Another Newbie Question

Is AVI the only format that VV3 renders to that is DV? I'm confused. I thought that an avi file was a compressed file. In fact microsoft doesn't recommend it any more from what I'm told. What I want to do is to capture and maintain complete uncompressed DV format and render the edited video as an uncoompressed DV format. I'm then printing to tape and handing it over to clients who then archive them on DVD. They have been experiencing clicks and pops in the audio and are concerned that it might be the avi issue with vegas. Can anyone clarify how Vegas can do this?

Once again. Thanks for all your tremendous help.

I'm not an expert but I can tell you a few things.
An avi is audio-video interleave, but there is no set compression for it, you can have avi files with many types of compression. (divx, etc) or uncompressed avi's.
To render to mpeg however you need to purchase the mpeg encoder.
If the sound is messed up then that is an issue of the audio compression you are using, such as mp3 or wma.
If you want uncompressed quality, use uncompressed avi or a lossless codec like mjpeg, for video, and .wav audio.
This should result in no loss of quality.
Also when capturing etc, make sure the system is "stable" to avoid lost frames etc.
hope that helps, maybe someone can help further.

Hi Scott,

FWIW, AVIs may be compressed at any level or not at all.

DV is compressed at 5:1... when you render in Vegas; if you render to DV without FX Vegas will just copy the data bit-for-bit... *with* FX, the recompression is completely transparent.

re: The audio issue... do you hear the clicks in your rendered file? If not, the issue lies in your client's DVD authoring app. You might be able to help them by changing your project's sampling rate: say, changing from 44.1k to 48k.

Thank you Marty & Kyle,

Your knowledge base is quite broad. I'll make those changes to the audio to see if their might be a resolve to the problem. I guess I could purchase a DVD burner myself and archive these edits from my computer.

The other question that might follow up to this is; I'm using simple canon ZR40 for my print to tape and and my client is using a canon GL1. Would there be a differnce in the two cameras that might cause this problem? Should I look into a special deck to print to tape for standard quality?

Thanks again for all of your help.
