View Full Version : Do you prefer capturing/encoding under VfW or WDM?

Hi,

Any preference or advantage of using one over the other? I have both operating systems: Win98SE with VfW drivers and WinXP with WDM drivers.

I've been using Win98SE with VfW drivers for my ATI card up to now for both video capturing and encoding. Image quality has been fine and the 4 gig limit with FAT32 hasn't been a problem. However, I know that VfW is an older driver format and Windows has since moved on to the WDM format. Does this provide improved image quality or enough of a reason to switch?

I haven't performed any comparisons yet between the two but wanted opinions by others who may have.

Thanks.

I was sick of using a wrapper in XP, so I dumped capturing in VDubMod in favor of VirtualVCR. I have found that I have a lot less dropped frames. I'm not sure whether to attribute it to VirtualVCR, WDM, or both, but I am happy with it nonetheless.

Something would be wrong if that was not the case :) VirtualVCR resamples the audio instead of dropping frames to keep sync.

The difference has to do with driver problems, which applications you can use, audio sync, stability etc. etc., but the final quality will be the same.
