Master.

Drop-frame timecode

VS4Recorder Pro gives you the option to use a drop-frame or non-drop-frame timecode in your recording session. Select the

Drop-frame option button to

embed your timecode in the drop-frame format.

For NTSC video, timecode is normally produced by a generator that counts at 30 frames per second. NTSC color signals, however, actually have a display frequency close to 29.97 frames per second. Drop-frame timecode compensates for this time difference by dropping two frames from the count every minute except for every tenth minute so that the timecode matches clock time.

Remarks

• A drop-frame timecode is formatted and will display as: HH:MM:SS;FF

• A non drop-frame timecode is formatted and will display as: HH:MM:SS:FF

VU meters

VS4Recorder Pro includes VU meters in each of the source windows (see

“Source window” on page 19) that allow you to visually monitor the audio levels

of up to eight audio channels per source. The VU meters can display two, four, six, or eight channels depending on the number of audio channels to record, and show the VU peak per channel. The VU meters can also be set to remain on screen, or auto-hide after a period of mouse inactivity. The following sections detail how to display and customize the VU meters.

Enabling VU meters

To display the VU meters, you must enable the window by selecting

ON. The number of audio channels that are visible in a

source’s VU meter depends on the number of audio channels that are being recorded for that source. If a source’s audio is disabled for recording, the source’s VU meter will not appear (see “Enabling audio and selecting audio channels” on

page 45).

Show VU peak

When

Peak is selected, the VU meters indicate the highest audio level (peak) that

is reached for each channel during a source recording. If at any point the audio level for a given channel goes above 0 dBFS, the peak LED illuminates and remains illuminated for the duration of the source recording.

VS4Control

You can enable or disable VS4Control from the option button at the bottom of the VS4Recorder Pro unlimited number of SDI streams at the same time (each computers with a VS4 card). One VS4, set as a master, can synchronize the capture on four computers (one master, three slaves) over a network. Recording using VS4Control is like recording in Multi-Cam mode, but with the ability to link with more machines and sources.

For a VS4Control recording session, you require:

• A network. All systems must be on the same subnet.

• A valid source connected to Input 1 of each networked machine.

• All cameras genlocked to the same source.

• All cameras output at the same resolution (same frame size and rate).

Settings dialog. VS4Control allows you to capture an

VS4Control

VS4Control status pane

The VS4Control status pane is where all pertinent information regarding your VS4Control recording session is located, such as your session’s Multicast IP address (see “Multicast IP address” on page 53), the machine names, and the machine statuses. The machine statuses are as follows:

• Ready The machine is ready to record and is waiting to receive a start to

record command from the Master, or a slave is ready to capture in the next recording session (joining a group that is currently recording).

• Recording The machine is currently recording/capturing.

• Not responding The machine joined a group, but is not responding

(perhaps due to a crash).

¦NoteAs soon as a machine joins the group, it notifies the network that it is

connected and accessible. If a notification is missing, the machine that is not responding will be tagged with a

Not responding status.

• If Input 1 of the Master is disconnected during a capture, the session will continue capturing, but only black frames will be captured on Input 1 of the Master.

• To stop the session on the slaves, you will have to disable VS4Control.

• If the Master becomes inoperative during the capture:

$ The slaves will continue to capture.

$ When restarting the VS4Recorder Pro on the Master, the Master will be

able to join the group, while the slaves continue capturing.

$ Pressing the Record button on the Master will start the capture on the

Master without affecting the recording on the slaves.

$ Stopping the capture on the Master will stop the session (Master and

slaves will stop).

• If a slave becomes inoperative during the capture, the session continues on the Master and functional slaves.

• During a capture:

$ A slave can exit the VS4Control via the Settings dialog. If the slave was

capturing, then the capture will be automatically stopped and the main Record button becomes available. The machine can rejoin the group as a slave, but the capture will not start automatically. For this machine to capture, the Master must stop, and then restart the capture.

$ A machine can only join the group as a slave, and a Master cannot leave

the group (unless having become inoperative).

¡ Important Once a machine in a group has been assigned Master on the

specified multicast IP address with VS4Control enabled, it will not be possible to set another machine to Master in that group.

¦NoteMaster and Slave settings are saved in the settings of the VS4Recorder

Pro and reloaded when the application is launched.

File splitting and Capture duration using VS4Control

You can split captured video files at set intervals or set a capture duration limit that stops a recording session after a specific time limit to protect and better manage the storage of your video files. For more information, see “Capture

duration” on page 37 and “Automatic file splitting” on page 38.

¦NoteThe Capture duration option will not be available for slave units.

Multicast IP address

The use of a Multicast IP address is what allows for several VS4 units to be centrally connected, as slaves, to one VS4, as a master.

VS4Control

Audio monitoring enabled Audio monitoring disabled

When first opening VS4Recoder Pro, a (valid) default multicast IP address is displayed in VS4Control, but it can be changed (an entered address will be validated). The change must be done on all the machines connected to the same Master.

Since the Multicast IP address is editable, anyone joining an address on a network is part of one group session; however, you can use several addresses within a network, where smaller groups can work independently, with their own master and slave machines, but still part of the same network.

¡ Important In order to change the Multicast IP address, you must first disable

VS4Control.

Audio monitoring

You can monitor any audio pair from one input source by enabling audio monitoring for the source in the corresponding source window. VS4Recorder Pro automatically directs the selected audio pair to your computer’s sound card for monitoring through the computer speakers.

¥Tip You can also use the VU meters to visually monitor up to eight audio

channels per source. For more information, see “VU meters” on page 50.

Enabling/disabling audio monitoring

To enable/disable audio monitoring for a source, click the Audio Monitoring button in the corresponding source window popover (see “Source window

popover” on page 20).

Selecting the audio pair to monitor

To select the audio pair to monitor, hover the mouse pointer over an Audio Monitoring button to open the channel selection flyout, and then click the desired audio pair.

Chapter 4, Using the VS4Recorder Pro Application

View modes

The VS4Recorder Pro interface offers different modes for viewing your input sources. You can choose to view all four input sources simultaneously in quad-view mode, or cycle through isolated inputs for viewing in single-view mode. VS4Recorder Pro also includes a full-screen option for both source-view modes. You can switch between the VS4Recorder Pro view modes at any time without affecting the recording, and all view modes offer the same on-screen display and record functionality.

¥Tip You can use the VS4Recorder Pro shortcut keys to switch between the

various view modes (see “Keyboard shortcuts” on page 58).

Source view

VS4Recorder Pro offers two modes for viewing your input sources: quad-view mode and single-view mode.

Quad-view mode

This mode displays all four source windows within the current VS4Recorder Pro interface.

To switch from single-view mode to quad-view mode, click the Source View button in any of the source window popovers (see “Source window popover” on

Working with editing applications

You can use the VS4Recorder Pro video and audio files in your favorite editing application for post-event editing. However, VS4Recorder Pro embedded metadata, such as timecode and label, is supported in Adobe Premiere Pro (and other Adobe applications, such as Adobe Bridge) CC and CS6. For more information, see “Viewing VS4Recorder Pro metadata in Adobe Premiere Pro" in this section.

Working with MPEG-2 I-frame .avi files on a Windows system requires that the Matrox Video for Windows (VFW) software codecs be installed. The VFW software codecs are automatically installed along with your Matrox VS4 software. If you plan on working with MPEG-2 I-frame .avi files on a Windows system without Matrox VS4, MXO2, CompressHD, Mojito MAX, or Mojito 4K hardware, you must download and install the Matrox VFW codecs on that system.

To work with MPEG-2 I-frame .avi files on a Mac OS system without Matrox MXO2, CompressHD, or Mojito MAX hardware, you must download and install the MPEG-2 I-frame codec on that system. To download the Matrox VFW software codecs (Windows) or MPEG-2 I-frame codec (Mac OS), visit the Support section of our website at www.matrox.com/video/support.

When using VS4Recorder Pro video and audio files for multi-camera editing, realtime performance is supported only for MPEG-2 I-frame .avi files in Adobe Premiere Pro CC and CS6 on a Windows system with Matrox VS4, MXO2, Mojito MAX, or Mojito 4K hardware installed. For more information, see

“Multi-camera editing" in this section.

¦NoteMPEG-2 I-frame .avi files are not supported in Avid editing applications

on Windows systems.

for multi-camera editing with Adobe Premiere Pro CC and CS6 (see “Event

markers” on page 29).

Chapter 4, Using the VS4Recorder Pro Application

Using Matrox VS4 with

Telestream Wirecast

This chapter describes how to stream and record your video input feeds using Matrox VS4 in Telestream Wirecast.

Overview

You can use Matrox VS4 as an input device to feed live video and audio to Telestream Wirecast for streaming, and simultaneously record all your original video feeds to disk. The easy-to-use Matrox ISO recording tool lets you create high-quality recordings of your feeds, ready for post-event editing in your favorite editing application. The combination of Matrox VS4 and Telestream Wirecast for Windows lets you switch or mix multiple live video feeds and pre-recorded clips while adding graphics and effects. This solution is ideal for Internet broadcasts of sports, religious services, corporate meetings, and other live events. Tight integration of Matrox VS4 using the Wirecast input source SDK ensures the highest level of reliability and stability for your streaming productions. Matrox VS4 automatically detects the presence, resolution, and frame rate of all your inputs. Because all inputs on Matrox VS4 are independent, you can use HD and SD cameras in the same production.

Using Wirecast, you can choose any stereo pair for your streaming production while simultaneously recording all eight channels to disk using the Matrox ISO recording tool. You have complete flexibility to go from a simple stereo mix to surround sound for your post-event editing needs.

You can use up to two Matrox VS4 cards in your system. In a two-card system, all eight VS4 inputs can be used as input devices to feed live video and audio to Telestream Wirecast for streaming. ISO recording is supported on the four inputs of the primary VS4 (see “Selecting your primary VS4 card” on page 93).

Using Matrox VS4 for streaming

Matrox supports a maximum of two VS4 cards per system. With four SDI inputs on each VS4 card, your VS4 system offers up to eight inputs for your live video feeds. This section provides instructions on how to use VS4 as the input device for video and audio in Telestream Wirecast for streaming. For details on how to add shots in Telestream Wirecast, see your Wirecast documentation.

1 Connect your video source(s) to the VS4 SDI input(s) (see “Connecting

devices to Matrox VS4” on page 11).

¡ Important If connecting sources with different video formats, the sources

must have compatible frame rates. For a list of compatible frame rates, see

“Supported input formats” on page 10.

2 In Telestream Wirecast, add a new shot for every VS4 input source that you

want to stream.

3 For each VS4 shot added in step 2, the corresponding input’s audio is

automatically selected as the audio source. If desired, you can change a shot’s audio source to another VS4 input or to a system audio source as explained in your Wirecast documentation.

Chapter 5, Using Matrox VS4 with Telestream Wirecast

¦NoteFor a VS4 input or system audio source to appear in the list of audio

sources, a shot must have been added for that VS4 input or system audio source.

Audio settings

Click

Audio Settings for each VS4 input to specify the settings that you want

for your recorded audio:

•

Audio Channels Specifies the number of channels to record from your

VS4 input:

$ When 0 is selected for this option, audio is not recorded. Therefore, audio

will not be embedded in the video file, and separate audio files will not be created.

$ When 2, 4, 6, or 8 is selected, the Matrox ISO recording tool embeds the

first audio pair (channels 1-2) from your input source in the video file. Unless you choose to record embedded audio only, separate .wav or .aac audio files will be created for the first two, four, six, or eight audio channels from your audio source respectively.

•

Saving and loading record presets

In the

Matrox ISO Record dialog box, once you’ve specified the Matrox ISO

record settings that you want for a VS4 input, you can save your settings as a preset and load the preset at any time to apply those settings to an input with a compatible video format.

• Save To save the current settings of a VS4 input as a custom preset, click

beside the input and choose

Save Preset. You’ll then be prompted to

enter a name for your preset. Because the video file type is saved in the preset, you should include the video file type, such as AVI, in your preset name so that you can easily identify your custom presets.

• Load When you load a preset, the video file type, codec settings, audio file

type, and audio settings are applied according to the preset. To load a preset for a VS4 input, click beside the input, choose select the preset that you want in the displayed dialog box. Only presets that are compatible with your input’s video format will be listed.

¦NoteTo delete a preset, from the Load Preset dialog box, select the preset,

and then click .

Copy.

Load Preset, and then

• Paste To paste the copied settings to another VS4 input, click beside the input and choose

Paste. The video file type, codec settings, audio file

type, and audio settings that are compatible with your VS4 input are applied. Default settings will be applied for any incompatible settings.

Matrox VS4 file naming conventions

The base name specified under Record Path in the Matrox ISO Recording tool applies to both the video and audio files that are recorded, but the naming conventions for video and audio files differ as follows:

• Video files Recorded video files contain the base name, VS4 input, and recording number using the following convention:

basename_input_recordingnumber

For example, if the base name for Input 1 is Record, the resulting file will be named Record_1_0. You can also have more than one recording for a given input. In this case, the files are differentiated by a recording number. This occurs when:

$ You clear and then re-select a previously selected input during a recording

session. In this case, you will have a different file for each selection sequence. For example, if you’re recording Input 1 with the base name Record, and you select Input 1 three times during a recording session, the resulting video files will be Record_1_0, Record_1_1, and Record_1_2.

$ You disconnect a source from a selected input during a recording session,

and then connect a source with a different video format to the same input. For example, if you’re recording an NTSC source connected to Input 1 to an .avi file with the base name Record, and then you connect a 720p at

59.94 fps source to the same input, the resulting video files will be Record_1_0, and Record_1_1. If you connect a source with the same video format as the original source, the recording will continue in the original video file (that is, a separate video file will not be created).

• Audio files If you’re recording to separate audio files, the audio files are named the same as the video files, except that they also include the audio channel type (mono or stereo) and an incremental suffix using the following convention:

basename_input_recordingnumber_channeltypesuffix

For example, if you’re recording Input 1 with the base name Record,

Channels

is set to 8, and Stereo is selected as the Audio Channel Type,

the resulting audio files will be named Record_1_0_Stereo1, Record_1_0_Stereo2, Record_1_0_Stereo3, and Record_1_0_Stereo4. If

Mono is selected as the Audio Channel Type instead of Stereo, eight files

will be created instead of four, and the files will be named Record_1_0_Mono1, Record_1_0_Mono2, Record_1_0_Mono3, and so on.

Recording your source video to disk

Record functionality

This section describes the VS4 functionality regarding the recording session, record timecode, and input recording.

Recording session

A recording session begins when you click , and ends when you click . During a recording session, all selected inputs are recorded. See “Input

recording” on page 74 for the input recording methods.

¡ Important If the status light turns red when recording, this indicates that one

or more of the selected inputs experienced dropped or skipped frames. After the recording session ends, check the Record.Log file to see the dropped/skipped events for each recorded input (see “Record log file” on page 77).

Record timecode

Starting a recording session also starts the record timecode for each selected input. Depending on the video input frame rate, Matrox VS4 displays the timecode in either drop frame (HH:MM:SS;FF) or non-drop frame (HH:MM:SS:FF) SMPTE format. Drop frame format is used for NTSC, 23.98 fps, 29.97 fps, and 59.94 fps video, and non-drop frame format is used for all other video frame rates, such as PAL and 25 fps. If you select an input at any time during a recording session, the record timecode for that input starts when you select the input. A recording’s timecode stops only when the recording ends for that input file. See “Input recording” on page 74 for information on stopping an input recording.

Input recording

This section describes the various ways of recording an input source, and stopping an input recording:

¦NoteIf an input with no input signal (disconnected) or an invalid input signal

is selected during a recording session, the recorded video will be black with no audio. Check the Record.Log file to see where black frames are recorded (see

“Record log file” on page 77).

Recording methods:

• Selecting an input before starting a recording session If an input is

selected before starting a recording session, Matrox VS4 creates a recording for that input when the recording session starts. This includes an “invalid input,” which refers to an input with no input signal (disconnected) or an invalid input signal. In this case, the video for an “invalid input” will be black and the video format of the recorded file will be the last valid video format detected for that input. When connecting a valid source to an “invalid input” during a recording session, make sure your source’s video format matches the format of the “invalid input” to avoid creating a new file. See

Chapter 5, Using Matrox VS4 with Telestream Wirecast

“Input states and video formats” on page 76 for information on how to

determine the video format of an “invalid input.”

• Selecting an input during a recording session You can select an input at any time during a recording session to begin recording that input. If you clear and then re-select an input during the same recording session, a separate file will be created for each selection sequence. The files are differentiated by a recording number (see “Matrox VS4 file naming

conventions” on page 73).

• Connecting an input source during a recording session You can connect an input source to an unselected input during a recording session, and then select the input to record your source feed. If you disconnect the source from a selected input during a recording session, and then connect a source with a different video format to the same input, a new file will be created for that input. The files are differentiated by a recording number (see “Matrox VS4

file naming conventions” on page 73). If you connect a source with the same

video format as the original source, a separate video file will not be created and the recording will continue in the original video file.

To stop an input recording:

• Clear an input during a recording session Clearing a selected input during a recording session stops the recording for that input. This is done without affecting the recording of other selected inputs.

• Connect a different video format to a recording input If you disconnect a selected input’s source, and then connect a source with a different video format than the original source, the original recording ends, and a new file is created for the new source. For example, if you’re recording an NTSC source connected to Input 1, disconnect the NTSC source and then connect a 720p at 59.94 fps source to the same input, the NTSC recording ends and a new 720p at 59.94 fps recording begins.

• Stop the recording session Click to stop the recording session. In this case, all input recordings will stop.

WAV audio recording

When you record audio to separate .wav files along with your video, the .wav files can have a maximum file size of 4 GB. This means that depending on your specified audio settings, the .wav audio file has a maximum duration. This restriction does not apply to the embedded audio in the video file, which can last as long as the associated video. The following table lists the approximate maximum duration for a separate .wav audio file based on the audio settings:

Record status

Matrox VS4 includes a record status indicator. If the indicator remains green throughout the entire recording session, all input recordings completed without any dropped or skipped frames. If dropped or skipped frames occur for any input recording, the indicator turns red for the duration of the recording session. Check the Record.Log file to see the dropped/skipped events for each recorded input (see “Record log file” on page 77).

Input states and video formats

Matrox VS4 automatically detects the video format of the source connected to a VS4 input and displays it in the Matrox ISO Recording tool.

Chapter 5, Using Matrox VS4 with Telestream Wirecast

Matrox VS4 displays the following input states:

• Valid input signal If a valid signal is connected to an input, such as 1080i at 29.97 fps, the video format is displayed under the input label. If the input is selected for recording, the resulting video file will be in the displayed video format.

• No input signal/Invalid input signal If VS4 detects no input signal or an invalid input signal for an input, will be displayed respectively. If the input is selected, the input indicator switches between displaying the state (

Signal

) and the last valid video format detected for that input. If you record an input in this state, the resulting video file (black video) will be in the displayed video format. For example, if the input indicator shows

Disconnected and NTSC, the recorded video file will be NTSC. If you

connect a valid source to an input in this state when recording the input, make sure the source’s video format matches the displayed video format to avoid creating a new file.

Disconnected or Invalid Input Signal

Disconnected or Invalid Input

Record log file

After every recording session (see “Recording session” on page 74) a record log file (Record.Log) is generated. The Record.Log file is located in the same folder that contains the files for that recording session. When dropped, skipped, or black frames occur during a recording session, the Record.Log file provides a breakdown of events by input, and the timecode of when the events occurred.

Working with editing applications

You can use the recorded video and audio files in your favorite editing application for post-event editing. However, working with Matrox MPEG-2 I-frame .avi files on a Windows system requires that the Matrox Video for Windows (VFW) software codecs be installed. The VFW software codecs are automatically installed along with your Matrox VS4 software. If you plan on working with Matrox MPEG-2 I-frame .avi files on a Windows system without Matrox VS4, MXO2, CompressHD, Mojito MAX, or Mojito 4K hardware, you must download and install the Matrox VFW codecs on that system.

To work with Matrox MPEG-2 I-frame .avi files on a Mac OS system without Matrox MXO2, CompressHD, or Mojito MAX hardware, you must download and install the Matrox MPEG-2 I-frame codec on that system.
