VirtualDub doesn't see my capture card

[briansmccabe]

I have a brand new ASUS TV FM card, and I can't get VirtualDub to see it. When I go into capture mode, I click on Video and I look at the bottom. My card isn't listed. The only thing listed is "microsoft WDM image catpure (Win32)." How do I get this prog to see my card???

thanks

VDUB sucks for capturing.

VDUB uses VFW drivers (old school Video for Windows). New capture cards typically only come with WDM drivers.

You can:
1) Download and install the VFW drivers for your card (if they evern exist).
2) Use the VDUB WDM wrapper program to emualte VFW drivers.
3) Use somethng else (like IUVCR or one of the free ones).

I use virtualdub 1.4.12(build 14328/release) and works great with my geforceti4200,doesnt need a wrapper either.

[briansmccabe]

that's another aspect of my confusion. My new board replaces a Hauppauge Win-Tv Go board, which was also a WDM- based board - BUT VirtualDub saw that board and captured from it ok. On top of that, ASUS' own capture sofftware doesn't seem to see the feed coming into the board either. I dunno what else to do. I've tried playing with the wrappers before, to no avail.

Maybe you have a driver problem,you should get some input with the default software,did you go to their site and d/l the newest drivers?

Gazorgan is talking out the side of his neck, even though he has 3 eyes he can't see the forrest for the trees, newer dosen't mean better. Byt as he did point out the wrapper seems to workflawlesslyfor most. And another point he was way off on is that Vdub is one of the single best programs for capturing video it has a ton of filters it is the video encoders top choice for editing and capuring. This I say from much experince.
Which OS are you using ?

[briansmccabe]

I'm using XP Home. I also have tried to install the newest version of the drivers available. I think what seems to be happening is that the Microsoft WDM Image capture driver (which I assume comes with XP) is the driver that the board is being associated with, and Vdub just doesn't care for that driver or something. I can't get the driver to become associated with the board, even though in the Device Manager it shows the driver as coming from Phillips, the company that manufactures the chipset on the board.

Capturing and editing aren't realated. Feel free to apply 4 or 5 filters in VDUB and learn the true meaning of 'realtime' encoding.

I use VDUB for editing/encoding all the time. I do not use it for capturing because it won't do timed captures nor does it does it like the WDM wrapper and my drivers. IUVCR is just as good for capturings, as are several of the 'free' vcr programs.

I run 30% CPU and get no dropped frames capturing to MJPEG, 50% CPU for Huffyuv all in IUVCR(which has filters). No dropped frames ever.
In VDUB I hit closer to 80% cpu in Huffyuv. Apply some filters and it's all over.

VDUB sucks for capturing.
2) Use the VDUB WDM wrapper program to emualte VFW drivers.

Would you be so kind as to be very specific how to do that!
Windows XP already has this wrapper installed - BUT how do I use it?

I have been using Vdub for capture on WinXP with a BT848/878 using the IULabs drivers for some time now, and am very happy with is. I once worked out how to modify it to allow capture at 480*576 (PAL) et al.I am pretty sure It was something to do with the wrapper.

Now i have formatted and reinstalled OS on this machine, and I cannot get it going again. I could use the BTWDM drivers from sourceforge, and/or IULab VCR but there are other reasons why this does not work for me.

Briansmccabe, I use a WinFast A280 card, and I have to open up its PVR capture software, then close it, before I open up Virtual Dub, otherwise Virtual Dub doesn't recognize my card. Maybe something similar is going on with you? Try opening up your capture card software first, then closing it, then opening up VDub!?

[marvel2020]

VDUB works for me 100% everytime. Using the WDM drivers.


The difference between VDUB and IUCVR....


iuVCR.... Payware, yes it has a timer recording option but this can be a real pain to get working correctly in WindowsXP, i heard that it works better in Windows 2000.

VDUB.... Free software, the ultimate in my opinion,
and with the VirtualDubVCR plugin you can have Timer recordings also.

Vdub and its many many variants (VirtualDubMod, VirtualDubModSync, ad infinitum) works incredibly well for capturing...when it works. The problem is that it doesn't always work, or perhaps even doesn't work in most cases.
It's not as simple an issue as just WDM vs VFW drivers. On some systems the wrapper works. On others it doesn't. There seems to be an interaction between the mobo chipset and hte OS and the card you're using that combines with VDub to porduce a situation that's impossible to predict. Various moderators on this forum have described the situation as "black magic," and that's about the size of it. You just can't tell which systems will work well with VDub for capturing, though the Hauppauge has a generally good track record while other cards like the Leadtek, or any firewire unit, are known *not* to work with VDub as the main capture software.
The immense number of useful filters certainly makes VDub a great tool for capturing if you can get it to capture with your card. However, at least 50% of the total number of prolems reported on this forum trace back to something involving VDub. Either you get sync problems or VDub won't capture, or won't capture at anything but 352 x 240 or even (in he case of my particular card) 320 x 240, or you get various weirdnesses like green screens or black bars or upside-down picture or other el bizarro stuff that involves really esoteric fixes like getting into your BIOS settings on your mobo and changing things like the RAM interleave.
Cap cards have always been feisty. VDub's age increases those problems exponentially. On some systems it may make more sense to install a dual-boot system with Win 98SE on an alternate hard drive, and boot into that to capture in Win98 and then reboot into Win 2K/XP for video editing & DVD authoring. (One of VDub's great strengths as capture software is its ability to capture seamlessly to multiple 4-gig files under FAT32 OSs, something that not many other pieces of video capture software support as well as VDub does).
It may be necessary, depending on your combo of computer hardware and OS and video card, to just bite the bullet and shell out $50 or $100 for another capture card that does work with VDub. That's an ugly fix, but there comes a time when you're stamping on bumps in the rug in some computer systems. Meaning, you fix one bug and another crops up somewhere else because of the fix. I've heard people talk about this on certain (not all) ATI card capture interacitons with certain computer systems & mobos & OSs. Eventually these people just gave up on the ATI card and moved to other capture hardware.
Now, for some people the ATI card works perfeclty and gives no problems. But for others it's slow torture. Same deal with VDub. ON some systems VDub performs flawlessly, while on others it's just a giant non-stop pain in the rear.
Alas, there are so many combinations of mobo + OS + cap card + VDub variant that there's no hard-and-fast answer to getting VDub to work peroplry as capture software other than hands-on trial and error on your particular system.

I use to believe the same thing for Virtualdub, that sometimes simply doesn't work.
Well, this is not true. The problem is that you have to dig beyond the installation to make it work. Dig and search a bit about it.
Example: After 3 freaking years, I manage to make my asus 7700 deluxe work with virtualdub on win2K. I concern that impossible without issues. Nothing is impossible, it seems...

My experience to the w2k users: Install service pack 4, do what the virtualdub site says about the installation on w2k, install the tweak wdm drivers and also install dscaler.

Run dscaler so to activate hidden stuff of your capture card (example: PAL 60, NTSC 50...) and then run virtualdub. That's it!

IMHO, Virtualdub is the best capture program. But not the easiest... From the other hand, it is free!
