Rendering, AVI and loss of quality

colins wrote on 12/16/2009, 11:18 AM

I have rendered 3 Vegas projects to avi and assembled the 3 avi's into one main Vegas project ready to render out as one avi for input to DVDA.

My question is: will there be any quality loss doing this, rather than assembling the three projects into a master project and rendering that out to avi for input to DVDA?

It is easier workflow wise for me to do the first option so am hoping I get a positive result from your reply!

Using Vegas Pro 8.1

What kind of AVI? If it's uncompressed then there's no loss. If it's DV then there's probably no noticeable loss. If it's DivX then there's probably quite a bit of loss. If it's Cinepak then it's probably hopeless sludge.

Thanks for your quick response!

I am rendering PAL DV Widescreen uncompressed, so it looks like I can use this with no quality loss. Great!

There is no such thing as "DV uncompressed", DV is compressed 5:1 right out of the camera. Vegas will Smart Render most "flavors" of AVI files anyway. If you put the three AVI files on the timeline and then turn around and render them in the same format without making any changes (other than trimming), there will be no loss at all. It won't technically be a render, it will just be copying the files into one larger file.

Many thanks John. That's clear now.
