That's what I said.

As far as I know there is no way to maintian what's on tape. I guess I was mixing this in with another thread where the Nitris DX wasn't maintaining captioning but it turned out to be the record deck was not set to rerecord the anc. data. My understanding is the Nitris DX and adrenaline will maintain the CC anc. data for capture and reoutput. I believe there can even be some effects that won't mess it up. If that is the case perhaps the old wipe between the captured CC'd clip would work. If the Anc data which is on line 9 and 572 in HDCam in the vertical interval I wonder if the wipe effect is one that wouldn't effect the anc data. I don't have any HD decks or CC to check this on. Since the Anc data is recorded as metadata in the vertical interval the SD trick might work but I have a lot of doubts and no equipment to test with.

You need to reread his post John. He said the shot he will be inserting has no captioning. The question is can he leave the existing captioning on tape when inserting other video.

You need to check your deck settings to see if it's set to record Vanc CC. Check the HDCAM VANC Packet Select Menu for HDCam. You should set ANC1 to LINE1 (D) TO 09, ANC1 LINE2 (D) TO 572, ANC1 DID (H) TO 61 AND ANC1 SDID (H) TO 01. Al the other values are set to 0's . For HDCamSr check the HDCAM-SR META DATA LINE SELECT

Meta Data 1(1080) : Line 09

Meta Data 2(1080) : Line 19

Meta Data 3(1080) : Line20

Meta Data 1(720) : Line 09

Meta Data 2(720) : Line 19

Meta Data 3(720) : Line20

As far as I can tell this should allow for the proper recording of the CC anc. data. Whether your system preserves it in the Avid is up to the model. My understanding is it works in adrenaline and nitris dx. On an SR-5500 these are located in the "Others" alt Metadata menu. Not sure where on other decks but I believe the names of the menus should be the same or at least similar. Oh what am I saying this is Sony so who knows where the different engineering teams decide to put stuff.

I've had a few captioned HDCAM tapes with video hits and I replaced the bad video with a non-captioned source. You'll probably loose the captioning for the shot you're replacing and maybe for the following shot. So I think (not positive) that the captioning information slightly precedes the picture/audio. I'm not sure by how much (SD is usually between 1 and 2 seconds, I would think that HD may be slightly less). Also, the first line of captioning after the insert point may be slightly garbled. But after that point, the captioning should return to normal.

I've only done this about 3 times, so I can't be positive of your results. Obviously, it would be best if you could make a clone before you experiment.

It will screw up your captioning. Don't do it.

Apparently you can turn off the CC data coming into the deck, but I don't know that means it won't blow away the existing data.

Okay, following this thread and other reading, I'm still not certain I can insert picture on a captioned tape if there are no captions on the shot that I'm fixing? Is the data in the compressed stream on HDCam "in line" with the picture? If I just insert picture with no data does it screw up the captioning information after my 3 second insert shot?

I've got a post supervisor telling me to do it but I'm not sure.

You cannot wipe the CC. It ISN'T part of the picture. It is metadata that is dragged along.

We're you ever able to edit the captioning? Meaning, if I cut to a shot that has dialogue, then the CC for the dialogue probably precedes the video by a second or two. So to preserve the CC, you would need to wipe in the CC on the outgoing shot. This is pretty easy on SD since you can see the CC signal. But on HD, (AFAIK) there is no way to see the CC.

Were you ever able to do this with HD material? Or is that wipe on the outgoing video considered an effect, and thus it makes editing CC impossible?

I know it works because I did it once. I have stuff written down at work on how to do it.

I'll try and post it tomorrow

I never got it to work in testing. Since it wasn't going to really work for our workflow anyway, I never followed up. :-(

Hi TCurren,

I"m attempting to ingest a tape with CC using DNXHD 194 adrenaline which is supported. Using the console I assured embeddnxcc was on but still nothing? Any ideas. Have you had to adjust any of the other settings like slots etc...Media is basic cuts nothing else.

tks

I'm confused. You want the CC to carry out via the export to another system and survive transcoding?

I would rate that Highly unlikely!!

The CC capture in Adrenaline only works if NOTHING is changed in the media and sent back out to tape. The slightest change, like adding color correction, adding a dissolve, etc. kills it. That leads me to believe it won't be going out on export.

Hi,

I'm working on an AVID adrenaline and digitizing HD Cams that have Closed Captioning. How can one tell if AVID has captured the Closed Caption from tape?

My ultimate goal is to ingest HD CAM with CC, export a DNX145 and drop that file to a transcoding system. One of the key things here is for me to know wheather or not the actual CC is being captured from the tape.

Thanks,
