I'm trying to resize (keeping quality) and reduce frame rate to 30, I've seen various command but I'm having difficulty.

This seems to resize nicely

ffmpeg -i final-video.mp4 -aspect 886:1920 -c copy final-resized.mp4

I've also see -r 30 and -filter:v fps=fps=30

But neither seem to work in-conjunction with the resize command.

You can change resolution without reencoding. And if youre reencoding, you should set a bitrate or crf value. – szatmary Dec 02 '19 at 02:38
So can i change the resolution and bitrate without encoding, if so how? – Jules Dec 02 '19 at 06:30
No, you can’t. Changing the resolution and bitrate REQUIRES reencoding. – szatmary Dec 02 '19 at 06:31
So whats the complete command line for that? – Jules Dec 02 '19 at 07:13
Although I can resize I cannot reduce the bitrate to 30. – Jules Dec 02 '19 at 21:33
