How to compress video size without changing much quality and without changing framerate (Ffmpeg) ?
19 septembre 2020, par WebDivaI am using this command to compress my videos :


ffmpeg -y -i video.mp4 -vcodec libx264 -crf 24 -preset ultrafast compressed.mp4




Although it works okay, there is a slight increase in duration because I am changing the framerate of videos, and we need the video to be the exact duration. Is there a way to compress videos without changing the framerate ? any help would be appreciated. Thank you.
