Compress mp4 using FFMPEG

Raw

ffmpeg-compress-mp4

$ ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4

kfnx commented Apr 25, 2025

ffmpeg -i video.MOV -c:v h264 -c:a aac -strict -2 -pix_fmt yuv420p -q:v 0 video.mp4
I convert mov to mp4 and the result is good enough: 985 mb -> 358mb

ffmpeg -i video.mp4 -vcodec libx264 -crf 23 -preset medium -acodec aac -b:a 128k video-compressed.mp4
Next i want to compress it, got: 360 mb -> 302 mb
