  • Targeting a specific file size in vp8+vorbis encoding using ffmpeg

    4 août 2021, par Mohammad Zamanian

    I have a couple videos that I want to encode to vp8 for video and Vorbis for audio. This is the FFmpeg command I'm currently using :

    


    ffmpeg -y -i input.mp4 -map 0:v:0 -s 640x360 -filter:v fps=20 -c:v libvpx -crf 10 -b:v 200k -map 0:a:0 -b:a 48k -c:a libvorbis output.webm


    


    I want to have control over output file size and limit it to 3MB without clipping the video, but instead, lose quality. so I cant use -fs 3MB.

    


    How can I determine the file size based on video and audio bitrates and duration ?

    


    How can I limit the file size without clipping ?
