I have an HD video (1920x1080). I am trying to crop the video from the center so the resolution is (960x1080) and looks like a portrait video. I have tried the following command with no luck:
ffmpeg -i in.mp4 -filter:v "crop=960:1080:480:0" -c:a copy out.mp4
This just outputs a video at the same size: 1920x1080
Any suggestions would be appreciated.
