I have an update on closed captioning in XDCAM 422 for Davinci Resolve 17.3.1
It is great to see that work has been done on moving forward with the implementation of closed captioning embedded in XDCAM 422 files. This is for many the standard delivery format for broadcast television content.
That said, my results today are that there are still problems with the implementation.
1- The best I can tell, it isn't possible to embed BOTH 608 and 708 captions in a single file. All of my clients require BOTH to be embedded so it's a guaranteed two passes just to attempt embedding both but I'm not certain if it is at all possible. Right now you can choose if you want 608 or 708 but not both. For me this means still doing the encoding of final master in Premier Pro.
2- There is also still something funky happening with the encoding of the stream. Even playing back in Switch (see attached screenshot) you can see that there are problems with the black background behind the text. Also, when viewing in other software such as Premier Pro the stream has a simple white text only stripped down look to it.
Curious to see if anyone else can describe their experience as well.
Thanks,
Erik
