  1. I downloaded a show and liked the quality.

    The video quality was super high AND very crisp, while the file size was quite small. However, i have no idea how the show was encoded. All the video says was HEVC x265 10bit and i doubt that's enough to get the result i want.


    I tried to get some info on the file using FFPROBE but i could not get any meaningful information:



    So, having failed to get any important data (or maybe i got it and don't know what to do with it in FFMPEG), is there a way i can know all the necessary data to replicate how a show was encoded so i can encode other shows of higher size i have in the same way?

    Open the file in mediainfo and see if anything else shows up in view/text

    I got this:



    Would this be enough to replicate the encoding in ffmpeg?

    In mediainfo choose the View -> Text option

    You will be looking for a line in the video section call "Encoding settings" similar to this:

    It doesn't always exist, it depends on the encoder.
