Fun with VirtualDub

[Kooldino]

Ok, I'm close to giving up here...

I have a Leadtek Winfast TV 2000 XP, and I know for a fact that it can capture video at 640x480. Unfortunately, VirtualDub doesn't believe me. Whenever I try to select anything over 320x240, it tells me that it's unsupported.

On this same system, I previously had an ATI TV Wonder VE that could only cap at 320x240.

I'm running WinXP Pro, I have the latest drivers for my card. Anyone have any ideas on why vdub won't let me cap at 640?

[Kooldino]

Also, if anyone could tell me how to capture a video in virtualdub WITHOUT vdub having focus, let me know. :-)

[Kooldino]

Also, I've tried numerous different codecs, etc (both audio and video codecs), and it will still studder on occasion after I play back the captured file. :-/

can you capture at full res using the software that came with the card?

Do you know what capture chips is used one the card?

1-Yes
2-No...but I'll see if I can find out.

I'm mainly annoyed at the "studdering" issue more than anything else.

Here's a product link (if it helps)

When you are in virtual dub, can select differnet capture devices.

You might have a choice of devices depending on the drivers installed, eg compatibilty mode, or WDM device...etc

as to the stuttering, what are the specs of your machine, eg CPU, hardriver type.

on an older setups you might want try capturing using picvideo mjpeg and convert afterwards...

captureing the audio uncompressed has seem to work better for me on old stuff.

[Kooldino]

I only have one device under video->source, if that's what you mean.

I have an Athlon XP 1600+ on an (eek) Asus a7v133 (KT133a chipset), 384MB of CAS 2 PC133, a RAID stripe of two 80GB WD 7200RPM disks, G3 ti200, etc etc.

(eek) Asus a7v133 (KT133a chipset)

eek is an understatement

[Dr Mordrid]

What Greebe is 'ing over is that the VIA KT-xxx chipsets are about the worst thing you could use for video capture/editing because of their absolutely lousy PCI to host memory performance.

The only way it could be worse is for it to be in an ABIT mainbord or combined with a SoundBlaster Live audio card.

I have done some reasonable captures at around 640x480 using a kt133a (epox 8kta3) using a geforce vivo...but it takes a lot of fiddling..

first thing your system and capture drive are the same..that is going to cause the odd dopped fram here and there.

a 1600XP is quite reaonable but you will have to use a good codec(picvideo, or maybe huffy)

and Greebe and Dr Mordrid are right, kt133a's are one of the worst to capture with, but it can be done after a lot of pain...

I think AGP combo vivo cards work best on kt133a's because you don't have to rely on the %$# PCI bandwidth of the chipset, but if you use a PCI capture card...I think you might be screwed.

AGP Vivo or motherboard upgrade...

[Dr Mordrid]

MB upgrade is the better path as it will also help the performance of the other devices in the system. VIA's chipset issues affect not just video capture but also HDD and memory performance as well.

Excellent current alternatives include those boards with the SiS 745 or NForce 420 chipsets. The upcoming boards with the SiS 746fx chipsets should also be a boon to videographers.

Whaaaahaaa!!!
Good old 'Will Hay' strikes again.
I'm running a KT133a on an Abit motherboard and have a SB1024 Live too!
Whaaaaa-haaaa!!
And I wonder why I have problems
...I took your advice on 'need a second hdd' BTW, I have 2 x D740X 80GB Matxtor's on their way, with a RAID card.
Thanks,
Will

So the ATI 64mb DDR Radeon ViVo I risked £33 on might be the best upgrade?
(...I really didn't want to drop the RR-G!).

Well, I ditched my SB Live! a while back, just because of the busmastering hog. I have a modem in my PC that's not in use...that wouldn't eat up any bandwidth, would it?
