Quickly convert movies using FFmpeg
An interesting problem someone had recently on Audio Video Productions on Stack Exchange. He/she needed a quick way to convert videos using a command line program, i.e. FFmpeg.
If you don’t want to mess with the (endless) command line options FFmpeg provideos, the solution is pretty simple. Just use one of the provided presets and FFmpeg will figure out the rest for you.
ffmpeg -i highres.avi -vpre medium lowerresforceh264vpremedium.avi
