I have not seen any consumer software that includes the ability to add EIA 608 or EIA 708 ATSC broadcast closed captions to video files.

Adding support for embedding CEA/EIA-608 closed captions in the video GOP user data has been on the to-do list for ffmpeg for a long time but I have not heard that there has been any progress in that area.

Some consumer software exists for creating source files that broadcasters can use to add ATSC captions, MovieCaptioner.

[Edit]If you have a few thousand dollars to spend on professional closed captioning software, look at PixelTools
