Missing Audio

4110 wrote on 7/4/2011, 12:15 PM

I am trying to import an avi file into Vegas 10. Right after I begin the import process a message box pops up that says an audio proxy file is being built. There is a progress bar on the bottom left. When the process finishes there is an error message. The error details say that the audio proxy files was truncated at the point where the audio stream format changed.

When I drag the file to the time line the video is longer than the audio. The audio really is truncated part way through.

In fact, the avi file works in other applications. If I play it in Windows Media Player it plays just fine from beginning to end. The audio is correct all the way through and is not truncated.

How can I make this file work in Vegas? Are there some settings I can change that will make Vegas work as well as Media Player?

Thanks,

David

Where did the .avi file come from? What created it? How did you get it to your computer? What codec is used?

I just had a similar thing happen with an AVI file shot from a Flip...imported into Vegas 10d and...no sound at all. It wasnt my camera, so I don't know what audio settings it had, but like you, it will play on windows media player just fine.

The avi file was mine. It is video that I took with a Panasonic PV-GS400 MiniDV Camcorder.

I don't know what codec. How do I check that? I capture with Windows Movie Maker in Windows XP.

This is home video and I don't take an entire roll of film at one time. I film a little bit during holidays or vacations so a roll can last for a long time. I suspect that I changed the camera settings at some point.

Based on this problem I think that Vegas expects the settings to remain constant. To test that idea I forwarded the tape to the point that Vegas encountered the error and captured from that point forward. Vegas imported that file just fine. So I eventually got everything into Vegas OK. It just took two separate capture sessions and two separate files.

"I capture with Windows Movie Maker in Windows XP."

WMM captures work in WMM.
To the rest of the world, they are nonstandard.

Use the Vegas capture utility or Scenelyzer to capture your DV from firewire.

For your existing captures, "maybe" Avidemux will fix them.

I have some good news and bad news. The good news is that I was able to get the file into the computer and then read it into Vegas without an error. I switched from my old XP machine to my new Windows 7 machine and from Windows Movie Maker to the Panasonic software that came with the camcorder to capture the video.

The bad news is that I haven't been able to capture successfully with Vegas. There is a firewire port on the camera but if I connect the camera to the computer with firewire then Vegas doesn't see the camera. The Panasonic software suggests that the connection should be made with USB and that is what I used for the successful capture. Without changing anything about the camera and USB cable setup, I then switched to Vegas. Vegas did see the camera and captured a clip. The video was OK but there wasn't any sound. I guess it isn't critical that I figure out the Vegas problem because I do have the other solution. Still, I am curious and would prefer to do it all in Vegas if possible. Any ideas why I'm not getting sound?

Thanks,

David

Vegas will only capture through the firewire port. It won't see any USB camera devices.

Note also that any capture you get through USB will probably be a highly compressed "web video" stream rather than full quality DV. This is why Vegas doesn't use USB for capturing DV.

Sometimes in Windows 7 in order to get the Firewire to work you have to revert to the Legacy drivers.

Vegas does see the camera when the camera is connected with USB. Vegas will operate the camera controls (start, stop, rewind) and will record an avi clip. However, the clip only includes video-no audio.

How do I revert to legacy drivers?

I did an internet search to figure out how to switch to legacy drivers. I made the switch and Vegas still does not see the camera when I use firewire connection. So I am still not able to use Vegas to capture video.

When I did the search I found a lot of people having a lot of problems with firewire. I respectfully suggest that the Sony engineers add additional connection alternatives, especially USB, to Vegas.

Thank you,

David

This is the same problem for me. I game and record it with Bandicam, a free and reliable recording software. I make tutorials for one of the games I play, and I use a microphone while recording (bandicam allows me to record audio with a microphone while recording). Sometimes I mess up, and I'd like to edit these parts out. So I open up Vegas Pro, and start editing. But the sound didn't come in. Instead an error appeared (the one 4110 described). I tried to fix this using my status bar, because it says "You can cancel this operation by clicking on the cancel button on the left side of the status bar," but there was no button. I have made videos with Sony Vegas pro before (with imported media with audio) and have never had this problem until yesterday. I am very upset because I just bought this software and I am already having problems with it. The audio works when I play the video clips in Windows Media Player. I am running a 64 bit Windows 7 OS.

Tzsara,
would this help with Bandicam audio re Vegas
Bandicam no sound in Vegas
See towards the end of the thread there.
