I have some videos that are (blatantly) interlaced, yet no matter what manner of configurations I try to get my media player(s) to deinterlace, they just won't do it. I've tried all manner of configurations between the players and Catalyst Control deinterlace settings.
After checking the OSD of the playing clip, it says "deinterlacing off (says bitsream)". With my lacking knowledge in the process of interlace-detection, I assumed that to mean that there's some type of flag embedded in the video clip that's telling the render that it absolutely doesn't need deinterlacing. Thus, the detection algorithm isn't even being activated (which it would surely see that there's a definite need to deinterlace).
I opened up the video's properties in MPC, and sure enough, the scan type for the clip is set to "Progressive". I'm guessing that this is the reason why no deinterlacing is being performed? When I open the clip in VLC and force deinterlacing, the clip looks perfect.
Question -- Is it possible for me to somehow access and edit the clip's setting/flag to change it from Progressive to Interlaced? And if that's not possible, is there some way to get madVR to ignore the flag/bitsetting for clips?
Obviously, I'd prefer if I could change the clip's flag, so as to not have to manually twist madVR's arm to deinterlace specific clips. Surely there must be a way?
And if it would take a re-encode (from h.264) -- Would it be possible to do with no quality loss (well, as infinitesimal as possible)?
