Vegas Capture - will not stop stuttering (A&V)

Hello

I had this problem with my last capture, but using "capture tape" got rid of it. This solution doesn't work now.

What happens is this: I will bring up the capture window, play the footage, and both the audio and video stutters at the same time. The latest footage I have has industrial fans in the background so it's very easy to tell. It'll go "raaaaaaaaaaaa-ta-ta-ta-ta raaaaaaaaaaa-ta-ta-raaaaaa" (the "raaa" being ok, and the "tas" being the stutter) and will stutter the video along with the "tas." Because of this, I believe it's an audio-driven stutter that affects the video.

This doesn't happen if I play back through my TV.

It happens with both my deck, a dv53, and through the DVX.

I changed my pagefile to another drive (not partition) from my video drive and that didn't fix it. I have my prerendered & temp folders on the video drive, and tried it on a different one.

My computer is a P4 3.2C (Northwood 800FSB HT, not overclocked) on an Abit IC7-G and I have a gig of Corsair XMS-3200 ram. All drives are 7200RPM IDE on an ATA133 card. I have never had HD performance issues.

If I capture through Windows Movie Maker, it works fine (is this the same result as capturing through vegas? even filmed at 24pa?)

My footage is 24pa, and my volume was monitored and at an acceptable level. Onboard audio, no mic.

I use a belkin firewire cable and I tried two different firewire connections (directly on board, and from PCI firewire hooked up to board).

edit: I do not run antivirus software automatically, my XP installation is fully tweaked (14 default processes) and spyware free.

What do you think?

yes, that is the question, does it drop frames?

My PC did this at the start but Vegas never dropped any frames and the captured footage worked fine. My PC doesn't stutter anymore... never found out why, it just stopped.
 
No dropped frames, or should I say, no reported dropped frames. I should've said this in my initial post.

It's a straight out millisecond halt. It continues, and the audio remains in sync.

The captured footage doesn't work fine though, it retains the stutter that's in vegas.

Here, I'll post an example, hang on...

What's wrong with the footage? Seemed to play fine to me. I watched the movement of the truck, the tree leaves, and the fans. No stuttering as far as I could see.
 
Turn up the volume really loud, and listen for the stutter. When it stutters, you'll see the trees flicker.

Unless of course, there's an even bigger problem with my PC and the footage is actually fine...

and thank you for your help with this.
 
I just taped my TV for the last 15 minutes with monitored audio, only a few periodic pops.

This leads me to believe that my audio was too high when I recorded the footage earlier today (and a tad too high when I just recorded the TV). I really watched it, but I'm not ruling out the possibility that I made a mistake and didn't leave enough latitude in the volume.

Could anyone tell me if they experienced my same symptoms in capture with audio recorded too high?


EDIT: NOPE. I just recorded more TV with the volume set low. Still got the pops, though they do increase when the volume is increased.

I bet I have a bunk firewire cable. That f'ing figures.

I have an external storage HD that is firewire. Sometimes, but only sometimes, I experience what you describe when capturing by firewire. By unplugging the HD firewire, the stuttering stops.

It could be a bad cable, if you've ruled out another firewire device on your system competing for the system resources during capture. Just my 2 cents.
 
I had a similar issue when I was recording voiceovers not long ago, no video was involved. But what solved it was using the USB 2 plug on my external drive rather than FW. I don't know the technical reason but it solved the problem.

Hi Steven - do you mean, USB for the external drive you captured to? Because I'm capturing to an internal.
 
Yes, I use an external drive so I can carry it back and forth between work and home. It has FW and USB, so I just switched to using USB and it's been fine since.
 
Fixed.

It was my deck.

The reason my DVX produced the same results as I mentioned above is because the clip I tested with the DVX had the audio recorded too high. The one clip.

Now the deck is even doing it on the TV. The DVX offloads fine.

Now if you'll excuse me, I'm going to go to sleep for three days.
