Remarks
$ Only CEA-608 closed captioning data in your sequence can be embedded
in your exported Matrox .mp4 file.
$ Embedding of closed captioning is supported only when exporting a
sequence that has a frame rate of 29.97 fps to an export format that also
has a frame rate of 29.97 fps.
$ The closed captioning in your Matrox .mp4 file can be displayed when
you play back the file using supported applications and mobile devices
that are capable of playing back .mp4 files with closed captioning. If you
don’t see the closed captioning when you play back your Matrox .mp4
file, try changing the file’s extension to .m4v.

to export, such as
