Hi guys,
I’ve had the chance to try out all 16 modes…

I only got video from modes 9 and 12
[decklink @ 0x7f94b081ba00] 9 1920x1080 at 30000/1001 fps
[decklink @ 0x7f94b081ba00] 12 1920x1080 at 30000/1001 fps (interlaced, upper field first)
what is the effective difference between interlaced and non-interlaced, in terms of the resulting video file? In terms of streaming, also…?
thank you
Ricardo
