Deinterlace only the frames flagged as interlaced

[Ichirare]

Hi,

Firstly, thank you for your software. It allows to utilize the power of VapourSynth and AviSynth in a nice and convienient way.

I'm trying to remove interlacing from a mixed (PsF with some sections being truly interlaced) content. I suppose Field Matching is the best to find progressive frames and interlaced frames and decode them as such. But the problem is with processing them. I obviously want to leave the progressive frames untouched by deinterlacer. Many deinterlacers, found in for example ffmpeg, allow the use of a flag to indicate that I want to deinterlace only those frames, which were flagged as being interlaced.

Is that possible in Hybrid? I tried the TFMBob deinterlacer in VapourSynth, but I'm not sure it's doing it right? Is it possible with QTGMC?

Thank you
