Tuning a new ATI AIW capture card installation?
I have two AIW cards that I acquired from devious sources (eBay) and installed in suitable systems. I verified that they had good display and were working, but Real Life intervened and I had to put them aside for a few weeks. Last night I tried using them in an actual capture for the first time, and I had some definite issues.
I read through the first four pages of the AIW Hacks/Drivers thread, and I intend to finish it later but I've got to run and do a video shoot. Right now I thought I'd ask a quick question and see if anyone can point me in the right direction. System #1 is an AIW X1800 PCIe card, an eBay special, built into a homebrew tower computer with decent specs for 2010...ASUS P5QPL-AM motherboard, 4 GB RAM, Thermaltake 450W PSU...which was downgraded from its original Win7 to XP-SP3 (I noted from the other thread that SP3 has "security" issues but that they can be disabled; as this system is air-gapped then pointers on how to do that would be welcome). The AIW card came without cables and I thought it was a bust, but svideo.com came to the rescue with a replacement VIVO cable assembly which fits and works great. (Output is 2xDVI on card, no dongle needed). System #1 has a great picture and good audio playback when displaying directly from the VCR input in VirtualDub...but when I went to go ahead and capture, lots of dropped frames (like half!) and an output which looks and sounds like something from Warner Brothers animation on a bad day. The sound was noticeably (like a second or more) off from the video. I note from this thread that using the integrated audio can sometimes cause problems; I have in my arsenal a new-in-box Xonar DGX PCIe x1 sound card which I bought for another project but never installed. Should this be my first resort to see if I can improve the situation? System #2 is not nearly so bad; it's built around an AIW 8500DV card and a Dell Dimension 8250 tower computer. Still, it uses the integrated audio and I had 5 dropped frames in about 15 minutes of a videotape capture. That I can live with, but if there's a way to tune the system for top performance I'd like to know about it...and I don't mind looking for a PCI sound card if that's what it takes. Anyway, thanks in advance for any help from the experts! |
I am in no way an expert. But I have read and reread everything on this site in detail. I just built a Windows XP machine with an ATI 7500 card and a Turtle beach Santa Cruz sound card. The two biggest tips i can tell you are to make sure you follow the setting in the thread titles: Capturing with VirtualDub [Settings Guide]
and make sure you turn off "enable audio playback" on virtual dub. This caused me a ton of dropped frames. Just follow every single step in that post. I went back through a second time when i was still getting dropped frames and found I had missed one setting and thats all it was. That's my biggest tip. And just read the posts by everyone on here that has already done it. I just followed what they did and bought the same hardware. Maybe I got lucky that it all worked. |
The updated VDub Settings Guide referred to is here: http://www.digitalfaq.com/forum/vide...-settings.html.
The guide also makes no apologies for mentioning that an external frame-level tbc is not a luxury when it comes to vhs capture, regardless of the capture software used. |

Other that that, buy a sound card. We're talking under $25 here. Buy this: http://rover.ebay.com/rover/1/711-53...2/183110338826 For ATI AIW system, that is the best one to get. Quote:
Otherwise, great guide. Something missing in there is also that some systems require DirectX be disabled. Quote:

You can have audio preview in VirtualDub if you either
(1) split incoming audio to separate inputs, (2) have an audio card with "what u hear" type technology, (3) when Win Vista/7/8/10 allows the full-time piped/previewed input (4) one of the few cards that actually allows it 720x480 4:3 lossless AVI from SD analog sources Not HD Not 640x480 I hate shooting video. Good luck with it. Problems are exponential compared to capturing. Different skills involved. |

Try the MS device, not the ATI. See what happens. I have to use the MS WDM at times. The ATI is actually the hardware in use, but the connection is through the MS WDM for the preview.
