Original "Data Code"

frazerb wrote on 8/25/2003, 7:00 PM
When one captures a DV clip into Vegas 4 and then prints it back out to tape, the result changes the the tapes Data Code date and time infor to the current time. This happens even if no filters or transitions are applied to the clip. In Premiere, the orignal Data Code date and time info is maintained unless a filter or transition was applied. Vegas does retain the original Data Code camera setting info.

Does anyone know of a setting that I can change to have it retain the original date and time Data Code material?

Frazerb,

This may not be too helpful, but here's a couple of things:

1) I think if you apply the Vegas Timecode FX to a clip in the Media Pool (as opposed to on the timeline), it will display the original timecode (not positive on this). You probably don't want it displayed, just stored, but perhaps wiser heads might know how to make this work.

2) search for some threads involving "timecode" or related terms. There were a couple not long ago from some folks doing deposition video, where timecode matters. Maybe there's a clue in there.

Have you tried printing from the capture utility? See what that gives you.

Thanks for your responses.

Jetdv, I have not tried printing from the capture utility, but that is a good idea.

Erk, I am not talking about Timecode, but Data Code, which gives the date and time on the clock at which the video was recorded.

There were extensive discussions on this board about the loss of original time (Data) code when edit. My need was for evidence in court. Can't cut and splice to save time since it changes the time code. So, people sit there watching hours of tape to get a few seconds worth of evidence.

Hi

I have excactly the same problem as you describe: I am interested in maintaining the Data Code, which gives the date and time on when the video was originally recorded...

I have read the answers you were given. But It seem like nobody could save your problem. Have you found any solotion?

No, I have not. Apparently few people are bothered by this, since most of the answers dealt with timecode and not the timestamp in the data code. Vegas is the only program I have found that does this. They maintain the camera info part of the data code, but replace the time info in the data code. Even if Vegas does not render the clip, the timestamp is replaced.

Ok, the time code stamp is not replaced - I made referance to this in a post where I was talking about timecode. The find was sort of a combination ofthings steming from another thread on the datacode subject. What I did was drop a VV rendered promo into the little datacode utility and I saw some interesting things - one was that the orginal date and time was retained through the render. This suprised me because there have been disccusions about online/offilne timecode and such. Here I had a promo that contained both orginal DV material that I had shot, DV material that had been shot by someone else but that was dubbed, material that was shot - dubbed - and than I dubbed, VHS material and titles. I had not really paid attention to all of this. I cut this promo a year ago so when I pulled it out and ran it through the date code some of what I found suprised me - here are some examples:

VV titles -
Dialogue: Marked=0,0:00:00.00,0:00:00.03,MainB,,0000,0000,0000,!Effect,{\q1}01/00/1900\N00:00:00

Betacam dubbed to Mini-DV -
Dialogue: Marked=0,0:00:10.97,0:00:11.00,MainB,,0000,0000,0000,!Effect,{\q1}25/45/2065\N45:85:85

Mini-DV > Mini-DV > Mini-DV -
Dialogue: Marked=0,0:00:29.49,0:00:29.52,MainB,,0000,0000,0000,!Effect,{\q1}09/11/2001\N08:04:39

VHS dubbed to mini-dv -
Dialogue: Marked=0,0:00:41.90,0:00:41.93,MainB,,0000,0000,0000,!Effect,{\q1}06/28/2002\N21:33:58

Mini-DV source-
Dialogue: Marked=0,0:01:32.42,0:01:32.45,MainB,,0000,0000,0000,!Effect,{\q1}11/09/2001\N10:05:33

VV rendered titles -
Dialogue: Marked=0,0:04:39.31,0:04:39.34,MainB,,0000,0000,0000,!Effect,{\q1}02/27/2002\N13:18:38

Ok - so this is just a little sample. But this was a render so where the date and time info was present it *did* retain this info. The VV rendered titles had the wierd date of "01/00/1900" for the first ones and "02/27/2002" for the last ones. From what I recall they were done on the same day. the betacam dub was a bt strange as well - "25/45/2065" for that date - but on the other hand this could be userbits in SMPTE TC that were read and retained on the mini-dv dub.

Now this was a straight mini-dv project. In a 30i > 24p project - this same info is not retained as far as I can tell. Also running it through AE via the satish frame server wipes clean the datacode info it seems. And something else I have found - anything captured or rendered in premiere will not read in VV - no timecode, no date, no record time. This exact same file *will* read fine in other programs such as Sclive. So - as long as you capture in either VV or Sclive and render the same type of file out of VV all info is retained fine. Adding filters doesn't seem to change info but I have not tried every single filter and rednered either. I would gather that if your render changes the frame/field than you would loose datacode info.
