  • Various profiles and settings in H264 AVC codec

    19 avril 2022, par Tina J

    When I convert a video with ffmpeg, and use mediaInfo to review the metadata, I see the followings for the video codec :

    


    Format : AVC 
Format/Info : Advanced Video Codec 
Format profile : Baseline@L3.1 
Format settings : 1 Ref Frames 


    


    Whereas for some other videos, mediaInfo shows this :

    


    Format : AVC 
Format/Info : Advanced Video Codec 
Format profile : High@L4.2 
Format settings : CABAC / 4 Ref Frames 


    


    What are the differences between these two profiles and settings ? Do they have any effects on the compression ratio/file sizes ? Any pros/cons ? My goal is to reduce the video file sizes at much as possible with negligible quality degradation.
