DCP and Dolby Vision + ATMOS

[Dag]

Hi, how can I create a DCP with Dolby Vision and Dolby Atmos data?
I have a deliverable IMF with both video and audio files.
Choosing folder for import it want work, choosing file and load the CPL xml I got a lot of errors.
Choosing the MXF files it self load it in but I do not see the Dolby Vision/Atmos metadata so I can verify if it comes with it and would be recognized on playback.

Best,
Dag

Currently, Theatrical Vision only can play at about 250 DOLBY CINEMA Worldwide

Colour is FULL (Not ZYZ). and different metadata than IMB
To QC/Colour, you NEED a PROJECTOR DCI with CUSTOM Dolby Vision Integrated Media

ATMOS
=====

The IMF Atmos audio is specked to be created with a BROADCAST tool/editor.
But the Atmos master is NOT listened in "Theatre Layout"

Atmos at Theaters has significant differences playing respect a broadcast Atmos
- Uses until 64 Schannels rendering
- Bass management specific for surround channels
Different listening curve....

So, instead that it's possible convert from a IAB or even mobile phone to DCP Atmos, is not a good idea because you don't know what is listening later
The current approach is move with your Atmos/IAB master to a CERTIFIED Theatrical Atmos Studio and in few hours modulate your mix, objects, LFE and surround subs to appropiayte level and correct eq curve. Create the MXF Atmos, and deliver to DCP Authoring this MXF

I hope DCP-o-Matic can implement easy. Need Package as:
- From SMPTE MXF PCM Audio Track with 7.1 and *ALMOST* 14 channels (silent audio in unused)
- erase channel 14 and create Atmos Timecode with public ASDCP library
- Include the Atmos MXF delivered from studio ias AUX data in Package

Regards,

Jaume

Hi Jaume,
i have question about ATMOS
If i have a DCP SMPTE with Atmos track i can simply replace 5.1 sound to local dubbed?
No need recreate Atmos MXF?
Yes, i know to need create 14 tack with sync

Hi Igit,

(Sorry for large delay to reply)

The Audio of a Dolby Atmos CPL is really THE SAME AUDIO CONTENT but mixed with different path/chain.
So, if you replace the audio with another language, you must replace also the ATMOS track with a new with te new language version.
Failure to do,, the ATMOS-enabled cinema plays the original version and NON-ATMOS cinema the dubbed version!

To create a new WAV localised, you need the M+E (Music/Effects) + new dubbed voices and mix to new wav
Same procedure for ATMOS Track, using M+E Atmos. Dubbed voices can be the same.
A Best procedure is made the ATMOS MIX & TRACK 1st and "render" the wav 5.1 and/or 7.1 files from this created ATMOS track automatically...

Finally reopen the DCP and change the PCM and ATMOS and repackage again with PASSTHROW the JP2000 picture. (Decode and Encode loss a lot of quality...)

If is not clear please tell me now and I can elaborate....

Hii Jaume,

I was wondering if you could go more into more detail with differences between theatrical Dolby Vision DCP and standard DCP ?? All I've heard is theatrical Dolby Vision is 108nits and standard is 48 nits.

Thanks

[Jaume(Dolby)]

Correct.

108 N (31FL) in 2D
14FL in 3D!!!
Not XYZ colour but custom color grading...
CUSTOM (Not DCI) DCP

Only can be played in 250 Screens worldwide for Blockbusters
https://www.dolby.com/movies-tv/dolby-cinema/

And colour Grade will be made with two CUSTOM projectors,
currently in one stage in California and other in UK...

CUSTOM (Not DCI) DCP

What about the bitrate ?? Can it be higher the DCI limit of 250mbps ??
