Muting audio helps dropped frames

tunesmith1801 wrote on 6/10/2009, 7:57 PM

I am using Windows 7.

When capturing using Capture Video in Vegas 8 I get dropped frames. If I mute the audio on the computer (not in Vegas) I can capture with no dropped frames. This works when capturing live or from the camera off of recorded Mindv tape. I upgraded the audio drivers but it did not help. I did not do this in Vista.

Any ideas?

What kind of audio controller? Onboard? Card? Outboard Firewire?

Stupid question:
What kind of drive are you capturing to -- EIDE or SATA?

I am using the sound card on the laptop. a Dell Vostro 1700

The drives are Segate Sata 5400 spin

2.4 mhz 2GB Ram

It just started doing this with the Win 7 install. I changed the power setting to "Best Performance" closed the internet connection and anit-Virus. As soon as I un-mute the audio the frames start dropping.

I may have found the problem. Vegas default in the audio preferences is 44.100 hz I changed this to 48.000hz and everything is good so far. I guess the audio card was re-sampling the audio from the camera.

I never have figured out why Vegas defaults to 44.1k as this is simply incorrect for video. I wonder how many people don't permanently change this to the correct 48k.

I just captured an hour of SD using Vegas and had a few dropped frames, then recaptured the same using another program and had none - and I found this posting.....

I looked under the audio preferences in Vegas and in the capture program - and did not see where you could set this default - could someone tell me where it is ? I am using Vegas 8.0c. Thanks

Project Properties, Audio Tab. Click on the box "Start all new projects with these settings." Click on Apply.

Yes. Sony should change this default. It should always be 48.

BTW, thanks for reminding me about this flaw. I have a new laptop and, under the terms of the license agreement, since I don't use that at the same time as my desktop, I put Vegas on the laptop. I just checked, and sure enough, I forgot to change the default from the 44.1 to 48 kHz.

Vegas obviously started as an audio editor where 44.1 was the correct choice, but never changed the default even after it became clear that a majority of its current users primarily use the video editing features.

First thing I do after an install is set my default project properties. That bit me a couple of times long ago.
