that's for SD. HD is different.

It's off by a few seconds (I'm pretty sure.)

And it's not clear if only the chunk ON THE TIMELINE you replace is missing the CC info, or you just dropped a fix back onto a Master, and THAT was missing the CC data. If the former, it's a process issue, if the latter, you may not have data to begin with--- hence below.

You're talking about the data track method, and the hardware and resolution requirements are very specific for capture, and Data track must be enabled prior to beginning capture? And there is also data mixdown in the "mix" as well.

It's supposed to work if you take a master in and just spit it back out which isn't all that useful. I have not experimented with the data track and would appreciate any clarification on how to maintain CC in HD while changing the video.
