I'm trying to digitize approximately 20 highly valued family videos from Hi8 and high quality VHS (TDK HDX) tapes. I've had okay results with a DVD recorder (and using a since pulled 9600 AIW card on my PC), but not quite as good as I would hope for.
I have a Hauppauge HVR-1600 tuner card in my PC with which I can record from the 20-some local digital broadcasts I pick up with a UHF roof antenna (I use WatchHDTV instead of the WinTV2000 packaged with the card). Knowing that it has an MPEG-2 encoder on board, I decided to try a capture with that and was not all that impressed.
However, I captured about 5 minutes of video with what seemed to be default settings on a standard installation of VirtualDubMod (1.5.10.2 build 2542) and was greatly impressed. Unfortunately, that 5 minutes of video was at 15 frames per second and 2 GB in size! When I set it to 29.97 fps the filesize accumulated even faster.
I've dabbled with VirtualDub in the past (even some flavor called VirtualDub Mpeg), but never felt very comfortable in that environment. Now, after seeing what quality of capture is possible I'm suddenly re-interested.
The problem is, I can't really afford these kind of file sizes, as a single 2-hour tape would consume well over 150 GB of space at 30 fps.
Am I doing something wrong?
Can decent quality captures be made without such huge file sizes?
What kind of settings would I use and what version/flavor of VDub should I use?
My ultimate goal is to get MPEG-2 files without much more than cut and splice editing. Is there an easier way to get there without losing too much quality than to capture to AVI and then re-encode?
Thanks for any help or direction-pointing!

use plain virtualdub and a suitable video codec-the picvideo mjpeg codec (Q setting 19) would suit your PC. you can also try HuffYUV or one of the other lossless codecs

In VirtualDub, is it possible to limit the bitcount (making that term up to characterize a bitrate) of each frame, or is that an unchangeable function of the capture card (raw stream)?
Thank you! -

They do have a few things you can adjust to make the file a little smaller. Slow compression --> smaller file. Fast compression --> bigger file. All settings will usually give larger files than MJPEG.
