name of the typedef, as for all the other structs declared in this
    
header.

  • Is it possible to make 2 different quality videos match each other on a frame by frame basis

    26 décembre 2022, par Jon Freynik

    I have 1 high quality version and 1 low quality version of the same video. Is it possible to encode / degrade the high quality version to match the low quality version on a near perfect, frame by frame basis ? or do I need to know exactly what steps /software was used to compress / encode the low quality version ?

    &#xA;

    When I try to match codecs and quality the frames almost match but are a little off.
