DV-2 AVI with audio into Encore?

[sky captain]

I'm using Encore 2.0 to author a feature film that's 2 hours, 20 minutes in length.

Usually, I would bring in a DV-1 AVI (no audio) and WAV file separately and transcode them in Encore.

However, my editor mistakenly gave me a DV-2 AVI with the audio interleaved.

I brought that file in to see if it would work in the authoring stage. So far, so good.

When I go to transcode, will it play nice? Will it make a silent MPEG-2 and a separate AC3 file? I'm concerned because I know that you're not supposed to make MPEG-2 files with audio -- I just want to make sure that doesn't happen.

I don't think you'll have any problems, but if you're concerned, you could just convert the original DV file back to type 1. DVdate should do it.

Haven't used that program, but I was considering doing another render or conversion.

The reason I hesitate is that the resulting file is over 30 gigs and takes several hours to render.

It should be irrelevant.

A Type 1 and Type 2 DV AVI both contain the original DV which, itself, contains audio and video. A Type 2 DV AVI simply has an extra copy of the audio for older software that can't understand Type 1.

As far as Encore is concerned, both types should appear the same as far as content goes.

As I understand it, you can do uncompressed audio with DV-2, but DV-1 requires DV compressed audio.

Is that right? Certainly, with VT Edit, I seem to be limited that way for audio output.

That doesn't sound right (no pun intended!)

DV uses PCM audio (just like a standard WAV file). Typically, it is 16-bit at 48kHz but can be 16-bit at 32kHz, 16-bit at 44.1kHz (i.e., just like CD) or 12-bit at 32kHz. The latter is a compressed form and permits two sets of stereo tracks to be recorded.
