Dolby Atmos - 3. Export

Dolby Atmos - 3. Export



MIST allows you to export a Dolby Atmos file in two different ways, depending on your needs.

  1. The EXPORT function from the Media bin
  2. The MASTER DELIVERY module


Export from the Master Delivery module


When using the Master Delivery module, the entire Composition on the timeline is taken into account for exporting the file: frame rate, color space, Time Code, Composition length, etc.
This is also the way to export a file that has been edited.

Accessing the Master Delivery module

After having saved your composition (CTRL + S), click on DELIVER on the bottom menu of the timeline:

Accessing the Master Delivery Module


Export a standalone Dolby Atmos BWF ADM file from the Master Delivery


-> To export just the audio in stand alone, you need to select the format DOLBY ATMOS MASTER:





GENERAL Tab

-> Set the name of the output file

-> Set the desired start time code for the output file


IMMERSIVE AUDIO Tab

->   Set the FFOA OFFSET (different from the effective FFOA TimeCode if the Start TC is not 00:00:00:00 in the source file).
   
By default MIST displays automatically the Immersive Audio tracks present in the timeline. 

To manage the number of tracks to be exported, use the DELETE icon to delete one specific track, or the REFRESH icon at the bottom of the page.

-> If there is multiple tracks on the timeline, expand the track to display the Mapping, and click on the drop down menu to select the track to export:





OUTPUT 

-> Select the output destination.       
     Click on the DISK icon at the end of the Destination path field.

-> Start the export with the button MAKE

Export a standalone Dolby Atmos IAB file from the Master Delivery

-> Select Elementary Stream Master.


This format allows to export separate streams of video and audio from the composition on the timeline.

-> Click on the CONTAINER Drop Down menu to select the FORMAT  for exporting the Dolby Atmos file:



-> Select MXF AS-02 IAB  (SMPTE ST 2067-201: Immersive Audio Bitstream Level 0 Plug-in standard).

Export from the media bin


This function allows you to quickly export a standalone Dolby Atmos file, keeping the source file attributes (start time code, metadata, etc.).
If you need to specify encoding parameters, add metadata or assign a specific start time code, you need to use the Master Delivery module.

To export a file from the media bin:

-> Right click on the file from the Media Bin to display the Media Operations and choose EXPORT AS...



-> Browse the directories to select the file output location

-> Enter a file name for the output

-> Select the output format:
