Posted by: bobby Jan 14 2003, 10:13 PM
I have captured a AVI with VirtualDubMod. Capture device is ATI AIW 128 pro. Settings: 352x288 UYVY , frames 25 , audio in CD format , DirectDraw acceleration enabled (both), noise reduction ON. I have captured from VHS.
Captured file is OK when I play it in every Player I have. Problem is I can't edit this file with VirtualDubMod without lossing in quality. If I save captured file with/without modifications in VirtualDubMod I losse every 2nd vertical line in a picture and some frames ( frame reports are OK in every utility, but I see that some frames are duplicated just to stay at 25 fps - file is like other files at 15-20fps). Please help me. Is'it a input format wrong for VirtualDubMod or I don't know how to work with it.

P.S. - sorry for my bad english

Hello, I moved your topic to VirtualDubMod forum.

Some suggestions:
- Use Huffyuv to compress your video when you capture.
- Turn off Noise Reduction during capture; instead, use NR when processing the captured file.
- Try VirtualDub to capture, VirtualDubMod to process.

Is VirtualDubMod reporting any dropped frames?

I haved a droped frames at full PAL resolution ( more tha 50% frames was droped) , but with 352:258 was no drops. My card was detected as Microsoft WDM image capture, is'it that OK?
I will try things you sugested. Thanks.

I have a lot's of trobles with Huffyuv 2.1.1 - some white tracks over the picture, a lot of garbage..
When I try to capture 352:288 YUY2 - than I have droped frames
I have a AMD Duron 1.1 GhZ , VIA KT 266A , Maxtor 40 @ 7200
ATI drivers 6.13.5016 and ATI MMC 7.6 ( slower than MMC 7.1 ).
I haved TV Tuner card with BT878 , and capturing in full PAL was OK. Something is wrong with ATI, but I don't know what?
