Hi, I've been cropping a number of mp4 videos with ffmpeg but I was just wondering whether there is a way of doing it that doesn't involve re-encoding.
no, this is not technically possible for obvious reasons: you need to decode the frame, crop and re-encode the completely new image. due to the very nature of video encoding, you cannot remove portions of an image without re-encoding the rest as pixels in an image are strongly related.
