Chapter 1 Introduction

The Datavideo SE-1200 MU is a small, cost-effective, HD digital video switcher with easy-to-use
professional features. The SE-1200 MU can be controlled over a network and can even display a multi view
over the same network connection. This allows the SE-1200 MU operator to have the option of working in
a different room, or a different building, or even a different city!

The SE-1200 MU switcher offers four HD SDI and two HDMI inputs. Supported video formats include
1080i/50, 1080i/59.94, 1080i/60, 720p/50, 720p/59.94 and 720p/60. Output options include; two user
assignable HD SDI and two HDMI outputs. These user defined output options can be set up to provide
Clean Preview, Clean Program, Program with DSK overlay, Preview Out or Multi-view as well as Inputs 1~6.
The SDI or HDMI outputs can be taken to other Datavideo products (separate purchase) such as the HDR­70 HD recorder, TLM-170G HD monitor and can also be streamed to web based viewers using the
Datavideo NVS-25 Video Streaming Server.

The SE-1200 MU also features two analogue balanced XLR audio inputs for connecting an external audio
mixer such as the Datavideo AM-100 or AD-200. Tally and RJ-45 connections allow the switcher to be

Chapter 3 Network Setup

3.1 Initial SE-1200 MU Setup with a Windows Computer

The SE-1200 MU switcher is not supplied with a traditional hardware based control panel. Instead it is
controlled using a software user interface installed on your Windows-based computer. When new from
the factory the unit will initially have a static IP address of 192.168.100.101. The unit can be directly
connected to a Windows-based computer using an RJ-45 ethernet cable. The following set up should allow
you to initially configure the unit before moving it to an existing DHCP / LAN network.

• An RJ-45 ethernet cable.

• Windows 7/8/10 laptop or PC.

• The Datavideo SE-1200 MU controller

software.

Instructions

1. First connect the SE-1200 MU and the Windows computer together using an RJ-45 ethernet cable.

2. Turn on the Windows computer and set it to static IP set up within the Windows Network and

Sharing Centre.
In our example the computer is given the following IP settings so that the computer matches the
same IP range as the switcher.

3. Now install the supplied SE-1200 MU controller software to the computer.

11

3.2 Installing the SE-1200 MU Controller Software to a Windows Computer

The SE-1200 MU can be connected to a simple IP network and controlled using Windows-based software. If
you have not already set up the SE-1200 MU with a computer then please follow the instructions on the
previous page.

The SE-1200 MU comes with an accessory software CD. If this CD has been lost or has not been supplied
then please download the latest software from the Datavideo SE-1200 MU web page. See:

www.datavideo.com

The install executable file [.exe] will be called SE1200 Control v.x.x.x.x
The v.x.x.x.x represents the latest version number.

Double click this .exe file then follow the on screen install wizard prompts.

Once installed launch the SE-1200 MU controller software.

The SE-1200 MU controller software has a built-in IP finder, which is designed for PC with multiple Ethernet
cards or DHCP network environment. Please note IP finder can only find devices that are on the same
network domain as the PC. If you cannot remember your device IP, please contact your local Datavideo
distributor for assistance as there is currently no reset function for network settings. Upon launch of the
SE-1200 MU controller software, you will be prompted to select one Ethernet Interface Card.

Once selected, click OK to start the scanning process.

If the SE-1200 MU control software cannot find the SE-1200 MU device, the software will continuously
prompt you for an appropriate interface card. Again, please make sure the selected interface card is on the
same network domain as the SE-1200 MU device.

Once the SE-1200 MU device is found, the software will connect with the switcher hardware over the IP set
up described on the previous page.

12

As the program buttons are clicked the SE-1200 MU program output and multi view output will show
changes.

3.2.1 Router Based DHCP Setup

The computer software can also access and control the SE-1200 MU over an existing TCP/IP LAN type
network. In order to initially set up the SE-1200 MU, you may need the assistance of your local I.T.
specialist to help with the network settings. To help guide you, we have included a simplified network set
up example below, further advice may be available through your dealer locally or your Datavideo regional
office.

To create this simple dedicated SE-1200 MU IP network you will need:

• An IP router which can assign/give IP

addresses.

• Two RJ-45 patch leads.

• Windows 7/8/10 laptop or PC.

• The IP router Administrator login and

password.

• The Datavideo SE-1200

MU controller software.

13

Instructions

1. First connect the router to the SE-1200 MU and the Windows computer using two RJ-45 patch leads.

2. Turn on the Windows computer and set it to DHCP setup within the Windows Network and Sharing

Centre.

3. Now click the Windows start button and run the CMD prompt window.

4. At the command line > : _ type IPCONFIG and press enter.

5. The DEFAULT GATEWAY number displayed should be the router’s current IP address.

6. Enter the DEFAULT GATEWAY IP address into the address bar of the computer’s web browser.

7. The web browser should display the login window for the router. Enter the router’s login and/or

password.
The login details may be written on a sticker on the router itself or noted in the manual for the router.

8. Once logged into the router we need to change the router to supply IP addresses in the

192.168.100.xxx range. Use the router’s LAN Setup or Configure LAN option to set the router’s IP
address as 192.168.100.1 and click save / apply.

9. Now reboot the router and power ON the SE-1200 MU.

10. Log into the router again using the web browser and the router’s new IP address 192.168.100.1

11. Use the router’s LAN Setup or Configure LAN option again, within this option there should be another

option called Address Reservation or Client List.

12. The two devices connected to the router should be listed here, the computer and the SE-1200 MU.

13. The computer, because it is set for DHCP, will already have an IP address automatically assigned to it in

this list.

14. The SE-1200 MU may only show its MAC address (1E:ED:19:27:1A:B3). Copy and Paste the SE-1200

MU’s MAC address into the MAC address reservation box. Now enter the following IP address

192.168.100.101 into the reservation box next to the SE-1200 MU’s MAC address.

15. The router should now give the IP address 192.168.100.101 to the SE-1200 MU when it is connected to

the router.

16. Click save / apply then reboot the router again.

17. Close the web browser and CMD windows.

18. Now install the supplied SE-1200 MU control software to the computer.

3.2.2 How to control the SE-1200 MU from another building or city

Once you are familiar with the SE-1200 MU you may want to control the switcher from another building or
even a different city. This requires certain internet and network access that may not already be present at
both sites.

Note: It is best to discuss your planned SE-1200 MU set up beforehand with your local I.T. or network
support manager as this process will involve ‘opening’ or ‘forwarding’ TCP/IP ports.

To create this dedicated SE-1200 MU IP set up you will need:

• Two sites with internet access. We will call these site A and site B.

• Site A will have the same SE-1200 MU set up as Section 3.1 but with no local computer connected.

• Site B will have a Windows 7/8/10 computer connected to the internet with VLC Player and the

Controller software.

• Port 5000 will allow streaming of the SE-1200 MU multi view from site A to VLC Player at site B.

14

• Incoming commands on Ports 5003 and 5004 at Site A will be port forwarded to the internal

private IP address of Datavideo SE-1200 MU at site A to allow control from site B.

• The Public IP address for site A needs to be discovered, this will be used as the Target IP address

for both VLC player and the SE-1200 MU Controller software at site B.

3.2.3 Setting the Target IP Address with the Controller Software

Click Setup in the MENU SELECT panel and the current IP Network settings are shown alongside the
software version.

15

If the network settings are wrong then you may not be able to control the SE-1200 MU. Always keep a note
of the last IP settings used and change these settings carefully to avoid problems.

Target IP address – This IP address is the location on the local network, or the internet, where the software
can talk to the SE-1200 MU. By clicking on Target IP address you can enter a new address, once entered
click Save Setup. The next time the software controller is opened, it will try to contact the switcher on this
new Target IP address.

Network – This option in the yellow menu column allows you to change the network options on the SE­1200 MU. When delivered from the factory the default static IP settings should be:

Set up: Static (a manually set IP address that does not change even after power cycling the SE-1200
MU unit)

IP address: 192.168.100.101
Subnet Mask: 255.255.255.0
Gateway: 192.168.100.1

DHCP set up - If the IP set up method is changed to DHCP then each time the SE-1200 MU is started, it may

be given a different IP address by the network. Only use this method if you know how to find the SE-1200
MU on the internal IP network. A device on the network (usually a router or server) will automatically give
a spare or fixed IP address to the SE-1200 MU. The other settings such as IP address, Subnet Mask and
Gateway may appear blank within the controller software as these would be automatically set by network
router/DHCP server.

16

Chapter 4 SE-1200 MU Video Setup

4.1 SE-1200 MU Multi View Output

The SE-1200 MU multi view output can be supplied locally, from either the HDMI1 or SDI outputs 1 and 2
on the units rear panel, see section 2.2 (Chapter 2). The multi view can also be streamed over a
LAN/internet connection, see section 3.2.2 (Chapter 3).

The default multi view output, when new, is from HDMI output 1. This HDMI output operates at 1080P,
720P or 1080i depending on the video standard chosen, see section 4.3 (Chapter 4).

The Multi view shows monitoring images for Preview (PVW), Program (PGM), Inputs 1~6, as well as SDI
outputs 1 and 2.

The SE-1200 MU can also show audio level bars overlaid on the Program image within the multi view. This
confirms if analogue XLR audio input is being received and embedded to the selected Program output(s).

A Red tally indication box is shown around the selected Program source(s). This video image is also seen at
the switchers selected Program output(s). A Green tally indication box is shown around the selected
Preview source. This will be the image source to be mixed to, wiped in, or cut to next depending on the
user’s preference.

Images SDI out 1 and SDI out 2 confirm what is being sent from those SDI outputs. These outputs can be
configured differently by the user, see section 5.2.1 (Chapter 5).

17

4.2 Setting the Video Outputs

SDI 1 Factory default – Program out

1: Multiview

2: PGM Out

3: PVW Out

4: PGM DSK1

5: PVW DSK1

6: Clean PGM

7: Clean PVW

8: Input 1

9: Input 2

10: Input 3

11: Input 4

12: Input 5

13: Input 6

These rear panel video outputs are initially set as follows when shipped from the factory.

SDI 2 Factory default – Program out
HDMI 1 Factory default – Multi view output

Each of the outputs can be reconfigured to one of the settings below by using the menu option Outputs

HDMI 2 Factory default – Multi view output

Note: Ensure at least one output is left set as Multi View so the Main Menu can still be accessed.

4.3 Setting the Video Standard

The SE-1200 MU video standard can be
changed by using the menu path SETUP >
STANDARD.

The SE-1200 MU is initially set up for the
1920 x 1080 i50 or i60 video standard when
shipped from the factory depending on your
country’s video standard.

As with most HD video switchers, the SE­1200 MU will expect all video inputs to be
operating at the same video standard as the
switcher itself. If a connected device is
supplying a different video format/standard then the switcher may not display the video for that input.
Change the source equipment settings to match the switcher’s video standard or vice versa.

The SE-1200 MU can support the following HD video standards: 1080i/50, 1080i/59.94, 1080i/60 and
720p/50, 720p/59.94, 720p/60.

18

4.4 SE-1200 MU Video Layers

The SE-1200 MU has four dedicated keyers, Key1, Key2, DSK1 and DSK2. All four

by the user

for an example of keyer

The SE-1200 MU is a High Definition Digital Video Switcher and as well as mixing video sources and
embedding analogue audio, it has additional functions such as Picture in Picture (PIP), Chroma Key, Luma
Key and Down Stream Key (DSK).

Before attempting to use the SE-1200 MU’s PIP, Chroma, Luma and Down Stream Keying functions, it may
help to first understand the order of the video layers at the SE-1200 MU Program outputs.

The background video layer is used for transitioning between Preview and Program sources. This layer also
includes any selected wipe transitions. This layer can be hidden or partly hidden by the PiP, Keyer or DSK
video layers in front of it.

The Key 1 and Key 2 layers can be used for PiP, Chroma, Linear or Luma Key applications. The KEY video
signal (foreground) is shown in this layer and the FILL video signal is displayed in the background video
layer. If set up incorrectly, these key layers can stop the video behind being displayed.

The Picture in Picture (PiP) feature of the Key 1 & Key 2 layers can be used for displaying a smaller
secondary image in front of the background video layer. This smaller PiP image can be resized, cropped,
repositioned and even keyed by the user to avoid an important part of the background video layer being
covered by it.

keyers can be active simultaneously. Key 1 and Key2 can be set as Upstream or
Downstream keyers.

The Layer priority, or order, of Key 1 and Key 2 can also be changed
using the Priority button in the Transitions Control area. DSK 1 & DSK 2 can only be
used as Downstream keyers. See the diagram above
layering with the SE-1200 MU.

The Down Stream Key layers (DSK 1 & DSK 2) are placed on top of all the previous layers. These layers are
typically used with Character Generator inputs for displaying titles, graphics, lower thirds, clocks and logos.
Datavideo offer several Character Generator products (additional purchase) such as TC-200, CG-250, CG­350 and CG-500. If set up incorrectly these DSK layers can also stop the video layers behind them being
displayed properly.

Click a crosspoint (lower row) then click again on
the required input (upper row) to link them. The
example above shows inputs 2 and 3 swapped.

5.1.2 Source Labels The multi view source labels can be changed. First click Inputs menu then choose the input you wish to name. Then use the pop up keyboard to edit the selected input name. Press Enter to store the change, the

new Multi view label should now be displayed.

Note: The label will accept up to 16 characters but only the first 10 are displayed.

A Freeze option is provided for use when you wish to grab and save a still image from a selected input, see

Stills – Grab and Save section.

A ProcAmp option is provided for adjustment of an input’s white, black or chroma level. It may be easier or
better to adjust an incoming image at the source equipment, please seek advice before changing these
settings.

5.2 Setting up the SE-1200 MU Video Stream Based Multi View

The SE-1200 MU is able to send, or stream, its multi view image over the same IP network connection used
for controlling the switcher. This allows the user to see the multi view on the same computer that is
remotely controlling the switcher.

21

This streamed multi view can then be viewed using a third party software application called VLC Media
Player, version 2.1.5 or later is recommended. To download the latest free version of VLC Media Player
please visit http://www.videolan.org/

5.2.1 Preparing the SE-1200 MU Stream Output First click the OUTPUTS menu button in the SE-1200 MU software control interface. Then select the STREAMER option in the yellow menu panel on the left hand side. The user can now select the size of the

multi view being streamed. Options are Full, Half, Quarter and Sixth.

By choosing HALF instead of FULL you are using less bandwidth to support the multi view stream being
sent across the IP network.

Reducing the size of the multi view stream may also help overcome delay/latency issues over the network.
Click Stream Start then open VLC Media Player on the computer. Click Media on the VLC menu bar and
navigate to the Open Network streaming settings.

Enter the stream URL as tcp://192.168.100.101:5000 and click Play. The Multi view stream will now be
displayed in the VLC window.

Note: The streamed SE-1200 MU multi view is video only, no audio is sent over this IP connection.

22

5.2.2 VLC Media Player - Stream Caching

The stream caching feature within VLC media

is there to allow enough time for the data

may be unacceptable but this value can be changed

Note: The VLC caching value and multi view stream size are also related to latency. Reducing the SE-1200
MU streamer size may also help reduce the multi view delay or latency across the IP network. The quality

The VLC media player window (with SE-1200 MU multi view) can be displayed on a second computer
monitor using the Windows extended desktop feature. The main computer screen can then be used for the

being received to be converted to a stable or
smooth video feed.

The default caching value is a 1000ms (milliseconds)
or 1 second. This delay behind the live performance

and the delay reduced.

If sending the stream over an office network or
LAN, this caching value can be reduced to around

50ms. If the video in the multi view is unstable then
slowly increase this caching value in 50 or 100ms
steps until you have a smooth video feed.

of the multi view image will also be affected by these settings.

SE-1200 MU control panel software.

5.2.3 Port Forwarding for the SE-1200 MU

So that the SE-1200 MU Multi view stream can be seen and the unit can be controlled over the internet (or
beyond the default gateway), certain ‘ports’ should be opened on your network firewall or gateway device.

TCP port 5000 is used for the VLC based multi view stream. Ports 5003 and 5004 are used for controlling
the switcher. These three ports should be forwarded to the SE-1200 MU internal private IP address.

Your local network administrator or I.T. support should be able to help you with this. For further
information please see Chapter 3 Network Setup.

23

Chapter 6 PC Control Panel

6.1 Sources Panel

This panel on the SE-1200 MU control software consists of three identical rows of buttons and is used to
assign sources or select images for Program or Preset outputs. The buttons are labelled from left to right as

Black, sources 1 to 6, and Bkg.

6.1.1 AUX BUS

This row of buttons is typically used to assign sources for the setup of the PIP, Linear, Chroma and Luma
Keyer functions. If a keyer or PIP function is active/ON then the selected AUX button will be backlit red.

6.1.2 PROGRAM

This row of buttons is typically used to select sources or images for the SE-1200 MU main Program output.
The currently selected source being sent to the Program output will be backlit Red. Simple cuts between
sources can be performed on this row by clicking on the source number required for the next shot.

6.1.3 PRESET

This row of buttons is typically used to select sources or images for the SE-1200 MU Preview output. The
currently selected source will be backlit Green. The selected button on the Preset row will change from
Green to Yellow during Preview-Program transitioning using T-Bar.

6.2 TRANSITION CONTROLS Panel

6.2.1 Previewing a Selected Transition/Wipe

It is possible to see, or test the effect, of a selected transition in the Preview output before applying it to
the Program output. In our example below we want to test a selected wipe. Input 1 is being sent to
Program and Input 2 in Preview will be shown next.

24

Using the TRANSITION CONTROLS panel click to select the Trans Pvw button (back lit green is ON). Next

select and apply the transition or wipe that you would like to test on the Preview monitor.

You may also notice that the Preview Monitor changes to show the currently selected Program source
(Input 1). Do not worry, the selected Preset source (Input 2) has not changed. Click the Auto button
(TRANSITION panel) or move the T-Bar manually to preview the selected transition. You will now see the
previewed transition between input 1 and input 2 using the selected wipe. Importantly this is only shown
on the Multi view and Preview outputs but has not been shown on the Program output.

NOTE: Remember to disable the Trans Pvw button before attempting to use the selected transition on
the live Program output.

6.2.2 Rev and Nrm (NORM) / Rv (REV) Buttons

When the Rev and Nrm / Rv buttons are both OFF, the selected WIPE transition will operate in its default
direction only.

When the Nrm / Rv button is ON, the selected WIPE transition
will automatically switch directions as each transition is
completed.

The Rev button will switch on and off automatically

to indicate the direction of the next transition.
When the Rev button is ON then the selected transition will
operate in the reverse direction only.

6.2.3 Key 1 & Key 2 PRIORITY Key Function

The PRIORITY button toggles the layer order or priority of Key 1 & Key 2.

When Key 1 and Key 2 are both active in Preview (or Program),
they may overlap each other on the screen. Using the Priority
Button you can change the order of these keyers. The button acts
in a toggle on/off way, i.e. Key1 over Key2 or Key2 over Key1.

NOTE: It is best to check and change the Priority of Key 1 and Key

2 when they are initially active on the Preview monitor/output.

6.3 Transition Effects

The SE-1200 MU allows the user options for cutting or transitioning between the selected preset and
program video sources.

7.1.2 Keyer Matte

1. The Colour Palette allows selection of a colour for the Keyer Matte.

2. Click on the Colour Palette and the crosshair will move to display the currently selected colour where

the mouse pointer was located. The selected colour RGB values will also be shown to the right.

3. The Luma value determines how bright or dark the selected colour or hue is. The Luma can be

adjusted by clicking on the Luma value and using the pop up keypad to enter the new value.

4. The Sat or Saturation value moves the crosshair from the center of the colour palette to the outer

edge. The Sat value can be adjusted by clicking on the Sat value and using the pop up keypad. If the
Hue angle is set to 180 degrees then the Sat value determines how much Cyan is in the matte.

5. The Hue parameter moves the crosshair around the colour palette in the clockwise or anti-clockwise

direction. The Hue value or angle can be adjusted by clicking on the Hue value and using the pop up
keypad.

Certain colour hues can be found at certain angles on the colour palette. For example, Red is 0
degrees (12 o’clock position), Green is approximately 120 degrees (4 o’clock position) and Blue is
approximately 240 degrees (8 o’clock position).

For Luma key purposes using zero values for Luma, Sat and Hue will allow a black keyer matte to be
chosen as above.

A white keyer matte can be created from Luma 100%, Sat zero and Hue zero.

7.2 Linear key - Quick DSK 2 Setup

Note: The DSK 1 and DSK 2 keyers can only be used for Linear or Luma keying. Chroma keying is not

supported on DSK 1 and DSK 2.

In this downstream keying example, we are supplying the SE-1200 MU with a live video signal on input 2,
this is selected on the Program and Preview rows. We have also connected a CG-350 Character Generator
(separate purchase) which is supplying separate KEY and FILL signals to inputs 5 and 6. These two CG-350

Chapter 8 CHROMA Key Functions

8.1 Overview

The Chroma Key feature of the SE-1200 MU is
easy to use. Typical Blue and Green screen
studios can be quickly incorporated into an SE­1200 MU production.

The following is a quick overview of Chroma Key
basics.

The camera, backdrop and lighting all play an
important role in producing the optimal
Chroma Key result. Although the SE-1200 MU is
equipped with excellent keying controls, it is
best to start with a good keyable image.

A good foreground image helps produce a good key

Three chip/Three sensor camera

We strongly recommend the use of a three chip or three sensor camera for Chroma Key shooting. If the
camera has three chips or sensors then this usually means good colour separation within the camera. The
optics on these cameras are usually better too. The extra image clarity and the good colour separation help
improve the quality of the subsequent keying with the camera’s output.

White Balance the Camera

White Balance is extremely important after setting up a chroma key studio. The camera must be correctly
white balanced to minimize the subject picking up any colour cast (green or blue) from the
background. Of course the white balance settings will vary according to the type of lighting you are
using, but neutral whites and good skin tone colour are the all-important targets.

To set the white balance you will need a white reference card (or a sheet of white paper). Focus the
camera on the reference card and light it evenly using the main light. Set the camera’s iris / aperture so
that the card is correctly exposed. Use the Auto White Balance (AWB) function, or set the white balance
manually so that the card appears white. If you are in any doubt about how to white balance your camera,

please refer to your Camera’s instruction manual for more details.

Lighting

Lighting of your chosen green or blue backdrop is extremely important; the more even the lighting on the
backdrop the better the finished result. Lighting setups for the foreground subject will vary according to
the effect that you want. For chroma keying backdrops, balanced even lighting, with no hotspots or
shadow areas is the aim. The easiest way to achieve balanced Chroma key lighting is with a lighting setup
that looks similar to this:

42

In the diagram, you will see that we recommend a minimum of four lights and we keep the subject more
than 1m away from the backdrop. It is always easier to get more even lighting if the subject is farther
away from the backdrop (no shadows). The foreground lighting on the subject will also vary according
to the effect that you are looking for.

8.2 Chroma Matte

This matte sets the center of colour
range that will be used for keying.

The Chroma Matte parameters and the
values are shown along the bottom of the
display below.

The Hue can be changed by clicking on
and dragging the crosshair around the
colour palette with the mouse pointer.
The Hue value can also be finely adjusted

by clicking the Hue degree value in the lower bar and entering the required number.

Certain colour hues can be found at certain angles on the colour palette. For example, Red is 0 degrees (12
o’clock position), Green is around 120 degrees (4 o’clock position) and Blue is approx. 240 degrees (8
o’clock position). Secondary colours such as, Yellow at 60 degrees, Cyan at 180 degrees and Violet at 300
degrees.

The Luma value relates to how bright or dark the selected key colour or hue is. The Luma value can be
adjusted by clicking the Luma Function value and entering a new value. The Bgnd Suppress or Background
Suppress Control is used to remove the Luma (brightness) of the background from the final image. If the
Chroma Key Output is showing Light Edges, then the Bgnd suppress can be used to suppress any

43

background Luma that is showing through on these edges.

The Opacity setting affects how transparent the foreground Chroma matte is.

8.3 Chroma Key Ctrl

The Chroma Key Ctrl parameters and
values are shown along the bottom of the
display. Two colour palettes, Main and
Chroma, are shown in the diagram.

The Main palette corresponds to values of
Key Acceptance and Key Lift. The Chroma
palette corresponds to the Color Spill
settings.

Key Acceptance is represented on the

Main Palette as a sector or area covering a range of hues or colours that closely match the background

colour to be keyed as set in Chroma Matte. The user can start with a value of 120 degrees and this value
can be fine-tuned up or down using the Key Acceptance depending on the setup of the green or blue
screen studio.

Key Lift is represented on the Main Palette as a line extending from the center point in the direction of
the Key Acceptance sector. This value affects the performance of the Chroma key in dark or black areas. If
the dark areas of the video are becoming too transparent, then applying more Key Lift may help
depending on the setup of the green or blue screen studio. This value can be fine-tuned up or down by
changing the Key Lift value.

Key Gain affects the performance of the Chroma key in light or white areas. If the light areas of the video
are becoming too transparent then applying more Key Gain may help depending on the setup of the
green or blue screen studio. This value can be fine-tuned up or down by changing the Key Gain value.

8.4 Color Spill

The Color Spill parameters and values are
shown along the bottom of the display
below. These settings are used to
control/remove any unwanted Chroma or
colour Spill from the background onto the
foreground subject. There are two sectors
drawn on the Chroma palette, one
represents the wider Chroma Acceptance
range and the narrower Chroma Suppress
range.

Chroma Acceptance sets the amount of the available colour range or space that should be Chroma
suppressed. Usually starting with a large value of 120 degrees should produce reasonable results. This

value can then be fine-tuned up or down using the Chroma Acceptance value depending on the setup of
your green or blue screen studio.

44

Chroma Suppress, when set to 0%, removes the hues or colours that lie only on the same axis as the

Chroma Matte Hue angle. This setting has the effect of removing Background colour spill, but keeping the
underlying hue. When set to 100% then all the Chroma values that are ‘captured’ within the Chroma
Acceptance Angle are suppressed to greyscale – i.e. they have their Chroma removed. Usually starting with
a value of 50% should produce reasonable results. This value can then be fine-tuned up or down using the

Chroma Suppress value depending on the setup of your green or blue screen studio.

Saving the Chroma Key Setup. Remember to save your current user setup. In this way, several Chroma

Key setups can be saved to different user memory slots, thus allowing you to switch from a Blue screen
setup to a Green screen setup instantly.

8.5 Chroma Key - Setup

The SE-1200 MU offers two Chroma key channels in the Key 1 and Key 2 Aux buses. In the example below
we will show you the steps for setting up the Chroma key.

previous sections (8.3 and 8.4).

Once you are happy with the Chroma key
settings click the Auto button in the Transition
panel to make the key active in the Program
output.

8.6 Key MASK Function

A simple rectangular garbage mask can be quickly created within the SE-1200 MU. This Mask feature can
be used when the Chroma key or Luma key modes are active.

Note: This mask’s edges are fully transparent during the keying process. This can be helpful if the blue or
green backdrop in a chroma key set up does not occupy the whole foreground shot. It is also helpful if only
a small area of the foreground image is being Luma keyed, say a whiteboard or blackboard. Each mask
value is based on a percentage of the screen width or height, thus 0% indicates no mask edge and 50%
means masking to half of the screen area from the selected outside edge.

Chapter 11 Appendices

Appendix 1: Audio

The SE-1200 MU can only accept external
audio using the analogue XLR inputs on the
rear panel. Ideally a master audio mixer
should be used alongside the SE-1200 MU. A
Datavideo AM-100 audio mixer or AD-200
audio delay unit could be considered.

Changing the Audio Mode option from
Analog to OFF will mute the incoming XLR
audio from the external master audio mixer.

The Audio sub-options for SDI and HDMI
allow the user to individually turn ON/OFF
the audio at the SDI 1, SDI 2 and HDMI 1 outputs.

Audio Level relates to the preferred audio standard for the user. A choice of SMPTE or EBU is given.

Note: Audio is not supplied with the IP streamed multi view. Local SDI and HDMI outputs can provide the

audio.

57

Appendix 2: GPI Out

The SE-1200 MU can control external recorder/playback devices via simple contact closure GPI switch.

The GPI interface is a 3.5mm Jack Socket which is situated on the rear panel of the SE-1200 MU.
Contact closure between the Outer and Inner contacts on the jack plug will trigger a user selected event.
Power is supplied by the SE-1200 MU and is less than 5V DC.

This GPI socket can also be used as a socket to trigger record or playback events with other equipment
such as the Datavideo HDR-70 recorder.

SAFETY FIRST The cabling required needs to be designed specifically to connect the SE-1200 MU to the
chosen record or playback device as they are not all the same. The cabling required can be made by
yourself or a competent technician. Please speak with your Dealer or local Datavideo office to get further
help and advice.

Outputs Menu

This allows the user to perform GPI
configuration.

After turning On the GPI Enable, select the GPI
Mode, which is either set as Level or Pulse. The
GPI signal Width can also be configured by
setting a value (1~9).

The GPI out can then be assigned to one of the
inputs 1~4 under Source. When the selected
channel/source is taken to the Program output
the GPI signal is triggered. A GPI Delay can be
set between 0 and 99.

This feature could be used to trigger playback from units such as the Datavideo NVP-20 or HRS-30 or HDR-
60/70.

Appendix 4: Firmware Upgrade

From time to time Datavideo may release new firmware to either add new SE-1200 MU features or to fix
user reported bugs in the current switcher firmware. Customers can update the switcher firmware
themselves if they wish, or they can contact their local supplier or Datavideo office for assistance, should
they prefer this method.

This page describes the firmware update process, and it should take approximately 15 minutes total time
to complete.

Once started the update process should not be interrupted in any way as this could result in a non-
responsive unit.

As well as a working SE-1200 MU switcher you may need:

 A Windows 7/8/10 PC/Laptop
 The latest Control Panel program for the mixer. This can be obtained from your local Datavideo

office/supplier.

 A simple router IP network/Static IP set up, see example on Section 3.2.1.

Firmware Update Procedure

1. Install the latest SE-1200 MU Control Panel program on the Windows PC/Laptop.

2. Locate the Ethernet port on the rear panel of the SE-1200 MU and connect the Ethernet port to the

router.

3. Open the SE-1200 MU Control Panel program.

4. Locate and click the Setup button in the MENU SELECT Panel.

5. Click the Software Upgrade option in the yellow menu column.

6. Click the Upgrade Processor option in the lower menu row, the upgrading notification will appear.

7. Wait for the SE-1200 MU to complete the upgrade process, the upgrade notification will disappear.

8. Restart the SE-1200 MU device. Note: The update may reset the IP address to the factory defaults,

see Section 3.2.1.

9. Restart the SE-1200 MU Control Panel program on the Windows PC/Laptop.

10. Go to the Setup Menu again to confirm the FW version has updated and that control is still working.

11. Once control is working, load a USER memory to quickly return to your preferred SE-1200 MU

setup.

Appendix 5: How to Connect RMC-260 to SE-1200 MU

RMC-260

SE-1200MU

The user is allowed to connect a physical switcher controller keyboard to the SE-1200 MU. An example of
the controller keyboard is the RMC-260, which communicates with the SE-1200 MU using RS-232 interface.
The diagram below illustrates the physical connection between the two devices.

The table below provides details of RS-232 PIN definition on the device end, which is a female connector.

The user may establish the RS-232 connection between RMC-260 and SE-1200 MU using a male-to-male
cable with the wiring scheme as depicted in the diagram below.

61

Note: All panel buttons will be backlit in white LED light after the RMC-260 is powered ON. As soon as
the RS-232 connection is established, buttons will be backlit in its state color LED light. After the RS-232
connection is disconnected, it takes approximately 2-3 seconds for the RMC-260 panel buttons to return
to white color.
