What makes you and Warperus think so?
I know in some very old threads here on doom9 it is considered correct to use interlaced chroma upsampling for YV12 sources which were enconded as interlaced even if they are progressive (no visible interlacing, the two fields create one progressive frame).
And while that is not "wrong" I'm fairly certain the optimal way is to use progressive upsampling whenever there is no visible interlacing, regardless of how the source's YV12 chroma was downsampled from YUY2 or whatever it was.
I would like to know what some of our chroma experts think about this. Gavino?
