The part everyone gets wrong
Capitals are the base video and lowercase is the overlay, so W-w-20 means twenty pixels in from the right edge. A two-input overlay needs -filter_complex with explicit labels; -vf cannot express it and fails with an unhelpful argument error.

Trim a video without re-encoding Cuts a section out of a video by copying streams, which is effectively instant and lossless. Remove audio from a video Strips the audio track and copies the video untouched, so there is no quality loss and almost no work. 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.
