can't open capture in virtualdub

[umair]

it keeps saying no capture device found. the capture card i have works fine. i have another software which sees it. i think virtualdub is looking for the pci capture card i had installed before. i removed that and put in a apg capture card which is also my video card. is there someway i can make virtualdub see where the capture card is?

[qwerty99]

i also have this problem. i tried to remove virtualdub and reinstall it but i'm still having the same problem. does anyone know how to solve this?

[dominic01]

What Capture card are you using?

[Double]

I know Vdub doesnt like ATI cards.
Something to do with the WDM (Windows Driver Model) ATI uses

-D

[qwerty99]

i have an ati. is there anything i can do?

[FOO]

Vdub is excellent but came before Microsoft changed their
video API. The old one was VideoForWindows which Vdub uses
The new ones uses WidowsDataModel WDM
If your capture card doesn't supply both kinds of drivers,
(like ATI) you have to use a "converter" - WDM wrapper.
It seems to have problems.- mainly speed. ...but..

I can now capture from an ATI card with good results with Vdub.
I am not sure what change fixed it.

But who cares. Capture with the ATI MMC. It works even on realtime
MPEG2 .

[Tommyknocker]

Isn't there another wrapper besides Windows'? Something like what Conexant's web site offers?

[FOO]

I wonder why you need to use Vdub.
If you want to capture something use the ATI stuff that came with
the card. It works better than Vdub.

[qwerty99]

the ati stuff doesn't work better

[FOO]

You may have to explain why you think that.
I believe you to be incorrect.

Right now you can't do it with Vdub or MMC how do you compare
zero to zero and get a winner

[qwerty99]

the quality doesn't look as good. i'm just going from the tests i did before when virtualdub was working

[Tommyknocker]

Time out, gentlemen. How about you show the rest of us some picture of the captures you've done with both cards. Then we can decide for ourselves. I still use Virtual Dub from time to time, and still find it very reliable with good captures. Of course, it is not DV, but soimetimes I do not or cannot use DV.

[FOO]

OK MMC will capture in MPEG1/2 or use any external
AVI codec.
Vdub will capture with any AVI codec

MMC has a WDM driver (only) Vdub does not

MMC can therefore go much faster than Vdub

Are we comparing apples to apples here ? Didi you use
the same codec for your captures with MMC and Vdub ?

There will be a lot of confused people here if you can prove that
Vdub can capture from an ATI card better than the ATI stuff.

[feenix]

Yep - FOO is spot on.

The only reason for using vdub for avi capture is if you're on win98/ME when you're stuck with a 4gb file limit as MMC(7.7 in my case) doesn't allow for segmented capture.

However mpeg1/2 does and the captures are every bit as good as an avi capture (with huffy or mjpeg) without any dropped frames.

[qwerty99]

using MMC is it better to capture with huffy and then convert to mpeg 2 or is it better to just capture in mpeg 2?

[FOO]

I grab a lot of movies from the TV, and since it's not excellent
quality to begin with I just capture directly to MPEG2
and edit out the commercials. and Author a DVD
Saves tremendous amounts of time.

Sometimes if I want to apply filters or kill logos
i do it the AVI way and encode. It's time consuming like that.

[qwerty99]

the quality probably comes out better the AVI way, right?

[FOO]

Not much unless you use filters. I have a fairly noisy
cable feed. I just hate logos

[qwerty99]

what are the good filters to use? do you do this in virtualdub? i got virtualdub working, i just changed my video card back to geforce and then back to ati and now its working.

[FOO]

You just have to play with all of them.
Vdub has the input window and the output window side by side
so you can see what the filter did.

Just get a movie and sit down for an hour and play.
Everyone has a different opinion. I kinda like the smart smoother
sometimes.

i just tried recording with both virtualdub and the ati software. i set the same standards for both. same video and audio compression, frame rate and video size. i did a test for 1min. the ati took up 275mb and virtualdub took up 282mb. but when i'm capturing with the ati it says that there is 48mins left and in virtualdub it says there is 1hour 15mins. shouldn't the ati have more time then virtualdub? is there anything else i need to set other than the video and audio compression, frame rate and video size?

[qwerty99]

i'm going to try using the new ati mmc. i was using the one that came with the card. i'll let you know how that turns out

[qwerty99]

actually i don't think that will matter. it said that the newest version was 8.6 in the tools. but when i went to download it the new version for my card, all in wonder 128 pro, was 7.2 and the one on the cd is 7.1. so i don't think it will make that much of a difference. i think i will have to buy the 8.1 version and then upgrade to 8.6, which i don't want to do. i'll just do some more tests

[FOO]

8.6 seems to have problems bad enough that I went to the trouble of
going back to 8.5

[qwerty99]

i have to admit that the ati is easier to use. is there anything else i need to set other than the video and audio compression, frame rate and video size?

[FOO]

Do not set IVTC or de-interlace ..... you will be sorry

[qwerty99]

i don't even know how to set that. but the video is still coming out bigger in file size through ati than through virtualdub. is there a reason why? would it be because it just the way the software does it or i'm not setting something right?
