Vegas 6 digital audio capture skipping

KB8WFH wrote on 10/30/2006, 7:31 AM

I am trying to capture video using Vegas Movie Studio 6 from a Sony TRV-310 digital video camera suing a 1394 firewire connection. The video is capturing fine with no reported of visible dropped frames. But the audio is dropping out just for a split second. I can see it on the audio track and the playback comes out stuttery and broken every few seconds. If I listen to the playback directly from the tape on the camera, the audio is perfect, no clips , breaks of pops that I hear on the captured track from the computer.

Nothing else is running on the system, and I even tried setting up the capture program to a higher processing priority with no results. System is P 1.2 GHz, 512 meg of ram and Windows XP (current version and service packs) and plenty of disk space available. Its recently been reformatted and e-installed and it doesn't need a defrag. I seem to get this problem at the beginning of a tape or a capture and fewer instances as the tape goes on. But as I said, it is not there at all listening to the audio playback right out of the camera.

Any suggestions?

I can't really tell from your post, is the audio okay AFTER you capture?

Is is just a problem during capture?

The audio is not ok after the capture. The problem with the skipping audio exists during and after the capture. What I am hearing at the time of capture is what is being captured. Playback on the computer gives me the same skipping effect in the same place I heard it do so during the capture.

Thanks for clarifying. This might not be a fix, but it might help. Have you tried turning off the option to hear audio during capture?

Although a 1.2 cpu should be able to capture, if you have a lot of other services (not programs, but services) running that might be interrupting the cpu during capture, it might cause some audio dropouts. By turning off the AUDIO monitoring during capture, you are eliminating another proces from the CPU to do list.

I will give that a try. Thank you.

I tried it with the option of no audio during the preview. No change in the problem. Audio still skips and pop on playback. Any other suggestions?

Also, I tried no preview audio or video. No change. The audio dropouts are really making my project video unusable. Any other suggestions.

First, make sure you are running the latest build of Movie Studio. The folks on the movie studio forum may be able to provide more help, as while Vegas and Vegas Movie Studio are very similar, they are different products. So you might want to check the VMS forum.

Second, lets eliminate a possible problem with the software and/or hardware. Go to www.scenalyzer.com and download the trial copy of scenalyzer, do a test capture with it and see if the audio issues are still present. If they are not, then you know it's a problem with VMS and you have a possible work-around. If they are still present then we know it's not a software issue with the capture software, and may be an issue related to your firewire card, or possibly your camera.

Most likely not a PC / software problem. Struck this on a few tapes over the years. Suggest cleaning the heads of the camera. If that doesn't help you best bet is to feed the audio from the camera / deck into your sound card and record that, assuming the analogue output from the camera / deck is clean. You may still notice that the audio is not perfect but hopefully useable.

After you've sorted that out you need to find out why your tape got recorded that way. Cheap tape, old tape, dirty heads or camera in need of service are all possibilities.
