ffmpeg -i video.mp4 -c:v libx264 -crf 23 -preset:v fast -g 30 -vf scale=your_res:720 -y scaled_video.mp4

ffmpeg -i video.mp4 -acodec copy -c:v:0 libx264 -b:v:0 4500k -y scaled_video.mp4

ffmpeg -i video.mp4 -vcodec libx264 -b:v 4500k -y scaled_video.mp4

@lomero and 1080p/720p to 360p command?

i use this for 1080p to 720p

ffmpeg -i source.mp4 -vf scale=-1:720 -c:v libx264 -b:v 4500k -c:a copy output2.mp4

works fine

and 1080p/720p to 360p command?

about my code above: yes, 3. similar but different

about your resize 360 simply use:

ffmpeg -i source.mp4 -vf scale=-1:360 -c:v libx264 -b:v 4500k -c:a copy output2.mp4
