I have an mp4 video of 1080x720. I would like to crop the video to 480x270 without quality loss every 10s in video and then scale to 1080x720 (10s zoom in and then back to default repeat to the end of the video).
Does anyone know how I can crop the video every 10s without losing quality?
Thank you very much!
(P/s: sorry for my bad English)
