• How to accelerate minterpolate in ffmpeg ? [closed]

  24 août 2020, par Ken

  I'm using minterpolate of ffmpeg(version git-2020-08-21) with this command on Windows 10 :

  


  ffmpeg -i $file -filter:v "minterpolate=mi_mode=mci:me_mode=bidir:mc_mode=aobmc:vsbmc=1:fps=60" -c:a copy "$file_60fps.mp4"


  


  But the CPU load is only about 15% to 20% while working.

  


  My CPU is AMD 4800H with 8 cores and 16 threads. And I have a NVIDIA GTX1650 with CUDA.

  


  But I cannot find any document about GPU acceleration or multithread methods of minterpolate.

  


  Have tried -threads 16 but nothing changed.

  


  So how to accelerate the process ?

  I'm new to ffmpeg. So any help would be appreciated.
