A note about the North American .scc problems. was created by Andreas Kiel
By FCC laws in North America broadcasters are forced to deliver a certain percentage of the program with CC subtitles. Broadcasters often enough move that burden to producers/production companies. This means for the producer to create an MXF with the subtitles muxed into the stream.
The options to create these files on a Mac are very limited. There is Telestream MacCaption (1100 - 6000 bucks) and Adobe Premiere Pro. Using a service is another option.
Adobe claims PPro works seamless with that - but it doesn't seam to be that simple – if one looks at the forums.
Both apps use their own MXF and SCC libraries independent from the Apple components.
The biggest problem though is that there is no way to prove those files outside the above apps.

QT Player (QT Player 7.x) can display .SCC files - but only if they are in their own track.
You can add a .SCC file to all QT files using Compressor, but you can't mux them into a MXF stream. Some stations accept H.264 stream with a valid SCC track attached, this should work with Compressor.
There are free tools to convert SRT to SCC – but these don't care about some SCC limitations.
I put a little research time into that issue. Since a simple person like me can't expect any response from Apple I spoke to HPM (Hamburg Pro Media) the original developers of the current QT MXF components (I worked with the company for some years). They told me that the QT MXF components were never thought to support other tracks than video and audio. The current Apple QT components didn't change compared to the original ones (except not searching for a license) in my opinion.
So a quick check/preview seems not to be possible.
Final Question: Who on this list is affected by this problem(s) ?

P.S. Asking for a favor. If somebody is using PPro pro here, would it be possible to send me a DFXP sidecar file exported from a subtitle track??
