The part everyone gets wrong
-an drops audio and -c:v copy avoids re-encoding the video, so this is a container rewrite rather than a transcode. Leaving out -c:v copy silently re-encodes the whole video to strip a track you were only deleting.

More recipes, all measured
Trim a video without re-encoding Cuts a section out of a video by copying streams, which is effectively instant and lossless. Resize a video with FFmpeg Scales to a target width while computing a height that stays even, which H.264 requires. Rotate a video with FFmpeg Rotates the picture in 90-degree steps and clears the rotation metadata so players do not rotate it again. Speed up or slow down a video Changes video and audio speed together, which needs two filters because one alone desynchronises the file.
