concerning ac3 rendering
i am using sony vegas 7.0e build 216 on windows xp sp2. is there a way to render ac3 audio, not separately, but in an avi or mpg file? when i select mpg as the output format, the only audio formats to choose between are layer 1 and 2. in avi, i can choose between lots of formats, but no ac3. why not? if i can render ac3 separately, then why not in avi? since apparently almost every other format supported by vegas can be put in avi? preemptive thanks to all.

AVI with what codec? Why would you want to? it’s not compliant with anything, and most systems that can play an AVI-wrapped file can’t play an AC3 file, and vice versa.
Could you please cite a specific example of why this would be beneficial?AVI w/AC3 used to be used heavily with the DivX codec (which Vegas does not support in later versions) as a pirate’s tool, but with MPEG 4, this has long gone the way of the dinosaur.
GordianKnot will help you do this if this is what you really wanna do.
Parting comment…Vegas is a tool for professionals and pro-sumers. It likely will never be coded to create designer file-types predominantly used by DVD rippers/pirates/file-sharers, and that’s where the avi w/AC3 format has been predominantly used. There is no place in a professional workflow (IMO) that would use this sort of packaging.Douglas Spotted Eagle

i have a music video in xvid and ac3 5.1 surround, in an avi wrapper. it is letterboxed, and i want to crop it to 16:9, which works excellent. but i would like to render the audio as-is, in surround, preferably in the same file as the video stream. it’s not a matter of do-or-die, i know i can mux them together afterwards with other tools. but shouldn’t a professional program like sony vegas cater to all needs?

I don’t believe that what you’re asking for is a professional feature. While you’re pointing at Vegas, what you’re asking for can’t be done in Xpri, Vegas, Premiere, any Avid product, Canopus, Final Cut, Speed Razor, AIST, or any other “professional” product.
The delivery you’re looking for doesn’t serve the general public, nor is there any broadcaster in the world that uses such a delivery mechanism.
No NLE wants to be a party to piracy, and the process you’re describing is predominantly a pirate’s process (not suggesting that’s what you’re doing, simply pointing out that it’s common for pirates to use these methods).
In short…no. I don’t believe a professional tool should cater to non-professional, non-common uses or codecs. Another example might be….REAL Networks specifically prohibits the ripping of their REAL streams. No NLE can/will do it. But there are many tools out there that can. But I can think of a lot of professional uses for ripping REAL streams from the web.
Anyway, GordianKnot, AVISynth, and a few other tools can do this, but you’re apparently already of them.Douglas Spotted Eagle
