Odd HDV Capture Problem

daryl wrote on 5/1/2010, 1:22 PM
I have a puzzling problem with capturing HDV, Canon HV-20 and XH-A1. Capture SD no problem.
When capturing HDV, at some point, maybe 20 seconds, maybe 50 minutes, the capture stream just stops, the time is still running on Vidcap, but the capture stops.
I can capture directly from the camera (hook 1394 to the camera, no tape) with no issues.
Any ideas? Anyone?
Win 7 64 bit, Vegas 9D 64 bit(and 32 bit, and 9C, and 8, all same problem)

Hello, I do a lot of the same type of work with HDV, albeit with different cameras.

First, I would go through all the (internal/HDV) capture program preferences and make sure nothing stupid is checked, like, fail capture on dropped frames! or fail capture on device focus lost, or lastly, when capture fails, stop batch capture.

Secondly, make sure you have an appropriate capture folder selected on a drive with enough room for your intended captured files. The HDV capture program defaults are not necessarily that well thought out.

Good luck, post us back if more problems,

Thanks wilgen! I have tried every option (and there aren't many) in the Vidcap options. I have tried capture to both my secondary hard-drive (my normal capture drive) and to the C drive.
I'm wondering if there it is possibly Win 7, I have read on Microsoft's site something to the effect of 1394 problems with high-data rates. Does data from a tape force more data flow than video directly from the camera (no tape)?
Microsoft's wording is no better than that from Window's 3.1 days.

If you really are using Vidcap then there's your problem.
The external Vidcap.exe is only for capturing DV, not HDV.
For HDV you have to use the internal capture, unless of course your camera / VCR is set to downconvert to DV orpossibly you have it in Auto mode which will confuse any NLE.

You could also try using HDVSplit, seems to work better than Vegas's internal capture and its free.

The datarate from the camera is the same 25Mbps regardless of you capturing DV or HDV or anything else.

Reading your original post again, you could be having an issue from major errors on the tape or you've got a section of blank tape which is confounding the capture utility. Always a good idea to hook a monitor up to the camera / VCR's analog outputs so you can see what the camera is playing from the tape.

DOH, my bad, of course it is not Vidcap, sorry.
I used to use HDVsplit, but it would not work on this machine. Do you know what the current version is farss? I'd really like to get it working on this machine, I always liked it.

No Windows 7 support listed :-(

yeah, I think that's the one i have, dang.
Any thoughts as to why I can capture from a live camera, but not from a tape in the camera? Anyone?

hi mike,

hdvsplit working here under 7/64bit!

you warming up up there?

I'll try HDVSplit again. Just installed a new Roxio app, with HDV capture cabability, it too failed just like Vegas and Premier.
Looking more and more like a Microsoft problem, I have read about a 1394 problem with it hosing up at high data rates.
I will research it some more, but the MS site is not very friendly.
