If you feel like this example could be improved, you may edit this example here.

Convert a 60fps video to 30fps (or any frame rate) - handy for smaller files, matching an editor’s timeline, or taming high-frame-rate phone footage.

fps=30 - sets the output frame rate; swap in any target rate. Frames are dropped or duplicated as needed.

-c:a copy - copies the audio stream untouched, so only the video is re-encoded.

Tested with FFmpeg 8.1.
