capture is lagging!!!

[edgelett]

Hi all - I'm trying to capture video using this guide:
https://www.videohelp.com/forum/userguides/160618.php

I've used this guide before & captured from a handycam without any probs. That was 2 years ago when I first got my PC.

PC is: amd athlon 2.4
MSI GeForce 4 TI 4800 with 128 meg of ram
Creative SB Live! 5.1
1028 meg DDR ram
120 gig hard drive.

When I capture a clip, the video is lagging behind the audio. I looks terrible. i get this problem using virtual vcr, virtual dub, avi_io, windows media producer & intervideo media producer. I have tried capturing with different frame rates & video size, all have this lagging problem.

After reading the archives on the boards, I have done all of the following.

1) De-fragged both drives
2) uninstalled the NVidia WDM drivers & re-installed the old 1.08 driver
3) downloaded & run a reg cleaner & compressed the registry
4) looked at my computer/device manager/resources by type/inturrupt request....both the video card & sound card are PCI(19). I have NO idea what that means, other than apparently the video & sound cards are meant to have different numbers.

Can anyone help me here? I'm going NUTS!!!

In Aussie, the video is PAL. So, you must set your capture frame rate to 25.

That was the FIRST way I tried to capture...as a PAL video, with a framerate of 25 - video lags.

When that didn't work I tried capturing with different framerates, same deal.

But yes mainly I have been trying to capture at a framerate of 25 & keep getting this lagging problem.

Go to your window device manager and check your hard disk if it's set to DMA mode.



If you are capturing from analog source (not via firewire), then you need to install a codec. PicVideo MJPEC works best for AV_IO.

I've seen this in my PC when I connected the audio to the wrong input. I have a PVR-250 and accidentally used the motherboard's line in rather than the audio port on the PVR card. Once I used the correct ports, the problem disappeared. I know you have different hardware but perhaps you need to do a sanity check.

How do I do that? can you talk me through it step by step?

I'm using the morgan codecs as recommended in the guide provided. I'll give the pic video one a go though & see if that helps.

I garruntee I am using the correctinput mate - I'm a musician so I have a cable permenently plugged in to my line in on my soundcard.

well, I just did the following - uninstalled & re-installed my video card & all drivers, then captured using the picvideo codec instead of the morgan one...no problems.

thanks for the help!
