Dolby Atmos Mix Re-Rendering to 5.1, 2.1 etc.

Hey Everyone!

I’m currently trying out Davinci Resolves new Dolby Atmos features and I’m very happy! I mixed something crudely together in 7.1.2 just for testing purposes, and now I can’t seem to find a way for re-rendering this existing mix to 5.1 Dolby Atmos, or just normal 5.1 for that matter.

I got the impression that were possible and it was one of the advantages of using Atmos. I read that the atmos production suite in pro tools had that option and since full documentation isn’t out yet, I’d like to ask wether you guys know of that option in Davinci 17/Fairlight.

I thank you all very much!

Offline re-renders are not currently possible with the native Renderer.

However, Resolve's monitoring panel exposes various downmix configurations (including 5.1 and 2.0) which audition the Renderer directly.

Binaural Settings may be configured via the Track Index and
Fairlight menu > Immersive Audio > Renderer Settings.

Thank you so much for your answer! I will take a look at all you just wrote and maybe come back to ask a follow up question if I don’t understand things still. Thanks again

I'm quite sorry that I still have some questions

I've attached a picture down below. Is this the monitoring panel you mentioned? I've changed it from 7.1.2 to 2.0 and tried both exporting a master file as well as exporting audio from the deliver page, which both failed in changing the original results. :/

Maybe you could guide me a bit further? My ultimate goal is to export this 7.1.2 Dolby Atmos as a 5.1 standard that I can listen to on our AVR Setup at home.

As mentioned, the native Renderer does not currently support offline re-renderers, but one can audition the Renderer directly which forms the basis of re-renders.

Is this an audio-only workflow?

AV Receivers often require a video component such as an .mp4 file with Atmos encoded as Dolby Digital Plus and h.264 encoded video.

Dolby provides tools for this purpose:

Alternatively, AWS Elemental MediaConvert provides workflows to create compliant media for auditioning mixes on consumer equipment.

I did not try to re render an already exported master file, but tried to export the original mix, made in resolve (which is 7.1.2) as 5.1. Is the picture I attached the panel you spoke of used to "audition" the Renderer directly? As I understood it "auditioning" the Renderer would allow me to export a 5.1 or 2.0 file.

I overlayed some simple video footage for testing purposes.

Thanks for this! I will take a look at it.
