How to convert a video from 30fps to 60fps by FFmpeg ?

[kwanami]

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

I want to converter 30fps video to 60fps by FFmpeg

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

What is your source ? Is it interlaced ?

Progressive

Yes , I want real smooth 60fps out of 30fps .

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:

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

-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
