    So I like using MediaCoder because it's one of the few GUI programs that can actually utilize NVENC for H.265 encoding.

    However, when I convert videos down from 60FPS to 30FPS (for like a Facebook video or what have you), the filesize is still that of a 60FPS file. Anyone have any clue why that might be, or if it's just a bug with MediaCoder?

    Attached is the MediaCoder preset I'm trying to use.

  2. I don't use mediacoder, but a universal equation is

    Code:
    filesize = bitrate * running time
    Notice FPS isn't in that calculation

    In the xml , you have 5000 entered, probably kb/s

    Code:
    key="overall.video.bitrate">5000</node>
    If the video bitrate was 5000kb/s for the original (video only, not counting audio or container overhead) the resulting filesize would be the same

    Well that setting isn't a target file size as far as I know, but you did make me curious about it, so I changed it to "Buffer Size" instead and that actually got me roughly the desired result.

    With an original video at 3.38GB, I did one pass at 60 with buffer size 5000 which gave me a 353MB file. Another pass at 30 gave me a 215MB file.

    No idea what the math is there, but it sorta worked.
