Converting from imovie on Windows

I’ve recently migrated off a Mac onto Windows.

After the event I found all my home video files were encoded with the Apple Intermediate Codec and couldn’t be played or edited on my PC

After lots of trial and error I found ffmpeg could convert.

A created a simple batch job which I ran from a command prompt to convert all the videos. It took over 2 days to complete but appears to work fine.

the batch job was a simple one line:

FOR  /R %%a in (“*.mov”) do ffmpeg -i “%%a” -c:v libx264 -preset slow -crf 20 “%%~dpna.mp4”
