So, It's been years since this problem has existed, and after reading all the non solutions I went rogue and tried random things and I found a solution. It's a little buggy still; about a 50% success rate (but then again i've only done this a few times) Before committing to exporting any long sequences, I urge you all to make a copy of your original sequence and set a small in and out point that contains Captions - this is simply so you can see if your system is buggy and needs to be re-booted before committing to a longer export. You must have your caption files programmed as open captions within the sequence and they must be visible in the sequence or the below may not work (I haven't tried it otherwise - but am assuming that it will not work as it requires the sequence preview in order to populate the captions in Media Encoder)). Step 1- As outlined above create a test sequence (copy of your original sequence) Step 2- set all you in and out points (including with the test sequence) Step 3- Select the sequences you wish to export and go to File->Export (it will prompt you to send it to the cue since you will at least have two sequences included - one test and the one you want to export) Step 4 - Only apply your desired video/audio settings then apply the additional settings detailed below before you send to Media Encoder. (if this is your first time trying this I would do this from scratch, and NOT use a preset - the existing preset metadata f's up the caption settings and greys the options out - the goal is to have the preset field say "custom" before proceeding) Step 5 - go to the caption tab and set this to open caption. Step 7 - Select the one that says "Use Previews" Step 8 - feel free to save your preset now Step 9 - Send to Media Encoder Step 10 - Set the order of your exports so the test excerpt file is the first one in the Queue Step 11- Set the Destination Step 12- Start Queue Step 13 - watch the preview of your test file as it exports - if the open captions are present in the preview window, you should be good, and the rest of your Queue items should export with open captions If you do not see this, then I would recommend a fresh boot and a retry of all the steps above. NOTES: -Use your system while this is rendering at your own risk - my system has some kind of read/write latency issue which then freezes up my export - might be a speed issue with the storage system I am setup with, might be an issue with the program - I won't know until anyone else tries this out and experiments - let me know? -So far I can report this works for h.264 mp4s and Prores exports. Hope this helps anyone who has been plagued with this issue. Cheers.
