FCP can only create and embed the older CEA 608 standard. Here is a good short article to explain the difference to CEA 708: www.3playmedia.com/blog/difference-cea-608-cea-708-captions/
You could check if your client allows you t use CEA 608 as It is still compatible. If yes all can be done within FCP. I've not had the case were a client specifically asked for a CEA 708 so not sure which software to use to either convert a CEA 608 created in FCP or to create a new CEA 708 from scratch..
We never mess around with captioning. We upload our master deliverables directly to VICAPS. www.vicaps.com/. They send back a master with embedded captioning that is perfect every time. They also provide the SRT files. They are inexpensive, reliable and very fast turnaround.

To get a CEA 708 you need Telestream MacCaption and that's not really cheap, or as said PPro but that one is still buggy.
As the others said, ask whether they really need CEA 708 or if CEA 608 will be okay as well.
Additionally ask whether they will accept Apple ProRes - most stations will do.
If they insist on MXF ask whether they accept a sidecar file with the captions in 608.
If they don't, use a service to create an embedded file. Probably it's easier and cheaper rather than buy/rent the above mentioned apps.
Inside FCP you can convert SRT or ITT to SCC (CEA 608) in case you have no .scc file. FCP does a pretty good job showing caption errors and making suggestions how to fix.
While the CEA 608 specs say 32 characters per line this is only true if there are no colors, style or special characters. So some stations say they accept only 27 characters per line. Ask for this as well.
If positioning is important for you check the FCP manual about this.
Some time ago I made a generator for this. It's a visual helper for this: www.spherico.com/filmtools/TitleExchange...A_Grid_Installer.dmg

How much are you paying for that per minute?
And what if I need formats other than SRT?
We have an account with them and usually receive a custom quote for captioning. I checked a few of our last orders and typically we paid $100 for a .30s commercial with embedded FCC compliant captioning and we paid $50 for each 3 minute video with standard captioning SRT files. For embedded broadcast that is roughly $200 per minute. They seem willing to work within a provided budget. Transcriptions have always been accurate for us. On longer form video that is narrated we usually send along the script copy, but I don't know if they actually use it. We have never had an issue with accuracy on any project and they guarantee that anyway.
I believe they have many formats but we have always used the same standard style for embedded broadcast and sidecar SRT's.
For us it's more about convenience, speed and not having to bother with doing it ourselves. It's also a service we mark up in the total project cost so we're not out anything by doing it. We usually get the turnaround within a day or two. Check them out and see what you think.
Well the way I look at it is that most of our broadcast work is .15s and .30s spots so paying $50 or $100 for those seems reasonable for embedded captions. SRT files for online work seems really cost effective. The process and relationship with the vendor has been great and that means a lot too. I’ll look into Rev and see if that’s a solution for us as well.
