recapturing problem...again

jimingo wrote on 6/22/2005, 12:17 PM
A few months ago I posted a problem with recapturing. When I recaptured my media, there was a slight timecode shift that effected every clip. After reading your responses, I came to the conclusion that it was because I was capturing from the begining of the tape and there could be some kind of timecode break at the very begining of the tape (aside from my own business, I edit weddings for a prod company, and their shooters do not put bars in the begining of the tape). Anyway, since my problem a few moths ago I never had the need to recapture anything until now. I started my capture on these tapes at about 4-5 seconds into the tape so there would be no timecode break in the begining, and I let the tapes capture all the way to the end. I recaptured one of the tapes and replaced the old version with the new recaptured tape, and there is the timecode shift again. The tape was not captured at the same in point as the original tape (I started capturing at about 4 seconds instead of 5). In my edit details window, the timecode for a clip on my timeline shows that it starts a 00:13:23:07. When I replace it with the new captured media, the timecode shows that it starts at 00:13:24:07. Why is this?? The only way that recapturing would work is if vegas used the correct timecode but it doesnt! This has been happening to me since version 4 and it happens on different computers. It seems as if vegas needs to recapture the tape from the exact same point as it did with the original tape but this doesnt make sense to me. It should go by the timecode, not the in and out point. For example if I put an hour long tape in to my computer and only used the last 5 minutes of the tape, I should be able to caputre just those 5 minutes and replace the hour long video (in my media pool) with the 5 minute video I recaptured and the edits on my timeline should be exactly the same. But this is not working for me. Is anyone else experiencing my problem. Please help.

I just read my post and it's really long and confusing so I am going to ask a more simple question. When you replace media in your project (that you are using on the timeline) with other media, does vegas match up the timecodes. For example, where 00:00:10:00 is in your original media, after replacing it with new media, will the new media's 00:00:10:00 be in the same place as the old media's 00:00:10:00 used to be?

Are you sure you have recorded valid timecode on your tape? It may just be using tape time.

yes, I used valid timecode, not tape time...I even check now that the timecode is the same in video capture as it is on my camera.

Are you capturing the tapes manually and replacing the original file with the new capture, or are you using the Recapturing facility within Vegas?

The former will probably not work, but the latter should.

I tried manually capturing and then replacing. Why wouldn't that work? I am trying to recapture using the vegas utility now...the reason I didn't do that in the first place is because whenever I tried to recapture using the vegas utility, the progress bar would get to 99% complete and would never reach 100. This resulted my clips being off also. I'll let you know if it is sucessful when it gets done recapturing but could you tell me why manually replacing the clips wouldn't work...doesn't vegas just match up the timecodes?

Thanks

I don't know how Vegas references timecode based on a capture file, but I know you just can't replace one file with another. There is probably some other encoded information that Vegas needs to uniquely identify a frame and that probably gets changed on each capture.

I have had good luck with the Re-capture option in Vegas.

My tape is still being recaptured with the vegas utility but meanwhile, I opened my manually captured clip in a new instance of vegas, opened up my original captured clip in the same instance, and matched the frames up (the original clip started about a second earlier). I then dragged the new captured clip backwards past the loop point so that it matched the length of the original clip (so the end of the tape is actually in the begining of the tape for about 1 second). I then deleted the original media and saved my vegas file. I opened up my project and replaced the original tape with the .veg file and now everything matches up. So I guess that means that vegas doesn't use the timecode, it uses the in and out point of a clip when replacing media. Not completely sure though...

I recaptured using the vegas utility and this is what happened. The first tape captured sucessfully but the second tape said that there was a start frame verification error (even though it was at the right spot) and capture reached only 99 percent and would not complete. I stoped the tape and inserted it into my project anyway and it did work, although I'm not sure why it only reached 99% and gave me a start frame verification error. At least the timecodes are matching up, unlike when I was using version 4.

Actually, after review of my first tape that I thought was captured correctly, I found a problem. I noticed that vegas stoped capturing about 3 frames too early. This only effects one event on my time line (the event that was supposed to use the 3 frames that vegas didn't recapture) and is very easy to fix (just pull the clip 3 frames backward) but I don't understand why I'm not getting perfect recaptures.
