fix me i'm stupid

I downloaded the DV Film demo (adds professional effects, 24fps was mainly what I wanted it for) and was testing it out, but on the first try, after I tried to add the effects, an error popped up and said-"AVI sound must be 48kHz Stereo, 16-bits/sample" Now, I know 0-nil about video/audio formats. I checked the properties...i found the audio to have 1024kpbs. I don't think that's kHz... but since I don't know anything I don't think what I think is legitimate. So, if I capture with a Canon mini-DV, what do i need to do to this to be able to get this to work? Hope I have given you enough information. Thanks in advance

Your avi captured with the SOFO tools will always be correct for use in Vegas. What did you capture the vid with?

Thanks for your response. I used sonic video capture. But I'm not trying to use it in Vegas, I was trying to use it in DV Film Maker when I got the error message.

You might be using an ASIO audio driver, most of them require the output to be 48Khz.
Go to project properties->audio and set the sample rate to 48Khz.

FWIW, audio can be recorded at a number of sample rates and nowdays usually at 16 or 24 bit depth. In short, the sample rate means how many times, how frequently the recording software took a snapshot of the sound's continuous waveform - 96 k is more then 48 k is more then 44.1 k. The more samples taken, the better the file on your PC matches the original sound, but on the downside, this also increases file size. Think of bit depth as it relates to graphics stuff - 24 bit color on your screen vs 8 bit (256 color). More info is stored or available.

DVDs, CDs, VCDs, all have specs that call for specific types of audio files - the DVD spec calls for 48 k / 16 bit - some DVD authoring apps will convert it for you. The 1024 kbps refers to the rate at which the sound file must be read off of the hard drive or whatever media it's stored on.

Semi-trivia... Many sound cards (ie: the blaster line etc.) run at 48K internally, so they don't do well recording at 44.1. ASIO drivers may suffer from compatibility issues with whatever soundcards, meaning they don't always have or allow all the features of the regular windows drivers. A 3rd party spec, they allow for some stuff you can't get going through the std windows driver model, & are normally used by specialized audio related apps. However, I don't believe they pose any restrictions, or rather the spec doesn't, so if an ASIO driver set only allows recording at specific bit depth and/or sample rates, this is more a function of compatibility/incompatibility with whatever soundcard.

TO your original ?, need to make sure to set the audio recording/capture format at the time of capture, or convert the file in any number of audio programs. Sound forge is cool, but I like Goldwave as an easy to use alternative.

Ok, the default Hz used in vegas was 44,100. My problem would make sense if I used the audio in Vegas and then rendered out, but I didn't. I was just using an AVI clip which I captured straight from the camera. I did use Vegas' video capture, so if the settings are the same that would be my problem. I couldn't find how to change the capture rate though. (Is it possible it captures by what the setting in Vegas is? So if i changed it to 48k under project properties, would that fix it?) If I change the rate in vegas to 48k, and then rerenderd the audio that would solve me problem. Is there another (less time consuming way to fix this). I have an SB Audio Audigy DF80 card.
