I queued 3 videos from PR to AME with the "import sequences natively" checked. Processed and they uploaded to Vimeo correctly.
I could see the burned in captions as AME transcoded them, and the captions are in all 3 on Vimeo.
Not sure what is happening.
I selected one sequence at a time from the timeline (Ctrl-M) and sent to the queue from the export dialogue.
Then I changed the sequence names (so Vimeo wouldn't choke) and selected the 3 in the project panel, File -> Export -> Media, and set to burn in, specified the Open Caption stream, and publish to Vimeo. And queued. I checked one of them and the settings were correct. I could see the captions during the processing. Still worked correctly.
I've also tested again.
1. I chose 3 sequences and cmd+M'ed for plain export. Set format as h.264 Vimeo 480 SD. Queued to AME, and exported fine.
2. I chose 3 sequences (same ones) and cmd+M'ed. Checked publish to Vimeo, format was the same. Queued to AME and when exporting I could see that the open captions were missing.
3. I chose 3 sequences (same ones again) and cmd+M'ed, checked, publish to Vimeo, then set Captions Export Options as Burn Captions into Videos and Stream Format as Open Captions.
On #1 and #2, I didn't touch this option.
NOW I can see the open captions as AME is rendering.
BUt what I don't understand is why I have to check Captions Export Options when I'm publishing the videos to Vimeo. Shouldn't I had to do the same for #1 method?
Anyway, I know how to fix them now.
I still think it's a bug.
