No audio track on opened AVIs

Geoff_Wood wrote on 8/13/2003, 1:30 AM
Have I missed a setting somewhere.

I have 2 PCs with Vegas installed. On one, AVIs open as you would expect, but on the other (home) the video loads , but no audio is displayed, or played (same thing happens V4.0b and V4.0d) On the 'bad' PC the same AVIs play just fine with audio, in Media Player...

Everything else 'audio' is fine on the 'bad' PC.

Not sure if this is the problem or not, but make sure you wait for the audio to complete it's building process. If you interupt it, you will lose the audio portion. You really don't lose it, you just confuse Vegas and corrupt the sfk file. Even if you open a new project, the audio will be missing. To fix this, just delete the sfk file for the clip (if the clip is file.avi then the sfk file will be file.avi.sfk).

No, not interupting sfk-building.

When going through File | Open, the selected files stats say :
File Type: Video for Windows
Streams : 2
Audio: Stream attributes could not be
Length: (no entry here)
Video: 320x240x16 15:000 fps
Length: 00.01:00.12

What type of avi file are you trying to open in Vegas that is only 320x240 and 15fps? That is only half the size and fps as a normal NTSC file!

Anyway, it appears that it is about 1 minute long. That's small enough to post someplace where I could download it and try on my system.

Let me know if you want to do that. How large is the file?

Sounds like its certainly not a standard AVI file. The issue maybe a codec that's on one PC and not the other or else on the PC that it doesn't work on VV is calling up the wrong coded.

That's what I was trying to figure out by getting the file. It maybe that the file was created with proprietary capture device using their codec and the other system does not have the codec installed as Farss stated. I have seen this before with ATI, Haupage, and Matrox products. You have to be careful what you set your capture files to.

"Audio: Stream attributes could not be ..."

Yes, as farss says - there's something about the audio part of the clip that can't be read by Vegas.

Isn't there something about PAL in Australia (and NZ I'm guessing) is not entirely compatible with PAL in Europe, when it comes to sound? Could that be it? Your one PC has a more accomodating (>internatioPAL) set of codecs than the other?

i had this exact problem, my avi footage had come from an iomega buz capture card (insert laugh here) and i couldn't get any audio, however, i installed a general quite popular codec (can't remember the name right now, but someone must know it, it's very popular and doesn't cost too much / relatively) install that codec and voila.

The "bad" PC is almost certainly missing whatever audio codec was used to encode the audio in the .AVI in question.

Download GSpot from http://www.headbands.com/gspot/ and let it have a look at the file in question. This will allow you to see which audio codec is required and will give you a clue where to look to download and install it.

Slight 'reset' here -

The AVIs are advertising segments put onto CD-ROM for advertising dudes to check out. Wound down to 15 frame and that frame size for filesize and restricted playback screen size reasons.

*** The very same AVIs open fine, with audio, on a separate Vegas PC (both 4.0b and now 4.0d), and they play just fine on both PCs with Media Player !!! ****

It sounds like you have a particular audio codec on one PC but not on the other. You could try comparing the lists on each:
Ctrl Panel/System/Hardware/Device Manager/Sound, video Controllers/Audio Codecs/Properties
