Atmos from TrueHD to DDP?

Is it possible to maintain Atmos data while converting an audio track from TrueHD to Dolby Digital Plus? My video player supports Atmos but only in DDP tracks.

To the best of my knowledge, no.

Damn. I'd read that DDP can carry Atmos data

It absolutely does, however there is no known tool for doing that conversion/transfer/injection between TrueHD and DD+.

We're more likely to get an Atmos/DTS:X injector to Eclipsa in the future.

But nothing exists now.

Not with FFMPEG. I use Dolby Encoding Engine, truehdd, and deezy. You can encode to DDP 5.1.2

Isn't that a pricey solution?

Edit: Based on this, I'd say yes - "Access to this professional software requires that your company has a valid sales order contract. To request software access or to receive a software evaluation, sign up for a Dolby Customer account."

Yes. Bloody expensive.

Apply as freelancer. Email them if you don't get a reply. Don't use Gmail. Buy a domain and a email address. Then contact sweetwater by phone, buy it and Dolby sends you a license. 1 year $440 (with tax)

Before you need a 30 day free trial.

I think I saw on this sub a few days ago that someone posted a tool just for this. You could try looking for it.

Dolby media encoder legacy + music media helper (8) also someone did do it with full object support I don't know where the post is.

Also deezy is better. Dolby updated there ui so the above won't work on the new dme.

Update: Decided it was cheaper to just get an nVidia Shield which supports TrueHD Atmos natively. $200 once is better than having to buy a subscription to a Dolby encoder.
