dropped frames

Just bought a new computer.

Asus K8V-X motherboard
AMD 64bit 3200+
1 gig Ram

Running Vegas4

When capturing, at some point during a longer capture, Vegas will drop 40 to 100 framesand then continue capturing without a problem or lock up and dump the video captured. I can back up the tape (miniDV through firewire) and recapture without a problem. This does not happen on every capture, but it has happened frequently. Any Ideas?

Thanks,

Chris

Could be many reasons. Start with looking at things Windoz has scheduled to run periodically. I had major grief like this caused by SQL Server. Take a look at running processes in task manager.

Read John Meyer's and mine response to dropped frames
www.vasst.com/training/vegasfaq.htm
There are myriad causes for this, some Vegas related, most windows related.
For instance, try sizing down your preview window.

Okay folks.....

I spoke with my computer guy...he thinks it's a cache situation.

Here is additional info....first, refer back to origianl post and apply to output to tape. When outputting to tape, (through firewire to camcorder to VCR...I've always outputted this way and never had a problem with my old system) at somepoint during the out put, the video & audio will freeze, then "fastforward" to the correct place of the output and then run fine. Generally, it only does it once during that output.

The system seems to be duing the same type thing during capture, what I mean by that is it acts the same, except one way it's caoturing and the other is outputting.

Any Ideas? I need some help, please.

Another thing that can cause havoc - and dropped frames - is overheating. P4's left on a long time or large external drives in slim cases can overheat and cause dropped frames. Since I first ran into this, I now run an external room fan over my large external drives to keep them cool while capturing or rendering.

Thanks I'll make a note of that, however, that is not the case with me, the frames drop in the beginning, the middle or the end...no rime or reason.

Are you using on-board firewire? Although I do not have your motherboard... on mine I had to disable the on-oboard and install a PCI Firewire adaptor.. then all was well. It might be worth it to simply buy one and try it out.

You will find similar (and much more) advice in the other links provided in this thread. Unfortunately there is rarely a "simple" or just one answer to these problems so you will need to research the suggested links thoroughly.

Hmmm... your motherboard (Asus K8V-X) has the dreaded VIA chipset. In general, VIA chips and Video editing don’t go together. It’s not specific to Vegas, or Premiere, or Pinnacle, etc. Every one of those web boards has horror stories of users who could never get their VIA motherboards to capture, print-to-tape, etc. correctly. It’s pretty common knowledge in the video community to not buy Mobo’s with VIA chip sets. They may be better now and you may eventually get it work, but just a word of caution for next time. Go with Intel or SiS chipsets.

Here are just a couple of links on this web board with issues that involve VIA chipsets:

VidCap stops capturing: 2mins OR what it feels like??
CPU - AMD 64bit or Intel P4 HT
Blue Screens
Better firewire chipset

There are lots more if you do a search on "VIA chipset".

I found this link in one of them on a PCI latency patch for VIA chipsets that might help:

How many of the options did you try in the link that Spot provided?
