Resizing videos in OS X / macOS #

For years, I used Stomp for resizing videos under OS X. However, in addition to recently being retired, it has had trouble processing a number of formats of late, either hanging altogether or displaying lengthy time estimates (e.g., ~6 hours to scale a 6 minute video by half).

Happily, ffmpeg makes quick work of scaling video while preserving the aspect ratio, e.g.,

$ ffmpeg -i in.mp4 -vf scale=640:-2 out.mp4
