Capture specs for nvidia 4600 card

[charleson]

I am capturing analog tapes through an nVidia 4600 card (MSI's product) and using Ulead DVD Workshop. Everything is working fine (got that white band problem solved with the 1.08 capture driver).

I find that capturing without MPEG encoding at frame size of 640x480 (Ulead's default setting) creates an avi file of 100GB for 1.5 hours of tape. I'm new to this. Am I doing something wrong? Should I be using the MPEG compression as I am capturing? I figured I would have higher quality with the avi file but since I'm capturing from analog tapes maybe this is a moot point.

I'm having a hard time figuring out what the capture specs are for the 4600 card. The software says to match to the capture card's specifications.

Thanks for your help. This forum saved me a lot of frustration with the white band issue.

If you're getting such large file sizes for AVI files, then you're probably capturing to the uncompressed AVI format... Think of it this way, 90 minutes x 60 seconds/min = 5400 seconds. 5400 s * ~30 (roughly) fps (or whatever you're using) is 162,000 individual pictures/frames where the file size for each frame will be roughly the same as a bitmap.. thus uncompressed. Each frame at 640x480 is probably around half a meg (estimate) and thus, 162,000/2 = ~81,000 megabytes.. or 81 GB..

I may be wrong on this (as I don't do any capturing yet.. still new to playing with video toys on computers), but I would imagine that you're supposed to capture to a compressed format.

My advice is to dump the Ulead Software. The Ulead software requires you to capture UNCOMPRESSED files and these are HUGE. After you capture the software allows you to compress. It's bascially useless for anything larger than a few minutes unless you have terabytes of hard disk space.

Solution: Capture with a program called iuVCR using a good codec. Try setting up iuVCR and getting it to work. It works fantastic on my MSI G4TI4600 VIVO card. The iuVCR program is designed for capturing in Windows XP using any codec you have available. After you capture you can post process the avi file in Ulead or any other software you wish. Try it. Its worth a struggle to get it to work.
