Our studio just finished doing an Atmos mix for a mobile company client. The MXF is to be sent to dolby for checking and once it's been approved we'll also be doing a DCP for the project, as well as an mp4 with atmos sound to be played using an atmos soundbar. Our dolby contact pointed us to Avid Atmos production suite and the dolby media producer suite, both of which we have already bought.
I just want to know how to go about the workflow here once the MXF has been approved. I assume we then pass it through the dolby media production suite to have Dolby TrueHD or Dolby Digital Plus and then Mux it to mp4.
I would also like to what to use for muxing the audio into mp4. What do you guys use?
Hi Chris, I'm not sure what you mean by testing a consumer Atmos installation. If the audio is not Atmos the AVR will upmix to get all the speakers active but it will not be decoding/rendering Dolby Atmos. If this is what you want to do then yes you can just encode Dolby Digital or Dolby Digital Plus with the Dolby Media Producer Suite but most open source tools will not be able to mux it.
If you have the Atmos Production Suite and Dolby Media Producer Suite you can use our open source muxer that can accept Atmos files. These can be found here:
That would be my recommendation.
Hi adam, I can't seem to find the dolby atmos conversion tool. isn't this part of the avid atmos production suite? thanks
Hi Rayjohn, The Dolby Atmos Conversion Tool is currently part of the Dolby Atmos Mastering Suite. It can be provided separately and will be publicly available in the future to Production Suite Users via this developer site. In the interim I'll email you download links directly. It is probably best to get pricing on the Dolby Media Producer Suite directly from dealers in your region. I've attached a dealer list.
The Dolby Media Producer Suite doesn't ingest .mxf. It only ingests .atmos file sets. For a properly signaled mp4 you could use Dolby Media Generator. You can request an eval copy of this email@example.com.
Hi, Yes when mastering with the Dolby Atmos Production Suite or using the Dolby Atmos Mastering Suite in conjunction with an RMU the master files created are a set of three files: filename.atmos, filename.atmos.metadata, filename.atmos.audio.
The filename.atmos is the input for encoding to Dolby Digital Plus with Atmos Content of Dolby TrueHD when using Dolby Media Producer.
Hello again, I'd like to ask if it's possible to encode the atmos file sets using a different pro tools system other than the one the original project was mixed in. I'm asking because the machine connected to the RMU is osx 10.9, ProTools 12. Which is one version short of what the avid atmos plugin requires (osx 10.10)
The atmos plugin is installed on a protools ultimate 2018, imac high sierra, 7.1 studio config. Is it possible to feed it the mxf and then render the atmos filesets from there?
Hi, Pro Tools does not perform the encoding of the .atmos file set. Dolby Media Producer is used for this.
If you need to get back into Pro Tools from the MXF you'll need to use the Dolby Atmos Conversion Tool to convert from MXF to ADM BWF which can be imported into Pro Tools 12.8 and above which has native Atmos panning. The same conversion tool can be use to derive .atmos from the MXF for encoding. If you are taking the audio back into Pro Tools via ADM BWF import you can remaster using the Atmos Mastering Suite or the Atmos Production Suite to create .atmos. Hope this helps.
Question - can the Dolby Media Producer encode to any 4K video formats? We're attempting to produce 4K Video content with Dolby Atmos audio.
Hi Raheem, Dolby Media Producer encodes audio only. Muxing with video to .ts, .mp4, or fragmented formats requires other applications.
Thank you, AJP. Would it be ok for me to email you some specific questions about this?
Hi! Is it possible to make a video mp4 without an approved .atmos file for testing at a consumer Atmos installation ( lets say a Atmos capable Marantz receiver), with just the Dolby Media Producer Suite v.2, the Dolby Atmos Production Suits, Protools and an open Source muxing tool?
please apologize my bad english, i'm not a native
