By the way, quickly turned this from a 150 MB video to an 11 MB one with a handy bash function (with built-in help option because I can never even remember how this simplified version goes). Width is in pixels.

Example: "video-scale video.mp4 800 video_small.mp4"

function video-scale () {
case "$1" in
-h|--help)
echo "Usage: video-scale INPUT-FILE WIDTH OUTPUT-FILE"
;;
*)
ffmpeg -hide_banner -i "$1" -filter:v scale="$2":-2 -c:a copy "${3}"
;;
esac

#cli #bash #ffmpeg
