RE: Problems with bitrate in the latest version of the program - Selur - 27.01.2022
Made a dev version which should fix the issue, send you a link via pm.
As side notes:
- you workflow seems borked.
You deinterlace to 29.97fps and thus throw away potentially half of the motion data.
Then you interpolate to 59.94 which requires to guess the motion data you through away.
Either:- if your source is telecined (do not trust the source flags, look at the content properly!, at least comercial DVDs are nearly always telecined and not interlaced)
You should ivtc to 23.976 and then interpolate to your target frame rate.
or
- bob deinterlace from 29.97 to 59.94 and thus avoid unneeded interlation artifacts. (and be faster with the processing)
- if your source is telecined (do not trust the source flags, look at the content properly!, at least comercial DVDs are nearly always telecined and not interlaced)
- Why are you using Avisynth? Vapoursynth should be a faster.

I tested the version from the PM link - is working correctly

Thanks for the feedback, happy that worked.

I do not do this. I have japanese dvds with NTSC and 29.97fps

I want to smooth the image

Quote:I do not do this. I have japanese dvds with NTSC and 29.97fpsand by doing a same rate deinterlacing you throw away half of the motion information,...
What QTGMC does is interpolate each field to a frame and thus creating 59.94fps content, by not using bob-mode half of those interpolated frames are dropped.
