i have the follow issue: i would stretch a video from 11min to 22min. The Input video have a frame rate of 30FPS
i stretch ( slowmo) ist with: ffmpeg -i 1min.mkv -r 60 -filter:v setpts=2.0*PTS output.mkv (tested with 120 or 240FPS too)
after that the Video stutter and i need to smooth it.
I use the following command:
ffmpeg -i output.mkv -filter minterpolate=mi_mode=mci:mc_mode=aobmc:vsbmc=1:fps=30 output_minterpolate.mkv
The Result is great but there are some stuttering parts, or i say some parts with stroboscok effect. I have uplaod a testfile and you can see the effect at second 9 at the tree on the right side and at second 18: the sign on the left side.
in the complete Video i see sometimes this "strobo"-Effect on different things.
Is there a way to improve this / eliminate this effect ?
Here is the Test-Video: https://youtu.be/kxaIQS0YTQA
