What sort of files are you importing? How are you importing them?

I am importing FRAPS videos using the FRAPS1 codec. They are pretty much uncompressed AVI files that capture my video/audio live during a "capture session" when I play video games.

When I go to use the file in Vegas, I do FILE > IMPORT > MEDIA...

And select the video. It goes through playback just fine (but no audio) and when I export, the video is fine, but no audio is there, even though I chose a render format that says 44Hz Stereo 16bit audio.

Let me also say, from my experience with Adobe Premiere Elements, when you drag a video to the track, it usually shows a video timeline and an audio timeline. I only see a video one when I drag the video to the timeline.

UPDATE - I just dragged in some videos made by friends, and it places an audio track in there like expected. Wonder how come it can't determine this video's audio track?

Because it doesn't support the audio codec that's is in the file. Can FRAPS capture to WAV or MP3? Whatever codec FRAPS is capturing audio to now is apparently not compatible with Vegas.

Really?

Oh man. I thought the FRAPS1 codec was just for video compression, but I guess it's for audio as well. I guess Adobe Premiere Elements 4 was able to detect it but Vegas can't. Is there a way to "install" the codec for Vegas to see/use in its list of supported codecs or am I SOL unless I can convert it?

I don't know the FRAPS codec either, but you could try using 'Super'. It may be able to transfer the audio to one of the Vegas audio Codecs.
It's free, but you have to go thru a small maze of pages to get to the download.
You'll have to google it. It's called Super and has a copyright 'C' after it. I think the company is called eRightSoft or something similar.

I'll give that a shot, thanks.

To give you an idea how bloated FRAPS1 codec is, although the quality cannot be beat, at 720x450 / 60FPS, a 1:08 video was about 1.4GB. HORRIBLE.... But sure is purdy, though. :)

First you'll have to discover what audio codec FRAPS uses, then set things up so that Vegas can use the audio. As far as I can see there is no technical information about the audio codec on the FRAPS website so you will need to discover this for yourself. Go to this site and download GSpot. This will allow you to tell which codecs are used in your FRAPS file, particularly the audio one. Once you know that you can either install the appropriate codec so that Vegas can use the audio in the file or, alternatively, convert the audio to something Vegas can already use.

Is there anywhere you can download a short (a few seconds would be enough) raw FRAPS video capture? There are a few sample videos on the FRAPS website but if you download them you find that they have all been transcoded to WMV so you can't tell what the original audio format was.

That's a neat tool.! I made a video and ran it through the program, and here's what I got:

Video
Codec : FPS1
Name : FRAPS Codec
Status : Codec(s) are installed

Length : 12.65s
Frames : 759
kbps : 15975 (No wonder it looks so good, that's a lotta data/sec! I had been doing 3Mbps)
Qf (???) : 8.218
Dimensions : 720 x 450
sar : 1.600 (8:5) (screen aspect ratio?)

Audio :
Codec : PCM Audio
Info : 44100Hz 1411 kb/s tot (2 chnls)
status : No Codec Required

Oddly enough, I freaking import THIS video into Vegas, and there's an audio track!

Are you capturing from a deck or right from the camera? That may make a difference. What kind of deck or camera?

Capturing from in-game on a PC.

For example, I'll boot one of my favorite games, Team Fortress 2, and then use the FRAPs program which runs in the background that will write an AVI file from the video and audio on the fly.

No camera or deck is involved.

OK, well that explains why there's no information on the FRAPS website about what audio codec they use - they don't use a codec but just record the raw audio uncompressed (i.e. PCM Audio).

What it doesn't explain is why you found no audio in your previous tests. Vegas should be able to handle PCM audio just fine, exacltly as you've found with your latest test.

What does GSpot tell you when you let it look at one of the earlier FRAPS files that were showing the problem?

Well, I deleted them all since they were all footage of long long ago. Every FRAPS movie I've been recording now seems to import the audio just fine (and it is as you say, uncompressed raw audio)

FRAPS was recording at about 20-45MB/sec for footage uncompressed. Ugh! I'm glad I'm able to convert that to a video that's only 8-10MB/minute. Thank goodness for compression! And thank you for your help. Guess it was just a fluke.
