ffmpeg basics for video creators
Short answer
ffmpeg is a free command-line tool for working with video and audio. Beginners mostly need five jobs: trim a clip, convert format, resize, extract audio and burn in subtitles. You can ask Claude Code to write and run these commands, then check the result. SkilledCut's skills require ffmpeg to be installed.
