    It was originally converted from a .ts. Trying to de-interlace it with QTGMC (I have gotten a lot of help from my friend doing this).
    However, the output video is playing in "slowmo" almost. And it stops at ~halfway through, although the time it takes to get there is the same as the length of the source video. I don't understand what is going on. I will post my script as an attachement.

    I searched up a bit and it might be the variable framrate of the source creating issues? I have re-encoded this around 4 times now every time with the same issue. The reason the script says 1920x1080 and the output file this time is 1440x1080 is because I tested changing the resolution if that had something to do with the issue.

    My Script: https://mega.nz/file/C0w3QLwT#N4ObLeGyLPtMisWvr5E5YML0kKkL7AUbChAjocVhJPw

    Its also way at the bottom.

  2. I think that AssumeFPS() at the end cannot be there, to just put assume fps at the end so it matches what I want does not work.

    And input is 60p so that might not work with that script.
    It might be useful to post cut out of original clip not outcome.

    Output file not much use, post some of the source

  4. That video (in the thread _Al_ linked to) is telecined film. It should be inverse telecined, not deinterlaced. In AviSynth you would TFM().TDecimate(). I believe those (or some thing like them) are available in Vapoursynth.

  5. VFM / VDecimate is vapoursynth's equivalent of TFM / TDecimate . (But there are some differences)

    He's IVTCing, but using QTGMC as post processing for combed frames
