VirtualDub at 640x480

[twentworth]

I've been using an older version of VirtualDub successfully capturing at 640x480 using the Huffy codec. I just downloaded the latest version, and it gave me some message upon installation that my card (or something) did not support above 320x240. Now, I can't choose 640x480 because it gives me an "unsupported format" error.

Has there been a change in VirtualDub? Do I need to find an older version to use? Thanks.

your question is useless without knowing what ver of virtualdub & capture device you were using

[Torontonian]

Most probably you are using Win2K/XP now. If yes that explains your error.

[sommersby]

Had the same problem, went back to using the older version of Vdub.

[twentworth]

Yes, I'm using XP. Is there something about XP and VirtualDub that doesn't allow 640x480 capture?

I am having the same problem under windows 2000 with the latest version of vdub. Being a dumbass, I forgot to save the old version (think it was 1.3.5?) that worked for 640x480.

So what's the deal with Win2k/XP that they won't allow higher res caps?

And does anybody have an older copy of vdub that allows higher res? Figured that this wouldn't break the forum rulez since itz free.

thx!

i am pretty sure you can download older versions of vdub from his site, but if not they are real easy to find on the web.

Nothing specific to Virtualdub and XP but it may have something to do with your hardware. I have a Radeon 64 VIVO and can capture in XP at 640x480 no problem. There is another post on here somewhere thay may help that I read a few minutes ago. Search the forums with "virtualdub" and you may get something that helps.

I have a WinTV card, and I checked and you're right- its max capture is 320x240. I had been capturing at 640x480 to get the best quality before compressing to mpg or wmv format. Is it fair to say that I will not see any difference if I capture at 320x240?

[dirk67]

I have a WinTV Go under Windows ME and I capture with VirtualDub at 352x576. No problem. You will see the difference! Capturing all lines and deinterlacing gives you a much better quality than capturing every second line.

[twentworth]

The latest version of VirtualDub doesn't allow me to capture at 352x576, but I'm using XP. Maybe that's the difference?

Yes, there is. It's a wrapper.
VDub (and other older applications) uses VFW interface for capturing which is native in Win 95/98 (and probably ME).
But Win2000/XP don't have it anymore, they use WDM. So, old applications have to use VFW-to-WDM mapper from Microsoft, and I believe there is a problem with this mapper & WDM drivers for conexant bt8x8 chipset (conexant reference driver 3.1.2 which doesn't allow to capture more than 240(NTSC) lines in 2000/XP.

About Radeon. It's completely another song. It uses ATI’s RAGE THEATRE chipset, not bt8x8, so WDM drivers are different and not based on conexant bulls**t. Thus, radeon doesn't have this problem, but it has another - it has macrovision protection in it which does not allow to capture copyrighted movies, and worse thing is - this protections sometimes triggers on home movies! Wow!

So, do as I do: capture with another software (like iuVCR) or other progs uses DS & use VDub as an editor for high resolutions.

By the way, here is old version of VDub (1.3d) - check it, but I bet it won't help:

Try this Universal BT8xx WDM driver:
- Download it from http://prdownloads.sourceforge.net/btwincap/btwdmdrvinstaller4.6.0.zip
NOTE: You can also search for "BT848" in http://sourcefourge.net if you want ot seek for newer releases.
- Extract it anywhere and run the EXE file. Don't forget to read the README text, because it has lots of useful info.
- Then when using VirtualDub, you must turn "Preview" mode on, because "Overlay" mode of HiRes frames is not suported by hardware. So it's possible, like in ATI AIW to capture both fields of the frame.

NOTE: This driver is a God's Gift and far the best one I've tested. You can even turn FM tuning on using non-FM cards.

[twentworth]

The BT848 driver works - I can now capture at 640x480.

BTW, when I click the sourcefourge link that you provided, I get redirected to a porn site.

Sorry it should be http://sourceforge.net (without "u&quot.
