    Quicktime h.264 export doesn't match sequence

    I got an aaf of an Avid seq from another editor, along with a Quicktime export of the same. Quicktime was h.264 directly from timeline.  Avid was MC 8.5.x Mac.

    The project was 1080p23.976, sequence was 23.976 fps and all media was DNxHD36 in his Avid. Some shots were stock, at 29.97fps but imported into Avid. These shots show the 'frame rate' icon on them.

    The Quicktime export of this seq does not match the AAF in duration. There are extra frames after the 29.97fps shot. It's almost as if the export process 'interpreted' the 23.976 as 29.97.

    If exported as 'same as source' this issue doesn't happen. Only if directly exported as h.264. Unfortunately I cannot duplicate the issue as that Avid isn't near me.

    Anyone observe something like this?

    Any chance you had the frame re-order option on when exporting H264? You could try without that but otherwise I am not sure. I always export a same as source and then convert it in compressor to h264 and haven't had the issue you are seeing.
