It depends. What format *IS* the AVI?

If you have DV-AVI and you render to DV-AVI and you've made no changes (i.e. added no effects), the file is actually COPIED so there would be zero changes. If you add effects/transitions/etc... there will be rendering required giving potential for loss but would generally not be visible - once again, "it depends" depending on your source.

The source is DV from a Sony camcorder ..

No effects or transitions .. Just trimming ..

I'm archiving home video, which I may render to DVD at a later date..

If you are just trimming and then render to the SAME format AVI (in this case DV), then the new file created is identical to the original in quality.

But even if you do have to render, the Vegas DV codec holds up very well quality wise. You will take your biggest quality hit when you render to the MPEG2 for the DVD, but this can't be helped, and in most cases, is not terrible.

But if you were to generalize the question, the answer is usually "No". Rendering AVI to AVI in most real world situations is not a direct copy. Vegas is just special because it can do this with DV AVI media and a few other formats as well.

Understood -
I'll be using Vegas..

AVI is a container .. Other environments might repackage it ...

Yep. all sorts of codec can be wrapped in AVI...yada, yada...ad nauseum.
