I recently used the detelecine command in this thread: https://ffmpeg.org/pipermail/ffmpeg-user/2025-May/059249.html
I got strange results with the `fieldmatch+decimate` combo, where decimate wasn't removing the correct frame. I also got strange results with the `pullup` filter. This may just be because my sample file was really exotic though. But yea, there's a lot of different ways to detelecine. It was confusing trying them all. But detelecine is supposedly the dumbest and simplest. I suspect detelecine has some bugs, trying a `telecine` filter on a 23.976 fps video and then applying a `detelecine` filter on a video doesn't give a correct result for me, all with default params.
