How to crop and scale a video with FFmpeg?
We want to crop the original video and resize it to the specified width and height. For example, suppose we’re going to scale the video to 640×360. In that case, we need to crop the original video to 640×360 and then resize it to 360×640. So the first step is to shorten the original video.
Cropping and scaling videos with FFmpeg is a fairly straightforward process. To crop a video, use the -crop top, -crop bottom, -crop left, and -copyright options to specify the crop area. Use the -resize option to scale a video and specify the desired width and height.
For example, this command crops a video to a square:
FFmpeg -i input.mp4 -croptop=0 -cropbottom=0 -cropleft=0 -cropright=0 output.mp4
