Playback always seems to be yuv422 for SDI 4K

PostThu Oct 12, 2017 2:52 pm


Apologies if this has already been asked before, I tried searching and couldn't find anything.

When playing back from the DeckLink SDI 4K, the output always appears to be yuv422, even though I've set the playback to something like rgbx10 (including performing the relevant conversions). I found this out when I was feeding the output of the card directly back into the input, the auto input detection was always picking up the signal as yuv 422, and playing it back correctly.

Is there an automatic conversion that happens somewhere? and is this a card specific thing? If so, is there a way to configure this somewhere so that this conversion doesn't occur?

Thanks in advance for your help
