Tdeint Full=False

[futurex]

Hello,

from the tdeint readme:

full:

If full is set to true, then all frames are processed as usual. If full=false, all frames
are first checked to see if they are combed. If a frame isn't combed then it is returned
as is. If a frame is combed then it is processed as usual. The parameters that effect
combed frame detection are cthresh, chroma, blockx, blocky, and MI. Full=false allows
TDeint to be an ivtc post-processor without the need for hints.

true - normal processing
false - check all input frames for combing first



i would like to know whether full=false in tdeint will give any advantage on pure interlaced sources?

my understanding is that it should be set to FALSE on sources that contain both interlaced AND progressive, so that the progressive parts don't get deinterlaced.

but what about pure interlaced sources? it checks frames for combing first, and if no combing, the frame is returned as is. is this better than tdeint at a good threshold? is an unprocessed frame(that doesn't show combing) better quality than tdeint processing it? is it OK to use it on pure interlaced sources?

thanks! ;)

Maybe for animation. For real life footage, the camera and scene both have to be perfectly still for stretches to make the option useless, plus you run a danger of it not catching very lightly combed frames (but more obvious to people) that it should be deinterlacing.
