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.

Your command is doing fine, and ffprobe will show the resolution as 960x1080

  Metadata:

My suggestion is to go through some of the examples from https://ffmpeg.org/ffmpeg-filters.html#crop to see if you have any expected result.

Try this:

ffmpeg -i in.mp4 -vf "crop=960:1080" out.mp4
