In the same way that deinterlace and deinterlace_bob are short-cuts for yadif settings, I would like to see a short-hand to optionally remove yadif from the Producer altogether.
CasparCG doesn't support PsF. If you create a Progressive channel and ingest PsF content on a Decklink input, it appears as 1080i5000 and Caspar automatically applies a deinterlacing filter. If you provide your own yadif options you can override the hard-coded yadif filter but there appears to be no option to remove the filter altogether.
If the above short-hand was implemented, CasparCG would support PsF input on a Progressive channel.
