How to change frame rate of video on Mac

QuickTime player and iMovie doesn’t support to export with an option of changing frame rate.

It’s frustrating, and downloading from an unidentified application from web is also not the best.

Use FFmpeg

ffmpeg -i [original file] -filter:v fps=30 [output path]

If you don’t have ffmpeg on your machine, check it
