Closed Captioning from FCP

[Steve Cohen]

We do this on a weekly basis, but we use MacCaption to create our own caption files and we us the BlackMagic MultiBridge extreme.

Once the caption file is created we do the following.

Place it on the top line of video in FCP.

So you got the “Show” on V1 and the Caption file on V2.

Click on the Motion tab of the “Viewer” and set the bottom crop to 99.
Make sure that “Center” is at 0 and 0 not 0 and -1.

When we used to use DV quality clips in a 8bt uncompressed timeline I would see this happen a lot.

Then go to Sequence>Settings (Apple 0) and Make sure the “Frame Size” is at 720 x 486 CCIR 601 NTSC (40:27) and NOT NTSC DV (3.2).
The “Compressor Setting” should be Uncompressed 8-bit NOT DV/DVC PRO.

Now render and “Edit to Tape”.

The other problem that we have run into is that in the BlackMagic preferences there is a setting under processing that Capture VANC input line needs to be set to 21 instead of 18,19 or 20 that it defaults at.

I don’t know much about the Kona, but maybe there is something here that will help.

Good Luck.

yeah I can’t get it to work if I crop at all which makes no sense.

it sounds like a fcp 6.03 bug to me though if it works for you in 6.01 (I just upgraded from that for XDCAM EX work) I know its not the kona-lhe since I see the problem on the canvas as well as my
broadcast monitor.

[Steve Cohen]

It could be 6.0.3. I never used that version. I upgraded to it and had other issues with Live Type and the BlackMagic were the texture backgrounds would disappear so I went back to 6.0.2 and then went to 6.0.4. I’m currently at 6.0.5 and have not problems, why don’t you update to that?

This is exactly what we’ve done. But for whatever reason the caption will not display on our screens. We cannot seem to figure out what is preventing it from displaying. We know the data is passing through on line 21 because we can see it on the monitor, but the caption does not show. ????

did you download the test files and do the procedure?
what were those results?

Yes. I used the test file and got the same results. I used AJA TV to bypass FCP and still no results. Very confused.

If you saw no report of text coming up on the screen denoting the line and row on the black cc file you do have an issue.
Is your sequence set to 720 x 486?

Alan you are monitoring this through composite video
on a TV with CC turned on right? (thats how I test/verify mine)

most pro crt monitors don’t have cc capability.

and as for my cropping problem in 6.03, I found a work around.
my cc file provider gives the option of an animation codec
quictime with an alpha channel on the cc data.

just drop it in the timeline on video 2 and render…..all done!

Hi Alan,
Your timeline MUST be 720x486, 29.97fps, Upper field first. No other setting will work for adding line 21 closed captioning. The line 21 data must go into those extra 6 lines, otherwise it will not end up in the right place for the CC decoders to recognize it.

If you have run the CPC black movie calibration video ( https://cpcweb.com/blackmovie/ ), you should have gotten the row & column settings which are compatible for your particular hardware. If the black movie was made using different row & column settings, it will have to be re-exported by the captioner with the correct settings.

You can put 720×480 video onto a 720×486 timeline, but the timeline itself MUST be 720x486.

I have a project coming up that requires CC of an HD video. This is my first time CC’ing, and from what I’ve read this much different than CC for SD.

Could someone simply shed some light? As of June 17, 2009 one cannot output CC’ed HD content through a Kona 3, correct? This would require a Matrox MX02?

Browsing around on the forums, I see mention of a Kona update, but apparently that only fixed an issue with CC for HD, correct?
