[OT] DV-avi compression
Sorry to put this general question here, but its hard to imagine a site with as knowledgeable people, so testing your patience a bit by coming with this.
Can anyone tell me if there is some known formula that tell how man times one can rerender a piece of dv-avi until it starts to show badly?
Or am really recompressing each time passing some scenes back and forth between Premiere pro and After effects (no dynamic link involved).
I know `Vegas’ is smart enough to know not to recompress something like that but not sure about the tools mentioned or if it may not even matter regardless, since the compression is said to be fairly light.

There was a post on one of the Vegas forums many years ago where someone took the time to do 100 renders with a DV-AVI file.
There was no difference between the original and the 100th render.
That says a lot about the excellent quality of the codec used. -

Keep in mind that the quality remains high as long as you don’t apply any FX to the original clip.

It is extremely important to point out that the codec that was used was the Sony Vegas DV codec. You will probably NOT get that kind of quality from Premiere Pro of After Effects. The Vegas DV codec is proprietary to Vegas alone. No other program can use it.
You may want to use a lossless codec like Huffyuv or Lagarith if you are doing a lot of rendering in other programs.
