Error Exporting Chapter Markers from FCP X

After upgrading to Final Cut Pro X 10.0.8, I am having problems exporting chapter markers. Specially, at the end of the export, this error message appears and cancels the entire export:

Error Message: "The operation could not be completed because the chapter marker track could not be written (error -12769)."

As you can see, none of my markers are closer together than one to two minutes, and the error message appears whether I have a marker at the very beginning of the project, or occurring a few frames in.

The only report of this problem on Apple's support forums was caused by trying to read FCP X 10.0.5 markers in 10.0.6. In this case, all my markers were created in 10.0.8.

This error persists even after trashing FCP X preferences and moving marker positions.

The file will export perfectly when chapter markers are not included in the export.

At this point, I don't have a good workaround.

Thanks,

Larry

MacPro, Mac OS X (10.5.8)

I haven't encountered this – in practice or in reports from others.

Try removing the markers (you can always do a bunch of undos to put them back), creating a new project and pasting the old sequence into it. Drop a chapter marker after 30 seconds and see if you can export a short section that includes the marker. Choose HD for output device to avoid wasting media. If it exports, I would think you would be good to go for all the markers.

Russ:

OK. I've spent the last three hours testing. Here's the short answer.

Apparently this message indicates a corrupt marker. The way to fix it is to delete markers, individually, starting with the end of the project.

When deleting a marker, write down the timecode location and title of the marker, because, ultimately, you'll be creating a new one at that location.

Keep deleting markers until the Project will export properly with chapter markers. In my case, deleting five markers did the trick.

Then, create NEW markers, don't use Undo, at the old locations. The new markers will not be corrupted and the project will export properly.

Yes, this is a bit time-consuming, but it has the benefit of working.

Larry,

Glad it worked. And thanks for sharing the info on corrupt markers. (I'm guessing that copying to a new project w/o markers and adding back new ones would have worked. Fortunately, I don't have any way of testing that.😉)

Hi I have this same problem right now!

Mac Mini
OS 10.8.5

FCP 10.0.9

No recent upgrades, nothing has changed.
It had been working fine since I bought the Mac Mini + software in 2013…)

I have already tried removing the markers, deleting all markers and making new ones, creating a new project and pasting the old sequence into it (without markers), creating new markers in the new project, etc...

I still cannot create a master file (unless I deselect 'use chapter markers'), or unless I select a range of the project which does not include markers!
Please Help!
