Hi Rich,
The black QT method will work with the Io LA.First, try connecting a consumer TV directly to the Io LA via composite instead of through the Beta deck to simplify things (you might have line blanking enabled on the deck). Make sure CC1 is enabled on the TV.
Also make sure your FCP sequence and output settings are set to 720×486 (not 720×480).
If you still aren’t seeing the captions, have the CC service company do a calibration test for your system to make sure their settings are right, and then they can send you a new black QT CC file with the correct settings.
Hope this helps,

[Daniel Bernardoni] “They have been talking to CPC and they said that the combination of software of Final Cut 7.0 and blakcmagic is not able to use .scc file that will match with my drop frame show.”
As far as I know, we haven’t experienced any problems using .scc files on Blackmagic cards in FCP7. So I’m not sure if your captioner is accurately relaying information they got from CPC.
When you generated the proxy movie for the caption company to use as a reference, did you change the frame rate or make any other edits? The proxy needs to EXACTLY match the entirety of the finished FCP sequence. The kind of drift problem you’re experiencing can occur if you generated a 23.976fps or 30.0fps proxy movie for a 29.97 drop frame sequence, so the captioner’s reference would be off.
I can think of some other problems that could occur but it is definitely fixable.

I’ll be there at CPC’s booth SL5620. Hope to run into many of you guys as well. 🙂

Hi everyone,
I’d like to clear up a few misconceptions in this thread.First off, Shane and Chris, Final Cut Pro 7 most definitely CAN print to DV tape via Firewire with closed captions. We even have a video tutorial for it here: Print to DV tape with closed captions in FCP7. All that is needed is the proper sequence settings, and a properly formatted caption file such as one generated by MacCaption. I suspect the OP’s problem is due to a problem with the sequence settings or the captions file.
David, the HVX200 can record DV with closed captions via Firewire as it doesn’t touch the DV data stream. However, it will not convert the DV VAUX closed captions into line 21 captions on the analog outputs; it only works in and out via Firewire. You can pop the HVX200-recorded DV tape into another deck and then the captions will come out on line 21.
MacCaption can also add the closed captions directly to an MPEG-2 file. Compressor only exports CEA-608 data into MPEG-2 (contrary to the FCP manuals, Compressor does not output CEA-708 at all, we’ve tested it) which is the old analog captioning standard. Another idiosyncrasy of Compressor is that is requires a SCC file formatted slightly different than the one used for FCP print to DV tape. Fortunately MacCaption has the necessary features to deal with all of these issues.

Hi Daniel,
We have also found this to be the case.Fortunately, the new drivers support the Final Cut Pro 7 closed captioning feature, which in some ways is more convenient because you don’t have to render the video anymore.
To make use of the new FCP7 workflow for standard definition output, you need to use a QuickTime 608 Closed Captions track, or a .SCC file. Almost any closed captioning company which uses CPC’s MacCaption software will be able to generate these files for you. (HD closed captioning is now supported as well!)
Hope this helps,

Sorry I didn’t spend too much time with it, and most of the time was just trying to get the subtitles to work at all.

I haven’t tested if there is a time limit to the subtitles, but in my experience with Encore CS4, the Blu-ray subtitle encoding has some issues which are not apparent in the simulator. For example, any time the player jumps to a different time in the video track (i.e. user hits next/prev chapter or ffwd/rew), the subtitles disappear for about 15-30 seconds, then start working again. This happened on multiple Blu-ray players including the PS3.

[Moises Chavez Jr] “Ok this is the process……….. Tape/FInal Cut/Transcode/upload to broadcast for Air”
Transcode to what exactly? That is the key.
If the destination format is SD 720×486 29.97fps with line 21 captions (ProRes, uncompressed) then you’ll be fine with the line 21 captions captured from tape. If it is transcoded to anything else (DV, DVD, MPEG-2, H.264, HD, web video, etc.), you’ll need software to convert the captions into the format used by the destination.
Hope this helps,

Hello Moises,
The “Show Closed Captioning” dialog box in QuickTime Player only works with QuickTime caption tracks (QT 608 or QT DTV 608/708 tracks). What you have is the line 21 data recorded as part of the image, which is a different way of recording closed caption data.If you just want to print the file back to a SD tape or a monitor, then you should be fine with what you have. But if you want to convert the line 21 captions for use in a different format (for the web, DVD, or for HD video tape, etc.) then you would need closed captioning software or a service company to convert the data to the appropriate format.
What do you want to do with the closed captions from this tape?
Hope this helps,

Hi Joe,
FCP can capture HD video with closed captions, but it will store the captions in Apple\’s QuickTime 708 track format which is not read by Avid systems. Conversely, Avid can capture captions in a DNxHD file, but those captions won\’t be read by FCP. In both cases, converting or editing the file will wipe out the captions.To my knowledge there are no 3rd party tools yet which can manipulate the captions in a Avid DNxHD file. I hope this will change in the future.
Hope this helps,
