Audio Playback Problems in Vegas Video 3c

lowbellie wrote on 9/3/2002, 2:03 PM
Short synopsis:
Playback stutters/dropsout during playback of 12 audio tracks.
Original project began in Vegas Pro V1.
Using effect plugins Revalver and Antares Mic Modeler per track basis. Waves on FX loops.
Playback stutter doesnt happen on solo track playback.
Stutter begins with multiple track playback.

System
P3 667EB, 133Mhz, 256 RAM, Win 98 SE, IBM Deskstar 34GX 20.5G 7200 RPM

SF playback buffering set to max at 1 sec.
Disk drive set with DMA

Any assistance or insight in how to solve this problem would be greatly appreciated.

Regards, Lowbellie

I'm having this problem as well, after transferring v1.0b projects to v3...Many that played back perfectly in v1.0b will not in v3...v3 appears to hog up more CPU headroom than v1.

You're essentially out of CPU, best I can tell. I've found that DECREASING the playback buffer to around .3 seems to make things markedly better since you stop using so much RAM overhead for buffering and more for processing byproducts. The drive should still be yawning at just 12 tracks...let it do some more work.

Otherwise...You'll have to prerender tracks to keep moving forward.

Thanks. I'll give it a go. Time to get myself a new machine.

I am having the exact same problem. I am running winxp on a PIII 1.2 gig with 512 ram. also running seagate cheetah 10k ultra scsi drives sync'd at 80mbit per second.

I have found that if you remove the waves plugins from the project it corrects the problem for the most part. This is deeply disturbing to me as I enjoy using the waves plugins.

If I can't get this problem corrected I will have to roll back to vegas pro.

Anyone found a solution to this yet. and I don't want to spend all day pre-rendering files. This app should run just fine and dandy on my system. Vegas pro did!

I moved from 1 to 3 with no problems, all of my v.1 projects loaded and played, although they needed to be saved afterwards in the new native format. I've found that vegas 3 needs to have its media recorded on a hard drive separate from the system disk. I don't know why this is although I have theories - I started doing this from version 1 on, however I recently made this suggestion to a friend who had the exact same problems in v.3 described above, and saving media to a separate HD solved it. If you aren't doing this, it's probably worth a try.

FWIW,
