On my macOS laptop I change video dimensions easily using ffmpeg, normally something like
ffmpeg -i vid.mp4 -vf “scale=iw/2:ih/2” our.mp4
On the iPhone I can’t find out how I can resize a video that I recorded.
How do I do that (for free)?
I want to make saved videos smaller (they have already been recorded, I know I can change the recording dimensions in settings)
