Testing Capture and Playback
It's a good idea to run a quick test to ensure you can capture and play back video before you need to use
your Teranex Processor hardware for anything important:
Connect a video monitor or TV to the video output of your Teranex Processor. An HDMI TV is
very convenient for this test as both video and audio can be monitored without needing external
audio connections.
Connect a video source to the video input of your Teranex Processor, especially a camera or
deck. DVD players shouldn't be used for this test as they typically have copy protection on their
HDMI and analog outputs so you won't be able to capture from them even if you're using home
made DVD's.
Use the buttons on the Teranex Processor to set your video and audio connections for input
and output.
Launch Blackmagic Media Express.
Video Playback test using Blackmagic Media Express
Import a test clip in to Media Express. If you see a message that the selected video format is not compatible
with the current project, click "Don't save" to discard the current project and create a new project for
the test clip.
Double click the test clip and you should see the video on the monitor connected to the output of your
Teranex Processor. Audio output can also be monitored.
Video Capture test using Blackmagic Media Express
Go to Media Express>Preferences on Mac OS X or Edit>Preferences on Windows.
Select a project format which matches your converted video output rather than the source video.
Choose a capture file format.
Set the storage location for your captured video and audio and choose whether to stop capture
or playback if dropped frames are detected. Choose a compressed capture file format so you can
capture to any disk.
Close the Preferences and click on the Log and Capture tab. You should immediately see your
converted video source in the video preview pane of Media Express.
Click Capture to perform the capture test. Click Capture again to finish the test. Double click on
the captured clip in the Media List to play it back on screen and on the outputs of your Teranex
Processor hardware.
Detailed information about using Media Express is included later in this Capture and Playback chapter.
Connect a video monitor and source to your Teranex Processor.
