– For free!

Make sure you have ffmpeg on your system (ffmpegmac.net is your pro tip) and located in your $PATH such as /usr/local/bin

Add the following to a file named .bash_profile in your home directory.

function proresify() { for f in "$@" do ffmpeg -i $f -vcodec prores -profile:v 2 -acodec pcm_s16le -filter_complex asetnsamples=n=16384:p=0 $f.mov done }

Usage: Fire up a terminal and browse to the folder containing your video files that Final Cut Pro won’t process. Then type, for instance, proresify *mp4

Voilá!
