In the past we sent a file out of house to a Facility that used Mac Caption. The facility had delivered to the network we were working for before but they somehow found a way to mess the file up and it created an audio issue at the network during encoding.
I've never run Mac Caption but my understanding was that it could either add the captioning to the existing file or create a new file that added the CC from the CC data file, I don't know what format that was but it was done out of house.
For whatever reason when they tried to add the captioning to our file it didn't work but when they made a new file it did. I was surprised that they hadn't figured this out in previous deliveries to the network but they said they had no way to properly QC the CC'd file to duplicate the process the network was using. It seemed like they were just doing trial and error but I didn't appreciate my audio/.mov being blamed for the issue when it was the CC insertion that caused the problem.
Later I experimented with just extracting the captioning track using QT 7 and then pasting that into a prores file I had made. It all seemed to work within QT 7. We had made a video change that didn't effect the captioning so I figured I should be able to just insert like I did. Unfortunately the facility wouldn't guarantee that the file would work so they refused to just upload it to the network so I never knew if what I had done would work. The facility wanted to make more by re inserting the CC file and charging for it rather than just upload my file. I understood they didn't have a means to guarantee the file I made but I felt they should have known if it would work or not given they were also our QC house.
I'd be curious if Adobe Media Encoder has anything that would add CC. I have never looked but it doesn't sound promising.

I tend to avoid the much-dreaded gamma-shift that way — although for me it's never been 100% fool-proof.Be aware, however, that it seems that often to get the SAS to function correctly you sometimes need to duplicate the sequence, lay in the mixdown, and delete all the underlying video clips (if you haven't already). Sometimes MC gets a bit finicky about its same-as-source'ness. And this is even if you only have the mixdown track selected AND if it's sitting on top of everything else.Not sure if this answers your question…D

We used to go to tape and then capture the file in FCP7. Clients don't want the tape anymore, and newer capture cards don't work with FCP7.
