FCP 7 Digital Delivery with Closed Captioning in HD

[Kevin Hamm]

I’ve read that note, and it seems to be the output is not my particular issue, especially since my monitor doesn’t support CC anyway (another issue entirely). My problem is that it appears that the CC isn’t being written to the tape, although it might be as metadata 608 instead of Line 21, but that would be weird in the extreme.

Today I’m going to test and see if files containing the 608 CC info are useful for our broadcast. If they are, great. If not, I’m back to square one.

Hi Kevin,
DV does not store its caption data in line 21. Weird as it may be, DV in fact does store the captions as metadata in the DV stream. This is because DV is a 720×480 format, but line 21 does not go in the 480 lines of active picture data. (The same is true for DVD which is also 720×480.)

Most DV decks will convert the metadata into line 21 when you go out via the analog outputs (although in the case of the DSR-45, only via the Monitor output).

If you want to verify that your DV tape has captions, you can either hook up a regular consumer TV to the monitor output of your DSR-45, or after printing to DV tape, capture it back in by firewire and then decode the DV captions using the MacCaption demo.

Hope this helps.

huh. I keep thinking that the more I find out the less I know. I will try this, and post my results.

[Bouke Vahl] “For the archives, the timecode in the .SCC file is relative to the running length, not the timeline TC.
Thus, if your timeline starts at 01:00:00:00, and your first caption is after two seconds, that should be 00:00:02:00 in the .SCC file. “

Bouke,

Thanks much! This was killing me until I found your post.

Seems to have solved one problem for me.

I can’t seem to get 10bit SD outputs to work quite right (Kona 3) and I’m getting bad characters at the end of each string – but I’m closer than I was yesterday.

Thanks again.

Actually, zero-based .scc files are only for FCP outputs via Edit To Tape or Print To Video.

If you try to use Compressor to integrate the close captioning, the .scc files need to match the TC of the QT movie.

Took me hours to figure that one out… Apple really tripped this one up!

This has nothing to do with CPC but it does involve closed captioning. Working on a project where the spot has already been closed captioned (tape to tape) and was digitized using FCP 7 with an AJA LHi card. I have verified that the captured spots have captioning in QuickTime but after tagging them and attempting to lay off to tape the captioning disappears. Any thoughts? I feel like I have had this problem before……..
