FFmpeg: Reverse a Video (Audio + Video)

reverse filters the entire video backward — note that it loads everything into memory, so works best on short clips.

Command

ffmpeg -i input.mp4 -vf reverse -af areverse -c:v libx264 -crf 23 -y output_reversed.mp4

-i	Input file. Can be a video, audio, or image. Repeat for multiple inputs.
-vf	Video filter chain. e.g. scale=1280:720, crop=, fps=30.
-af	Audio filter chain. e.g. silenceremove, loudnorm.
-c:v	Video codec for output. e.g. libx264, libx265, libvpx-vp9.
-crf	Constant Rate Factor — quality target (lower = better, larger file). 23 is visually lossless for libx264.
reverse	Video filter that buffers the entire stream and emits it in reverse.
areverse	Audio counterpart of reverse. Often paired together.

Both filters require the entire stream in memory — keep clips under 1 minute or use a workstation with lots of RAM.
For boomerang-style loops, use the loop recipe and append a reversed copy.
