Video Capture Stops – Why?
I am trying to capture a VCR tape with Vegas 8.0 and I am passing it through my Canopus ADVC-300. I am trying to capture it as an AVI so I can edit it and I have tried Vegas and Windows Movie Maker. In both instances, the capture stops at about 5 minutes.
Nothing is running in the background, no screen savers are active, and I am capturing it to an empty 200GB 7200 RPM hard drive.
Any thoughts or help would be appreciated.
Thanks

Try capturing using this little tool:https://windv.mourek.cz/
And see if it captures your entire footage.Steve Rhoden

You can also try scenalyzer to capture.
Does it stop in the same place each time?
Is your disk NTSC or FAT?Steve Mann

“Does it stop in the same place each time?
Is your disk NTSC or FAT?”NTSC = A US standard for video
FAT = File Allocation TableI’m guessing you’re meaning is the hard drive formatted as FAT32 or NTFS? In which case I’ve always listened to my betters in this and gone with formatting to NTFS to make use of the LARGER, single file, capture. However, and having used FAT32 years ago for capture, with the chaining of 4 minute files, this should also not be a problem here. It’s a brand new empty drive. No, and I’m no IT engineer here, this may be flagging up a bad sector on this brand new drive OR something flaky in the capture stream procedure. I’d be formatting to NTFS and be done.

NTSC?FAT??
I can’t blame lack of sleep on that one.But, does it stop in the same place?

Drive is NTFS and empty. When capturing as an AVI, if I use Vegas, the capture stops around 5 minutes. If I try Windows Movie Maker, it captures to the end (about 1.1 gb), but when it processes it, the file does not play and its length says 4 minutes 56 seconds. I can capture using a compressed format (about 700 megs) and it plays fine, so I am confused.
Also, I tried the utility mentioned above and it also stops around 5 minutes.

Do you have “Abort Capture on Dropped Frames” turned on?
Find that (it varies in different capture programs) and turn it off then see what happens.
However,
ANY dropped frames is unacceptable. Your camera spits the data through the firewire at a constant rate (25 mb/sec, or 3.6 mB/sec). Its destination is your hard disk drive. If something in the data path clogs up the flow, then you will get dropped frames. Most of the time the problem is that the hard disk can’t write at that rate because it’s seriously fragmented or the processor may be busy doing something else and can’t get around to servicing the I/O protocol fast enough. Especially on systems with only one hard-disk drive. Antivirus programs frequently get in the way of a Firewire data transfer. A bad Firewire cable may be noisy, corrupting a data frame (AKA Data Packet), resulting in a random dropped frame. I’ve never seen dirty heads in the camera cause dropped frames. Data dropouts, yes, but not dropped frames. Similar but not the same.
In normal practice you do NOT want to turn off the “Abort Capture on Dropped Frames” or whatever your favorite capture program calls it. As I said above, ANY dropped frames is unacceptable.
Your video media should be on a separate drive from your operating system – not a separate partition (because that’s on the same drive).
For capturing DV tape, I always use scenalyzer live (https://www.scenalyzer.com/)
For HDV tape I use HDV Split (https://www.videohelp.com/tools/HDVSplit).RAID is unnecessary in my experience – at least for speed considerations. I routinely capture DV tapes through a dual-core laptop into an external hard disk plugged into a USB 2.0 port and never a dropped frame. 5400 RPM drives should be avoided because their maximum sustained write speed is not much higher (in general) than the DV data flow, but I have used 5400 RPM drives with mixed success.
