Problems Capturing VHS with HVR-2250 and VirtualDub
Hi,
I'm trying to convert my parents VHS home movie collection to a portable hard drive and DVDs for the future and I've come across a few problems, but for now I want to focus on my main problem: The captured video is "jumpy" bouncing around from side to side, with intermittent blue screens (I'm guessing inserted or dropped frames). The audio playback is also broken cutting in and out very frequently. There's also horizontal bar mismatch across the screen (looks like some sort of interlacing problem) Here is some info on my testing and setup. 1. I've installed virtualdub and huffyuv64 from this site. In virtual dub I can not access the format, source, or display options under video. I also can't select huffyuv as a compression codec (however in the windows uninstall programs, huffyuv shows up as being an installed program which I can uninstall). 2. I have a Panasonic 4 head Hi-Fi Stereo Omnivision VHS player connected via coax to a hauppauge HVR-2250 card. The card has hardware mpeg encoders, but other forums report it capable of avi capture in virtual dub with no problems. 3. I've installed the latest drivers for the HVR-2250 and my nvidia video card. 4. I have tested video capture with the Dazzle DVC 150 from pinnacle. Using this device the capture is great, the only problem is a image quality reduction (boxy when zoomed to fit the full screen etc.). This leads me to believe the problem is not with the VHS player. I've already spent 20 hours or so on this and am about ready to give up. Does anyone with more experience have any ideas for me? Thanks, Tyler |

Analog video is unstable and messy. Post-1980 TV sets were designed with this in mind, and would accept crappy signals and somewhat play them decently. A digital capture device, however, requires a perfect signal -- it won't simply overlook errors like a TV did. It can't, in order to lock onto the video and digitize it and store as a digital version. Read these related posts and articles:

I'd also ask what "format, source, or display options" are supposed to be, as there are no such named options under the Video menu (i.e., File, Edit, View, Go, Video, etc etc) Quote:
