Must be a new trend created by the "Logan" ingests:

Now, just one drive for all content formats being: 2D 3D and ATMOS

ATMOS sound files are now VF files with it's own key that gets attached to the 2D and 3D content.

Keys arrived also today.

It's the general transition to SMPTE DCPs. Before, Interop was the industry 'standard', but ATMOS DCPs had to be SMPTE DCPs, and thus were distributed on dedicated SMPTE-only disks. Now it appears safe to distribute general non-ATMOS DCPs in SMPTE as well, so all versions can be on a single disc and in a single Composition Package. All ATMOS data/assets are additional aux data, so plain 5.1/7.1 CPLs and ATMOS CPLs can coexist together with their media in the form of OVs and VFs.

However, that ATMOS aux data may be ingested even on non-ATMOS equipped systems, eating disc space. So make sure to deselect the ATMOS VF if you don't have ATMOS.

Thx for the info.
Makes more sense now.

I've noticed, as least with our servers, that we have no issues with SMPTE content - even the content made using the DCP-O-Matic software and with the SMPTE encoding.
