Hello,

I hope someone in the know can help me out here, i've just installed vegas 5 about half an hour ago. I clicked on an avi file and in the summary view i got information of the video specs but a message saying: Audio: Stream attributes could not be determined, although the avi file plays fine in windows media player,.

Can anyone help me here? am i missing codecs for Vegas 5.0 or a plugin?

Google "Gspot", it's a free utility that will tell you what the audio and video stream formats are within the AVI wrapper, what codecs are needed and if you have them installed.

i have Gspot and recently installed ace mega codec pack, gspot tells me i have the codecs for all avi files. Does Vegas have it's own folder for codecs or does it search for the codecs i've already installed?


And why do i have [ ignore this user] next to my name?

What does Gspot say the format for the audio of this file that won't play is?

For video, Vegas uses VFW (Video For Windows) codecs not DirectShow decompression as WMP does.

This is what the audio says, in avicodec:

Audio : 84 MB, 128 Kbps, 48000 Hz, 2 channels, 0x55 = MPEG Layer-3, Supported

and in Gspot i get a stat saying i have 3 possible codec installed

Video Codec..: DivX 3 Low-Motion
Video Bitrate: 915 kb/s
Audio Codec..: 0x0055(MP3) ID'd as MPEG-1 Layer

First, both these formats are compressed delivery formats (DivX & MP3). Vegas is an editor intended to work with editing formats such as .wav & .avi (video for windows not highly compressed video formats under the AVI wrapper such as DivX or Xvid). Mpeg, wma, wmv, rma and others are also highly compressed formats. Editing these types of compressed formats will further degrade these files as they get recompressed upon render.

That aside, is this the same file that you started this thread about? I see you have a similar thread on the video forum where you include some files open with just video and some with just audio.

This file seems the audio should open but not the video since it's DivX. Even then, I once installed one of those "all in one" codec packs on one of my boxes only to find to my horror when I launched VirtualDub that the DivX 3 codec was a hacked version. I immediately uninstalled the pack for that reason plus I was experiencing odd behavior in WMP on normal (not DivX) files such as the video going all florescent green or fuchsia immediately after installing the pack. Uninstalling solved it so it seems certain that was the cause.

That was the end of my DivX days, the funny thing was, it wasn't even the DivX codec I was interested in when I got the codec pack.

yes...this is the same file i'm refering to in this post, i've since posted another thread in video forum about other avi files that i'm having problems with the video and audio.
I'll try uninstalling the codec pack i installed and see what happens.

Ok...i've ininstalled the ace mega codec pack, i can now see that it recognises the audio but alas not the video,i'll see what Gspot says and take it from there.

Don't expect uninstalling the codec pack to allow you to open DivX files (in .avi wrappers) in Vegas.

If you insist on editing DivX files in Vegas you should go to the DivX site (divx.com or org) and do some research there.

This just about exhausts my knowledge of DivX, I don't have a need for it.

Ok, i've uplodaded a 1 meg file called '1megfile' , maybe someone could take a look at it and see why i can't get any sound from it, although it plays fine in any avi player i have installed.

I've now uninstalled ace mega codec pack, reinstalled vegas 5.0 and i'm now able to view the codecs installed as i got an error before when trying to view the codecs. Now vegas can see what format the avi files are in. Strange thing though, vegas can see my avi with a divx video codec and mp3 for the audio, when i drag the avi file to the timeline i get the video fine and the audio i get (building peaks) and a % bar bottom left but it fails. If i drag a stand alone mp3 audio file to the timeline i get no error, i only have a problem with audio that's within an avi file.
Can anyone shed some light on that problem for me?
