5.1 questions, downmix
on May 21, 2008 at 4:09:46 pm

Two questions about 5.1.

Also, I just need a check of my settings. If given a professionally mastered 5.1 mix with 6 stems, the audio tab tends to default 6 channels of dual mono to -3 db. Is this a correct level setting for 5.1 layoffs? Or should it be 0 db?

I'm sending the mix to an HDCAMSR. Is there a way to have FCP do a downmix of those to a Lt / Rt, if I wanted to do a second layoff pass to add the stereo mix?

I've posted this in the FCP forum as well.

Thanks

Anne

Ann,

I think you are referring to the -3dB for the fold down of the rear surrounds. Compressor does a very good job of folding down a 6 stem 5.1 mix to a stereo LT RT that you can lay off to tape.

Thanks Warren

I'm not sure I see that preset in compressor. The manual is thin on how to accomplish it. I'd appreciate your suggestions.

Ann,

Set up your 5.1 stems in the appropriate channels in compressor. Then go to presets> Formats> Audio> and choose the AIFF setting you need, for example: AIFF 48:24

I'm still unclear about the proper way to output this, should I apply -3 to the mono channels for my FCP output settings?

Thanks very much again
