Exporting Captions | ProRes vs MXF | Timecode offset

[randyalan99]

Been having an issue exporting captions since we've had ProRes added to Preimere on Windows. I can't seem to get my captions to export as they are cut (timecode wise) within my sequence. It seems that upon export, the captions are shifted up to the beginning of the clip. Having the captions start further in the video doesn't stop this either. And if the caption sequence is set to start at the beginning with captions beginning later within that sequence, it will automatically move up captions to fill that blank space. Blank captions seem to get overridden by ones that have text. My other solution is that MXF exports with embedded text seem to hold the caption timecode correctly, it's ProRes that does not translate right.

Here is how the ProRes files comes back into Premiere after exporting.

I don't really understand your screenshot. But I get the same general results you describe:

I am on Win10. I compared two sequences, both with 608 Closed Captions and exported to .mov Prores LT and to mxf op1 with embedded captions. One sequence had 3 captions starting at zero; the other had caption 1 at about 2 seconds and 2 more captions with gaps between all.

Upon reimport, the mxf kept their positions; the .mov "gap" sequence moved to the beginning, but appeared to keep the gaps between later captions.

Note that both mov and mxf started zero at about a half second from the beginning.

Sorry I should have explained the screenshot a little more. You are correct though with your description. In my screenshot the clip on the right is the MXF file imported into the timeline.

I am also in Win10. Perhaps this has something to do with the ProRes integration since it is fairly new to Windows Premiere users.
