  • The Quicktime frame rate bug still a thing it seems

    I wrote about it before but this is still around:
    – I have a sequence I need to add black to.
    – If I use Premiere’s own generators, a still image or leave the track blank, Quicktime player will see some really weird frame rate on the exported Prores file. I exported as 23,976 and QT said it was 21,16.
    – This won’t happen If I render some black out of AE as a video file and use that.

    The files seem to be OK if I bring them back to Premiere, but I’ve gotten files back from broadcast clients who use a system that probably sees what QT would see in the file.

    I just exported a prores file on a mac using premiere black for
    the very end for a few seconds.

    the sequence and exported file are both reading as 29.97

    on a similar note, if I didn’t use premiere black and just
    extend the work area to be black, then export or queue with media encoder
    it refuses to have the extra black on the end now, which it never
    did before.

    now I have to add black if I want it included at the end of an exported file….weird.

    Interesting. Out of curiosity, have you tried the same things with other CODECs?

    I can repeat that error all day long with Prores. MXF files and H264 work fine, although I can only check the H264 files in QT.

    You may want to check the H264 files in VLC…and, for the record, are you exporting H264 files with QT wrappers or as mp4?

    The problem is with Quicktime somehow seeing a crazy framerate. H264 mp4s render correctly and show the correct frame rate in QT player.
