About the Guide

This guide contains installation, configuration, and operating information for the VNR100.

In this guide:

• The term “recorder” refers specifically to the VNR100.

• The term “codec” refers to a VN-Matrix device that acts as an encoder and decoder.

• The term “stream” refers to multimedia that is constantly received by (and normally

presented to) an end-user while being delivered by a VN-Matrix encoding device.

• The term “element” refers to the video or graphics, audio, data, and whiteboard

(user data) content that is contained within a stream.

About the VNR 100 Recorder

The VNR 100 recorder is a network appliance capable of recording PURE3 video, audio, and data streams from VN-Matrix codecs and encoders. Multiple VNR 100 units can be configured together into systems to record and play back multiple, synchronized PURE3 streams.

The recorder is able to play and control a previously recorded file while simultaneously recording a new file, with a sustained aggregate bit rate of 150 Mbps. The VNR 100 is also able to replay, with time slip, a file that is still being recorded.

One or more VNR 100 recorders can be used in a VN-Matrix system. The system must be under the control of an Extron VNM Enterprise Controller, whether the system contains a single VNR 100 recorder or multiple recorders. Controlling multiple recorder devices or channels from a single master unit allows:

• Support for common transport controls for record and playback of grouped channels.

• Support for directory and file management of grouped recordings and playback.

Multi-channel systems are facilitated by maintaining full stream synchronization of multiple recorder devices across all stream elements (video, audio, data, and whiteboard) at all playback speeds in forward and reverse directions.

The recorder uses a network storage architecture, which makes the system highly scalable and flexible.

<Product Name> • <Section Title> 1VNR 100 • Introduction 1

The VNR 100 recorder is fully compatible with existing VNM Matrix products, including the:

• Extron 5-channel VN-Matrix recorder

• Extron VN-Matrix 2xx and 3xx codecs

• Extron VN-Matrix software decoder

• Extron VN-Matrix Enterprise Controller

• Extron VNS 104 Multi-Stream decoding software

VNR 100 Drives

The VNR 100 has two replaceable drives:

• Operating system (OS) drive — contains the VNR 100 operating system.

• Media drive — contains the video, audio, data, and whiteboard information files that

have been recorded by the VNR 100.

Both these drives can be replaced easily. Replacing the media drive does not require any device specific data to be updated on the OS drive. For complete instructions on replacing the drives, see OS Drive Replacement Kit (page 15) and Media Drive Replacement Kit (page 18).

VNR 100 • Introduction 2

Overview of Recorded Streams

Encoders convert video signals to highly compressed signals that can be transferred over a network.

• The VNR 100 records the compressed signals from the network, without further

processing.

• As a minimum, each recording contains a video element.

• A recording may also include elements containing audio, data, and whiteboard

information (if these are present and enabled at the encoder). If these are selected for storage, each element is stored as an individual file within the same directory.

Overview of Stream Playback

• The VNR 100 plays back saved data without processing. It is already in a highly

compressed format that can be transferred over a network.

• When a recording that contains multiple elements is selected for playback, all the

necessary files are loaded.

• The video content is always played back.

• When present, audio, data, and whiteboard elements may be enabled or disabled for

playback. If they are enabled, the audio, whiteboard, and data elements are always slaved to the video stream.

Decoders take the highly compressed signals from the network and reconvert them to the uncompressed format required by a display device.

Transport Protocols Used for Streaming

Source data from a VN-Matrix encoder can be distributed to multiple displays or decoders (one-to-many) or to a single display or decoder (point-to-point). A previously recorded stream can be distributed in the same way and, as the source of an encoded stream, the recorder may be thought of as an encoder in this context.

A stream may be transported over the network from the source (encoder, recorded stream) to the display (decoder) using one of three methods:

• Multicast Real-time Transport Protocol (RTP)

• Unicast Real-time Transport Protocol (RTP)

• Unicast Transmission Control Protocol (TCP)

By default, the VNR 100 recorder provides a choice of unicast RTP or unicast TCP transport protocols. A multicast transport protocol may be configured if required (see the Enterprise Controller User Guide).

NOTES:

• During playback of a recorded stream, the transport protocol can be TCP, RTP, or

RTP Multicast. The protocol is speciﬁed on the VNM Enterprise Controller.

• When a stream is recording, the VNR 100 may be considered as a display

(decoder) device.

VNR 100 • Introduction 3

Multicast RTP — An Overview

Encoder sends data using to a multicast gr

oup.

Multicast RTP allows a source to be displayed on multiple displays. This method uses RTP, which is a real-time variation of UDP (User Datagram Protocol).

Figure 2. Multicast RTP Streaming

The source encoder uses RTP to send data to a multicast group. The source does not need to know the IP address of the decoders that are using the source.

RTP provides very low latency which is important for video streaming. Unlike other protocols, RTP packets include a time stamp. If packets are received in the wrong order, they are sorted into the correct order for display or discarded if the time stamp is out-of-date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed. When data packets are lost (for example, due to excessive network traffic), the decoder devices carefully manage the data stream to minimize any image disruption.

VNR 100 • Introduction 4

Unicast RTP — An Overview

Similar to multicast RTP, this method uses a real-time variation of UDP protocol, called unicast RTP. This method can be used where the network infrastructure does not support multicast traffic. Typically, this protocol is used for point-to-point configuration (single source to single display), but can be configured to use up to a maximum of four displays.

NOTE: The encoder sends an individual stream to each decoder. This means that the

total bandwidth of the VN-Matrix system increases as more decoders are added.

Unicast TCP — An Overview

This method transports data using standard TCP and should only be used for single point-to-point transfer of data.

TCP is a connection-based protocol and, therefore, data is guaranteed to be delivered. However, in the event of excessive network traffic, delivery may be delayed which will impact real-time performance.

VNR 100 • Introduction 5

Definitions

PURE3 — PURE3 is specifically designed for network transmission of real time media (such as video or graphics, audio, data, and whiteboard elements). It features both spatial and temporal image compression, which allows for efficient bandwidth usage and eliminates the need for forward error correction.

• PURE3 streams always contain video or graphic elements.

• PURE3 streams may contain audio, data, and whiteboard elements that are associated

with the video and graphic elements.

Streaming media (stream) — This term refers to multimedia that is constantly received by (and normally presented to) an end-user while being delivered by a streaming provider. Internet television is a commonly streamed medium. Streaming media (stream) in this guide refers to a PURE3 media stream that is produced by a VN-Matrix encoding device.

Element — This term refers to the video, graphics, audio, (user) data, and whiteboard (annotation data) content that is contained within a stream.

Device license — This term refers to the number of licensed features that are available on a device within a VN-Matrix system. All devices contain a default license that offers a default level of functionality (see the VNM Enterprise Controller User Guide, which is available at

www.extron.com).

Controller license — This term refers to the license that is supplied to the VNM Enterprise

Controller (see the VNM Enterprise Controller User Guide).

(User) Data — This refers to the transfer of user data between an encoder and a decoder. User data is created at the encoder, placed into the PURE3 stream, and sent to the decoder. The data is received in the same form that it was transmitted. This method of data transfer is unidirectional and can only be sent from an encoder to a decoder.

Whiteboard (wb) data — Also known as annotation data, whiteboard data outputs text and simple pointer annotation onto local displays that are connected to VN-Matrix encoders or decoders. This type of data is bidirectional, which allows a decoder to send whiteboard data to an encoder.

VNR 100 • Introduction 6

Features

Simultaneously record and play back VN-Matrix AV streams — uses customer assets more effectively by allowing free use of imaging sources independent of playback and review.

Time-shift playback capabilities support time slip or chase play — offers flexible timing for playback of recorded events to accommodate local schedules.

Transport controls include: play, pause, and variable speed playback at 2x, 4x, and 8x speeds in forward or reverse as well as single frame advance in forward or reverse — allows time-efficient review and scanning over recorded content.

System scalability — create multi-channel recording systems using multiple VNR100

units, providing flexibility that can be applied in a wide range of applications; develop recording systems with few or many audio and video channels.

System synchronization — synchronize playback across multiple VNR 100 units — supports lip sync, genlocked decoding, scaled playback across multiple VNR100 units, synchronization of recorded external ancillary data to audio and video streams, and the ability to support recording and playback of videowalls, or multi-display systems.

PURE3 codec — provides visually lossless compression, efficient bit rates, and absolute frame encoding supporting high quality content, lip sync, synchronization of multi-screen playback, and playback transport controls for efficient and accurate visual documentation.

Removable storage — provides flexibility to secure recorded data in sensitive or secret applications.

Replacement media drive and operating system drive available — use in data-sensitive applications where independent storage is required to record different events.

Compatible with VN-Matrix 200, 225, and 300 series and VN-Matrix Software Decoders — maintains value of existing and investments in Extron VN-Matrix products.

gcode Frame Translator Utility — allows the conversion of existing VN-Matrix video

recordings into individual still frames (see gcode Frame Translator Utility Instructions on page28).

Initial Configuration of the VNR 100

The initial configuration of the VNR 100 allows it to connect to the Enterprise Controller. Once it is integrated into the Enterprise Controller network, the VNR 100 will be completely controlled by the Enterprise Controller.

By default, the VNR 100 is pre-configured with the following network settings:

• IP Address: 192.168.254.254

• Subnet Mask: 255.255.225.0

• Port Number: 8080

You will need to contact your network administrator to find out the IP address for the Enterprise Controller.

To perform the initial configuration, follow these instructions:

1. Initial configuration is through the browser of a computer connected to the

same network as the VNR 100. In the browser address bar, enter the IP address of the recorder followed by a colon and the port number (for example:

192.168.254.254:8080).

The login page opens:

VN-Matrix System Port Usage

The VN-Matrix system uses a variety of network port numbers for streaming and intercommunication functions. Just as the universal “telnet” function typically uses TCP port number 23, VN-Matrix uses specific port numbers for its operation.

The table on the following page lists the port numbers used by the VN-Matrix series products. The port numbers are, in most cases, for the sender. Port numbers used for receiving are less important in regards to security.

When configuring a network, make sure it allows traffic on the ports required for your given application. The ports highlighted in yellow accommodate most simple applications.

VNR 100 • Reference Information 21

Mounting the VNR 100

This section provides information on installing the VNR 100 into a rack cabinet. Rack installation requires the use of the provided rack mount kit.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:

1. Elevated operating ambient temperature — If the unit is installed in a closed or

multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (TMA: +122 °F, +50°C) specified by Extron.

2. Reduced air flow — Install the equipment in the rack so that the equipment gets

adequate air flow for safe operation.

3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical

loading does not create a hazardous condition.

4. Circuit overloading — Connect the equipment to the supply circuit and consider the

effect that circuit overloading might have on overcurrent protection and supply wiring. Consider the equipment nameplate ratings when addressing this concern.

5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted

equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting Using Rack Rails

The rack mounting kit is used to mount the VNR 100 in a Telco rack or a standard 19inch(48.3 cm) wide rack with four vertical posts, one in each corner.

ATTENTION:

• When multiple units are mounted in the rack, load the rack from the bottom to the

top, with the heaviest unit at the bottom. If this is the only unit mounted in the rack, it should be mounted at the bottom.

• Lorsque plusieurs unités sont montées dans le rack, chargez le rack du bas vers le

haut, en commençant par l’unité la plus lourde. Si c’est la seule unité montée dans le rack, elle devrait être montée en bas.

• With the rack rails collapsed, this unit requires a minimum rack depth of 25.5inches

(64.8 cm).

• Lorsque les rails de rack sont pliées, cette unité nécessite une profondeur de rack

minimum de 64,8cm (25,5inches).

• The total room required with the rack rails fully expanded, is 33.5inches (85.1 cm).

• L’espace total requis avec les rails de rack entièrement étendues est 85,1cm

(33,5inches).

gcode Frame Translator Utility Instructions

Introduction

The VN-Recorder Frame Translator utility described in this section allows the conversion of existing VN-Matrix video recordings to individual still frames. These frames can be assembled into standard video, HD video, or other types of media files using third-party editing applications.

The utility also allows audio files to be converted to .WAV format.

NOTE: The information in this document is accurate for VNR100 devices running

firmware version 9.2.1 or later.

This section provides information on:

• Overview

• Preparation for Using the gcode Frame Translator Utility

• Description of the Frame Translator Utility

• Recording File Directory Nomenclature

• Frame Translation Procedure

• Example Strings

• Advanced Use

• Working with Video and Audio Streams

Overview

To create a media file from a VN-Matrix recording:

1. Use VN-Matrix encoders and recorders to create a VN-Matrix recording.

2. Create a directory on the VN-Matrix recorder, where the still frames and audio file will be

stored (see Recording File Directory Nomenclature on page 32).

3. Use the Frame Translator Utility to export the video recordings as still frames to the

directory created in step 2. If required, use the utility to export audio recordings as WAV files to the same directory (see Frame Translation Procedure on page 33).

4. Transfer the still frames and audio files to a PC running a third-party editing application.

5. Create a video or media file from the still frames and audio file.

The main focus of this section is step 3, the Frame Translation Procedure on page 33.

VNR 100 • Reference Information 28

Use the command line window to enter the gcode commands that are described in the following section.

VNR 100 • Reference Information 30

Description of the Frame Translator Utility

The Frame Translator utility is a command line utility that is run from a terminal window on the VN-Matrix Recorder. The command line follows this structure:

./gcode command flags

The available command flags are:

Flag Description

-g

Enables graphical output. Opens a window that displays each frame in succession after it has been exported.

NOTE: A local display must be connected to the VN Recorder.

-t

Enables targa ﬁle output (.tga), one ﬁle per frame. Each frame is labelled video and numbered sequentially from 1 onwards (for example video000001.tga).

-j quality

Enables jpeg ﬁle output (.jpg), one ﬁle per frame. The quality parameter is a value between 0 and 100 that sets the compression of the jpg ﬁle from the minimum quality value (0, or maximum compression) to the maximum quality value (100, or minimum compression). A value of 100 produces the best quality image with the largest ﬁle size. A typical quality value is 80.

-o outputdir

outputdir

deﬁnes the path to the directory where the output ﬁles are stored. If this ﬂag is not

speciﬁed, the ﬁles are output to the same directory as the gcode utility (typically /home/matrix_

rec/VNRecorder_verx.y.z

NOTE: The -o flag does not create the directory. To create a directory, see step 1 of Frame

Translation Procedure on page 33.

Each frame is labelled video and numbered sequentially from 1 onwards (for example

video000001.tga). To aid identiﬁcation and help with ﬁle management, Extron recommends

that a new output directory is created for each gcode ﬁle conversion.

-i inputdir

inputdir

deﬁnes the path to the source directory containing the recording (*.rec) that is being

exported. For information about selecting the correct directory name, see Recording File

Directory Nomenclature on the following page.

-l

-s start time

-f end time

Lists the start and end times for the speciﬁed recording. This ﬂag is used in conjunction with the

-i ﬂag, which speciﬁes the directory where the recorded ﬁles are stored.

Speciﬁes the time stamp from which the gcode process starts. The time is in the format

HH:MM:SS.tt.

Speciﬁes the time stamp at which the gcode process ends. The time is in the format

HH:MM:SS.tt.

NOTE: Setting a start time is optional. It is recommended that an end time is always

specified. Failure to do this may cause the command window to freeze after the last frame to process. If this happens, use the <Ctrl>+<C> keys to end the process.

-h

Print help screen. This displays a list of ﬂags and a brief description in the terminal window.

NOTES:

• When using the -j, -i, -o, -s, and -f ﬂags, it is necessary to leave a space between the command ﬂag and

the parameter that follows (for example: -o /home/matrix_rec/Recording_Files/recording1).

• Only one stream can be exported at a time. Video and audio must be exported separately (see Working

with Video and Audio Streams on page 37).

Recording File Directory Nomenclature

The -i flag must be followed by the directory path that contains the recording that is being exported.

A typical path may look like:

/home/matrix_rec/Recording_Files/Mission1/OTW_5400036.0.0_r0_s0.rec

where:

/home/matrix_rec/Recording_Files/ is the factory default path, where recording files

are stored.

Mission1/ is a user-created subdirectory for housing a recording session. This session may

contain recordings from multiple VN-Matrix recorders.

OTW_5400036.0.0_r0_s0.rec is the directory that holds the recording files for a single

encoded stream, recorded from one VN-Matrix encoder. The name reflects whether the folder holds a recorded video, audio, data, or whiteboard stream. The individual naming elements have the following significance:

Naming element Explanation

OTW

_5400036

_r0

_s0

Refers to the name assigned to the VN-Matrix encoder at the time of the recording.

Refers to the serial number of the VN-Matrix encoder.

This digit refers to the type of recorded content. The options are:

• 0 — video

• A0 — audio

• D0 — data

• W0 — whiteboard.

Indicates the stream type:

• 0 — RTP stream

• 1 — TCP stream

Indicates the recording channel:

Video Streams

r0 — video recording channel 1

•

Audio Streams

• r1 — audio recording channel 1

Indicates the recording number. This value increases incrementally if a subsequent recording with the same name is made.

Frame Translation Procedure

Use the Frame Translation procedure as follows:

1. Create an output directory.

To create a new directory on the VN-Matrix Recorder:

a. Return to the WinSCP window.

b. Use the mouse to select the window showing the VN Matrix Recorder folders.

c. Navigate to the required location. Use the <F7> key to launch the Create folder

dialog.

d. Enter the name of the folder and click OK in the dialog box.

2. Navigate to the directory holding the Frame Translator utility.

The gcode frame translator utility may be found in the same directory as the VN-Matrix recorder application at the following location:

/home/matrix_rec/VNRecorder_verx.y.z

where verx.y.z denotes the version number of the VN-Matrix application files. This name may vary slightly depending on which version is installed.

In the Command line window, navigate to the directory containing the Frame Translator utility, using the following commands:

cd — change directory

cd .. — go one directory back up the file hierarchy

ls – list the directories and file at the current location

pwd — show the working directory (your current location).

Using username "matrix_rec". matrix_rec@10.100.245.87's password: Last login: Wed Feb 12 09:26:11 2014 from 10.100.247.143 [matrix_rec@localhost ~]$ ls

Recording_Files VNRecorder_ver9.2.2

[matrix_rec@localhost ~]$ cd VNRecorder_ver9.2.2/ [matrix_rec@localhost VNRecorder_ver9.2.2]$

Figure 29. Navigating to the Frame Translator Utility Directory

3. Configure the gcode command line in the terminal window.

Once you are in the correct directory, the command ./gcode runs the application although, on its own, it won’t do anything until it is told which file to work with. Decide which command line flags are needed and type the command line in the terminal window. For example:

./gcode -t -o /home/matrix_rec/Recording_Files/Video_Audio_ Data/TGA -i /home/matrix_rec/Recording_Files/Video_Audio_Data/ Chan1_1021526.0.0_r0_s0.rec -s 09:44:18.00 -f 09:44:20.00

NOTE: To run the utility, gcode must be preceded by the ./ characters.

VNR 100 • Reference Information 33

4. Press <Enter> to run the command. If an error is detected in the command line, an

indicator message appears in the terminal window.

If the command line is valid, the utility exports one image file per video frame to the designated output directory. The command line window will continually update as the process runs.

If you activate the graphic output flag (-g) for video exports, each frame appears on the screen as it is generated.

When the process is complete the command line prompt will be displayed:

NOTES:

• The average conversion time for a video ﬁle is approximately eight times the

length of the original recording. One second of recorder content may produce 60 exported image ﬁles.

• The conversion time for a audio recording is much shorter. An audio ﬁle that

is 2 minutes and 30 seconds in length is encoded to a .WAV ﬁle in less than 10seconds.

Example Strings

NOTE: The following examples are all unbroken character strings without a line break.

When the text moves to the next line, it is “text wrap.”

Example1 — decoding a file on the local graphics output

The command is:

./gcode -g -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• Each frame is displayed as it is generated (-g)

• No output directory is specified. By default the newly generated files are displayed on

the local display of the VN Recorder.

• The input directory is /home/matrix_rec/Storage/SAC_Test/Dave_Gilmour_

Dimming_of_the_Day_620027.0.0_r0_s0.rec

VNR 100 • Reference Information 34

Example 2 — decoding a file to Targa files and placing them in a specified output directory

The command is:

./gcode -t -o /home/matrix_rec/Targa -i /home/matrix_rec/Storage/SAC_ Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• Since there is no -g flag, the frames are not displayed as they are generated.

• The output is targa (tga) files (-t).

• The ouput directory path is /home/matrix_rec/Targa.

Example 3 — outputting JPG files with graphical output

The command is:

./gcode -g -j 80 -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• Each frame is displayed as it is generated (-g).

• The output is jpg files (-j).

• Since no -o flag is set, the output files are stored at the default location (/home/

matrix_rec/VNRecorder_verx.y.z

• The quality setting is 80%.

Example 4 — generating audio files, specifying the output directory.

To convert an Audio file to a .wav file and place in a folder “Targa.” The default name for the audio file is music.wav.

./gcode -o /home/matrix_rec/Targa -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.A0.0_r1_s0.rec

• The gcode utility recognizes that the file is an audio file (.AO) and automatically creates a

.WAV file with the name music.wav.

Advanced Use

Example 1 — stopping the export process

To stop the export process, press <Ctrl> + <C> at any time. Any image files that were generated prior to the process being stopped remain in the specified output folder.

Example 2 — determining the start and end points of the recording

The command is:

./gcode -l -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• The -l flag causes the utility to return the start and end time stamp of the recording:

17:45:27.53 - 17:47:27.65.

• The length of the recording is calculated by subtracting the start time from the finish

time (in this case 2minutes0.12seconds).

VNR 100 • Reference Information 35

Example 3 — start decoding a file at a time other than the beginning of the recording

The command is:

./gcode -g -s 17:45:37.53 -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• The file conversion starts ten seconds into the recording at 17:45:37.53.

Example 4 — finish decoding a file at a time other than the end of the recording

The command is:

./gcode -g -f 17:46:27.53 -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• The file conversion finishes at 17:46:27.53.

Example 5 — generating Targa files, specifying the output directory, and the start and finish times.

The command is:

./gcode -t -o /home/matrix_rec/Targa -s 17:45:37.53

-f 17:46:27.53 -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

• The output files are Targa (tga) files (-t)

• The output folder is /home/matrix_rec/Targa

• The file conversion starts at 17:45:37.53.

• The finish time is 17:46:27.53.

Working with Video and Audio Streams

When recording video content along with associated audio, the Start and Finish times for the each of the different recorded file types can differ by a small amount. Usually, the video file will be slightly longer and its start and end times will overlap the other files in the recording.

The times specified in the gcode utility must take this difference into account or synchronization of the content in the converted files will be lost, most noticeable in loss of lip sync between video and audio content.

When using the gcode utility to convert two files, the start and end times set for each file conversion must be the same and must overlap.

When setting the start time for a conversion, check the start times for each of the files that are to be converted and use the start time of the file that is last to start up, that is the latest start time.

For the end time, use a similar process but use the end time of the file that is first to stop, that is the earliest end time.

Example 1:

VideoStartTime=17:43:13.84 Video Finish Time = 17:49:11.36

Video ﬁle

Audio Start Time = 17:45:35.41 Audio Finish Time = 17:49:11.20

Audio ﬁle

In the above diagram, the start and end times of the video and audio files are different.

NOTE: The difference in start time is exaggerated to illustrate this point. In practice, the

difference will be much smaller.

To create the correct number of video frames and a .WVA file of the correct length you must specify the correct Start and Finish times within the gcode command line.

For this example a Start time of 17:45:35.50 (after both the audio and video files have started) and a Finish time of 17:49:11.00 (before either file finishes) would be appropriate.

This results in video and audio files of the same length being created. These files can be used with third-party video editing software to produce a correctly lip-synced file.

You will need two separate commands, the first to generate the video file and the second to generate the audio file:

./gcode -t -o /home/matrix_rec/Targa -s 17:45:35.50

-f 17:49:11.00 -i /home/matrix_rec/Storage/SAC_Test/ Dave_Gilmour_Dimming_of_the_Day_620027.0.0_r0_s0.rec

./gcode -o /home/matrix_rec/Targa -s 17:45:35.50 -f 17:49:11.00 -i / home/matrix_rec/Storage/SAC_Test/Dave_Gilmour_Dimming_of_the_Day_620027. A0.0_r0_s0.rec

• The first command uses a video file to produce targa files (-t).

• The second command uses an audio file (.A0) to produce a WAV file.

• Both the audio and video files are generated from the same start time (17:45:35.50) to

the same finish time (17:49:11.00).
