01Command

Command
$ ffmpeg -i input.mp4 -i logo.png -filter_complex "overlay=W-w-20:H-h-20" output.mp4

02What it does

The overlay filter stacks the second input (your logo) on top of the first (your video). W-w-20:H-h-20 means 20 pixels from the right and bottom edges; use 20:20 for top-left, or (W-w)/2:(H-h)/2 to center it. The video is re-encoded once, so expect a few minutes for a full-length file.

RequirementsFFmpeg is not preinstalled on Windows — install it first with: winget install --id Gyan.FFmpeg
!Warning: A PNG with a transparent background is essential — an opaque JPG will cover the video like a sticker; adjust -crf if the output is larger than expected.
