I tried to extract the CEA-708 cc from a MXF file, but I had no success.

I need to extract a raw data and put it into a file again.

How can I do that?

Hi,
I'm using a mac and I'm unable to extract captions from an MXF file. @cfsmp3, would you be able to look into this issue again?

We'd need a sample file to test.
