Initial size of video was 1280×720 – I wanted to make them square, and crop from top and bottom. Magical line for me was: /usr/bin/ffmpeg -strict experimental -c:v h264 -i in.MOV -c:a copy -filter:v 'crop=720:720:280:0' out.mp4 Why i’m giving this example ? Because of couple issues. One of them was seeing ugly error: Codec is experimental but experimental codecs are not enabled, see -strict -2 Second one was: Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or heightĪnd it took me a while to figure out, that FFmpeg can’t deal with audio conversion. So -c:a copy just force to copy audio stream.
