ATEM TS: Chroma Key, embedded audio, closed caption passthrough
on Dec 9, 2011 at 9:19:49 pm

We have the ATEM Television Studio with just-released 2.7.1 software (thanks for adding SD functionality, by the way!). I am having three issues and hoping for a resolution.

The first is with the chroma key functionality, wherein the adjustment of the target hue causes the program video to also shift hue somewhat. It appears that there is always a bit of the fill source bleeding through, despite getting an otherwise clean key. This seems like it ought to be fairly easy to fix... I hope.

Second, it would be extremely helpful to have the embedded audio from whatever source is on the program bus passed through to the output. Perhaps there could be an option to disable the built-in embedding?

Finally, I find that VANC metadata (especially closed captions) do not pass through to the output. While there are ways to get around the audio issue, not passing captioning completely disqualifies this device for many of our applications.

Thanks for whatever assistance you can provide --

-- Jeff
