    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. Posting the source would be more helpful than the output. And you can preview the script before wasting time encoding it. Chances are your script on your setup already exhibits the issue

    Possibly a source filter issue - did you try LSmash instead ?

  3. First of all, thanks for answering!
    I see, no I have not tried LSmash... not familliar with it

    I'll post the source:
    https://mega.nz/file/70h3mYJR#q4O69XOhPYqWggqX93IrHFEmR6iBaL09y-gd0I7HeMI

    this is the .ts file, i converted it to .mkv but I tried encoding both.
    I mean, it looks fine, its just that it plays back really weirdly. When previewing, it plays really awfully as in uh bad fps. This happened to my successful encodes as well, even tho the output was fine the preview was slow...

  4. It's a source filter issue

    Rewrap it into a MKV first with mkvmerge (mkvtoolnix) , then use LSmash . Or if you have nvidia card and license you can use DGSource directly on the TS

    Code:
    src = core.lsmas.LWLibavSource(r'LiSA - Datte Atashi no Hero. [1440x1080i h264 SSTV+].mkv')

  5. Currently trying this out! Atleast the script didnt give me any errors when switching up the source definition, somehow i had "LSmash" installed ^^
    Will let you know if it works!

  6. make sure you're using a recent LSmash release

  7. btw is it always better to use LSmash than ffms?
    I had some other scripts and they worked just fine with ffms (de-interlacing DVD Mpeg), should i change those?

    encoding already started ill switch to the latest one if this goes wrong too. mine was 2020 march tho so its recent i guess...

  8. It works!

    Awesome, thanks for the help!

    Sometimes one works better in some situations. Sometimes a specific release or build works better. YMMV.

    DGSource is the most consistent, but does not support all formats or pixel types
