HDV Capture - Clip Split problem.

farss wrote on 9/18/2008, 6:26 AM
I know many have raised this before. It's never bugged me because either I don't shoot HD to tape or when I do I'm fanatical about tapes and kit. Now I have to deal with many hours of tapes I didn't shoot and didn't get to coach the client before he set off on his numerous trips.
Probably the problem here is in part due to using whatever tape was on hand and general camera abuse. The client is a nice old director of some considerable standing from years ago, probably this is the first time he's used a camera himself.
So what I'd really like to know is why Vegas 8.0b splits tapes into clips when I specifically asked it not to. Splitting right in the middle of an interview is a bit of a problem given that I've got a few frames of mangled vision and lost a couple of frames of audio. Almost none of the splits are between shots, strange. For what it's worth Vegas reported no dropped frames during the capture.

Now just to be clear given the current tone of some threads, I'm not asking or demanding anything be fixed. I'm not angry or annoyed by this. For other reasons I might give this whole project the flick anyway. What I would like to be able to do is tell the client how he can avoid this happening in the future.

Now I know some are going to say I should use some other piece of code to capture HDV. I don't entirely buy this. From my experience playing out tapes from DAT to UMatic the second time you play them will almost always be better than the first. Simply running tape over heads can clear problems on the tape itself.

Bob I remember having this happen with HDV/Vegas capture - I've been lucky that the points where the clip breaks happened weren't in the middle of footage I needed, so I never had to solve it.

My workaround thought would be to recapture from just before the break to just after, and see if it splits consistently - if it doesn't then use timecode to "patch" the bad split with the second capture..

If on the other hand it splits at the same point, then the only solution I've heard, and never had to use, is try the ironically named "HDV Split" for capture.

I thought it was my camera ( HV3) and not v8.00 or 8.0a :(
I am getting indiscriminate cuts, losing 1 or 1.5 seconds of footage at the cut.
New tape, locked camera, continuous run to end of tape: Still get many cuts.

Most of what I have been shooting lately is concert footage; i.e. 45 to 55 minute unbroken takes with HV30 & HV20.

If I get a break when I capture (maybe 10% of the time), I try recapturing the tape again, usually this fixes the problem. After 3 captures giving me the split in the same place, I assume I have a dropout on the tape that is causing the split and there's nothing I can do about it - even if I could capture unbroken I'd still have a glitch at the droput.

Thanks guys.
Sometime ago I did record a 3+ hour concert to tape and the only time this issue arose was when there was a perfectly logical explaination, like the venue had a power failure.
I'll bring home one of our camera test tapes, it'll be interesting to see how that captures as our test tapes have been to dell and back.
I'd have thought some form of counter / error message from the capture code would have reduced the level of user frustration from this issue. If one had the money you could try capturing the tapes via HD SDI, then again if you had that kind of money you'd most likely not be using a HDV camera anyway.

I use HDVsplit.

I have mentioned for some time now Bob, that the Vegas capture utility is weak and problematic. It needs to be refined and upgraded something awful. It really is not on par with the rest of the Vegas software. I certainly have my ideas as to what it SHOULD be but that's another story. In the mean time, I wish SCS would recognize it as a weak link and bolster it up a bit.

I've noticed it too. I captured about an hour of footage and told it not to scene detect and for some reason it split the clip into a 3GB and 6GB file (the 3GB file was first so it's not like it reached any limit or anything).

I consider this a bug since I told it I didn't want splits. Very annoying.
