Does ProRes preserve closed captioning from TAPES?

LOL! Well actually… he’s one of the closest things to it :). That’s fine you want a second opinion. But it’s not cool to pretend like he didn’t answer you. A less obnoxious response would be directed at Gary saying “Are you sure? I’ve heard different information? Can anyone else confirm this, etc.” Instead, to me it looked like you didn’t like the answer he gave, so you chose to ignore him.

[Jim Calahan] “ProRes does capture line 21 data in SD as it’s 720 by 486 “

IN FCP?
If so I stand corrected on the SD CC capture.

I was always able to do it correctly in other capture utilities (VTR xchange, Virtual VTR, and in a number of wintel apps), but in all of my HD testing the CC data is no longer there (in correct placement) when the content is captured thru the Final Cut interface.

–according to a mutual friend of yours and mine in grass valley, one of the biggest issues with ProRes/ FCP 6 is the striping off of all ancillary metadata.

“if you insert anything into it it will destroy that data like Andy says.”

Correct- hence the reason I asked for a better explanation of the purpose of wanting to capture that content ….

My apologies for being short with you Gary.
I am doing a cut and trim of a television program. Im actually preserving the entirety of the program, just removing commercials. Everything is coming in on HDCam 1080i tapes. Im using an out of house tape-digitizing facility, and it donged on me, “wait, I wonder if these programs have CC?” Although they were not labeled with CC on slate or on the tapebox, and the digitized data files were already delivered to me, and I couldn’t find traces of CCs. Regardless, I can find out which programs do and don’t have CC with the producer. But I didn’t know of any way to bring in HD material with CC’s, apply a new lower third across the whole program, trim out black space, and maintain the CC data if it was present. I am familiar with “line 21” for SD, but I have no knowledge of HD CC data, nor have I worked with CC data before.
-The Real Issue
So I was wondering if there is any workflow for applying a graphic layer of video on top of captured HD video, and still preserve the CC data. Then lay it back to tape. If so what are the capture methods, and is it possible in Final Cut to add the said graphic layer without destroying the CC data.

I have heard of people cropping the 2nd video layer to a point in SD footage so that the line 21 data would still be present on the video layer below, but I don’t understand HD CCs at all. Im researching them at the moment. Thanks for the ideas guys. I’ll post my results. And please keep me informed of any new information.

Thanks,
Drew

if you were just trimming out black space, commercials etc you’d be fine …

from the Blackmagic Decklink HD webpage:
Access VANC Blanking Data
Capture and playback any line of blanking, using any of the top three lines of your media file. This lets you store test signals, timecode, subtitles and many other custom types of data.

…but laying that graphic throughout is what’s going to kill it. Just a thought, but if you have the hardware you might be able to utilse the Blackmagic’s Live Key application to overlay the graphic on your edit master and so bypass the render in FCP that’ll strip that important data.

With a Kona HD or LHe FCP preserves the CC without a problem. HD or SD.
