  1. Anyone know how to convert a video from 30fps to 60fps by FFmpeg with bwdif filter ?
    I have used Hybrid or Twixtor but the result didn't meet my expectations
    THANKS
    SOLVED

  4. Do you want real smooth 60fps out of 30fps? Missing frames must be interpolated.

  5. What is your source ? Is it interlaced ?

  7. For the conversion of a movie from 30 fps to 60 fps with ffmpeg you can include the code -r 60 or -framerate 60

    for example:
    Code:
    ffmpeg -i input30fps.mp4 -c:v libx264 -preset veryslow -crf 24  -framerate 60  -profile:v high -level 4.1 -tune film  -acodec copy   output60fps.mkv
    just after the conversion mediainfo should give you this output

    Frame rate: 60,000 FPS, the -r 60 parameter is also accepted by x265

  8. -r 60 will just duplicate frames from a 30 fps source , motion smoothness will be the same as 30

    You would need to synthesize new in-between frames using minterpolate
    https://ffmpeg.org/ffmpeg-filters.html#minterpolate

    But if you already tried twixtor, and didn't like the results, you won't like the minterpolate results either. It will fail and produce artifacts under the same conditions as all types of motion interpolation. You can try avisynth too, using mvtools2, svpflow etc.. but they all fail and produce edge morphing artifacts to some degree
