If you are using XP and WDM cap drivers, get this software

[Craig Tucker]

The software is IUVCR (find it in the tools section) and is made for WDM drivers rather than VFW drivers.

I can capture at 704x576 YUY2 with no compression without dropping a single frame. That is a capture rate of 20MB/s

Virtual dub is still superb for editing but you cant beat this for capturing.

The reason I have posted this is because I have read many posts about people struggling with the VFWWDM wrapper with varying success. I used to drop 1 frame every 3 or 4 minutes with VDub and that was at 352x288, at 704x576 I used to drop a couple a second.

I also use iuVCR with a WinTV board and XP. I do, however, have a problem with the audio losing sync. It seems to be random. I can go 10 or 15 min. with no sync problem and other times lose sync after 2 min.

Yes, I have done all the things I'm supposed to do (defrag, DMA, etc. I've seen posts about iuVCR and this problem. It's also been blamed on a different clock speed on the sound card.
So far the video seems to get ahead of the audio so I separate the A/V and cut small portions (10th of seconds) out of the video at scene transitions but it's a real pain

I've checked out ShowShifter but the trial version won't let you convert from their proprietary format to avi. If it can't do that I don't even want to waste my time.

iuVCR is nice. I have one problem though. I can't seem to watch while I record. Is there just some sort of simple setting I need to put on to do this? I've been using PowerVCRII because it lets me watch while I record and I can still pull SVCD quality. Is there something I'm missing for iuVCR or does it just not do this?

click the smart tee or whatever for preview in iuvcr option.

If you select Preview BEFORE you start capture it will work.

You need to keep an eye on the average frame rate if it drops below 25 the you loose audio sync. If I shut most programs down running in the background I can maintain a framerate of 25fps (pal)
