Compressed Clips Supported Resolutions:
Broadcast Pix currently supports Compressed Clips exported as Quicktime .mov with the following codecs:
- DV/DVC Pro
- h.264
- Apple ProRes*
It is possible that other Compressed Clip formats such as MPEG4 may play correctly, but they are not supported by Broadcast Pix and can cause unexpected behavior from the system. We strongly recommend that you use only the supported resolutions above.
*Apple ProRes codec only available from Mac platforms. Windows based video editing software cannot export using this codec.

HowTo: Exporting Compressed Clips (No Alpha Channel)
The internal clip store of the Slate G Series system can support playback of standard definition and high definition compressed clips. Non-G Series system can only support standard definition clips. This is ideal if you are exporting video files from a non-linear editing system like Avid or Final Cut Pro or even an animated background from Adobe After Effects or Apple Motion. Alpha channels with compressed clips are not supported, to import an animation with an alpha channel you need to export it as a 32 bit Targa image sequence.
Export your files out of your 3rd party software with these settings:
- Standard Definition
- File Size: 720x486/NTSC or 720x576/PAL (4:3 or anamorphic/widescreen at 1.2 pixel aspect ratio 16:9)
- Frame Rate: 29.97/NTSC or 25/PAL
- Field Order/Dominance: Bottom/Lower first/NTSC or Top/Upper first/PAL
- Scan Mode: Interlaced
- High Definition
- File Size: 1280x720p or 1920x1080i
- Frame Rate: 59.94/50 or 29.97/25
- For QuickTime movies:
- Video Compression Settings: DV/DVCPro 25 Mbps, H.264 or ProRes
- Quality: Best
- Audio Settings: Stereo PCM Data, 16 bit, 48kHz (or any sample rate)
- File Extension: .mov
Step-By-Step Export Procedures for Final Cut Pro:
-
 On your Final Cut Pro computer, select the File drop down menu.
Select Export->Using QuickTime Conversion
 A Save pop-up window will appear. Under Format select QuickTime Movie from the drop down menu, then select the Options button.
 The Movie Settings menu window will appear, select settings under the Video section, to change the video compression settings.
In this same window, make sure that both Video and Sound headings are checked to ensure proper exporting of both audio and video.
The Prepare for Internet Streaming section may be unchecked, although this setting has no effect for playout in Broadcast Pix.
- The Standard Video Compression Settings window will appear, as shown below. In this window you will be able to change the Compression Type (either DV/DVCPro 25 Mbps, H.264 or ProRes), the Quality, Scan Mode, and Aspect Ratio.
 Select the Compression Type drop down menu, which will bring up a list of possible compression settings.
Select either:
- DV-PAL
- DV/DVCPRO-NTSC
- DVCPRO-PAL
- H.264
- ProRes 422
- ProRes 422 (HQ).
Choosing any other setting will not create a file recognizable in Broadcast Pix.- Under the Motion section, select a Frame Rate drop down menu and select 29.97/59.94 for NTSC or 25/50 for PAL.
- Under the Compressor section, select Best with the Quality slider.
- Under the Scan Mode drop down menu, select Interlaced.
- Under the Aspect Ratio drop down menu, select either 16:9 or 4:3 to preserve the native aspect ratio of the clip.
- Once all these settings have been selected, click on OK.
- Under the Movie Settings window, select Settings under the Sound section, to change the audio compression settings.
- The Sound Settings window will appear, as shown below. Under the Format drop down menu, select Linear PCM.
- Under the Channels drop down menu, select Stereo (L R).
- Under the Rate field, select 48.000 kHz from the drop down menu. The clip store will support any audio sample rate, since it automatically converts all audio to 48.000 kHz.
- Under the Render Settings section, select Best under the Quality drop down menu.
- Under the Linear PCM Settings section, select 16 bits under the Sample size drop down menu.
- Click on OK once all these settings have been selected.
- In the Movie Settings menu, click on OK to save all your video and audio settings.
- In the Save window, name your file in the Save As: text field and choose a destination to save the file in the Where: drop down menu.
- Click on Save to export and save your QuickTime move.
No Video on Clip Ingest
I’m using the Clip Store Ingest, but I don’t see the correct input when I ingest (record) a clip?
For Slate 100 and Slate 1000 switchers, select your input to record
from the drop-down menu in the Clip Ingest tool. Those inputs
correspond to where on the input cards those sources are plugged into,
not where on your switcher you’ve assigned them in your show.
For Studio 2000 and Slate 2100, 3000, and 5000 switchers, once in
the Clip Ingest tool, put your panel into fail-safe mode. Select the
Capture/Controls button, and then select the source you want to capture
in the source row (not the program row, but the one above it). Remember
that in fail-safe mode, the sources correspond to where the inputs are
plugged into the router or iBoB, not where on your switcher you’ve
assigned them in your show.

No Audio on Clip Playback
I can't hear audio out of my clips.
First confirm that you can hear audio out of the system. All
systems ship with a file called "ingest_test" that consists of color
bars and tone. Add that clip to your show, select it in Clips 1 and
bring to program. You can confirm that it is playing by seeing the clip
counter moving. You should then be able to monitor the audio output of
Clips 1 left and right channels of the system. Check the signal flow of
your audio chain from out system outputs and confirm the tone signal.
Then check any clips you have ingested or brought into your system.

Upgraded Quicktime
I upgraded to the latest version of QuickTime, and now I’m having problems in my Clip Store.
We are now shipping our switchers with QuickTime 7.5.5 to support playing of
compressed clips. Other versions of QuickTime can cause conflicts in
playing back clips (both compressed and uncompressed). If you have
upgraded QuickTime to a version newer than 7.5.5, remove the newer
version of QuickTime, and reinstall QuickTime 7.5.5.
That version can
be found online here:
http://support.apple.com/downloads/QuickTime_7_5_5_for_Windows
If you have an older version of Quicktime, you can upgrade to version 7.5.5 as long as you are runnig the most current version of the Broadcast Pix Software (found in out Downloads section).
We also recommend turning off auto updating for QuickTime. You can do
this in QuickTime by going to Edit > Preferences > QuickTime
Preferences > Update and unchecking the checkbox for Updates
Automatically.
