Create and Transfer Editing Proxies for Avid Media Composer with Silverstack Lab

This article covers features which are only available in Silverstack Lab.

Create Editing Proxies in Silverstack Lab

Silverstack Lab allows to create DNxHD and DNxHR MXF clips (OP-Atom) that are optimized for editing in Avid Media Composer. Take a look at the article Transcoding in Silverstack Lab to learn more about transcoding in Silverstack Lab.

Creating AAF files

By enabling the checkbox in the transcoding configuration settings you can additionally create AAF files that enable an easier ingest workflow for Media Composer:

Setting the Tape Name for Matching MXF and ALE

In order to make the matching of metadata from the ALE (Avid Log Exchange) file work, it is necessary to embed according metadata into the transcoded MXF clips.

In Silverstack Lab this is done via the Metadata Export option of a transcoding configuration. Configuring the Avid Media Composer metadata export as intended, not only makes sure that the ALE has the correct information to match it to the clips, but also influences the created DNx MXF clips to contain the right information to match the ALE when imported in Media Composer.

To set this up first select the transcoding configuration in the right bar and in the settings section scroll down to the “Metadata Export” section:

Click the “Configure…” button to control the settings for the ALE export and the MXF:

In the “Match clips based on…” section you can choose the matching criteria that will influence both, the MXF and the ALE, to fit together.

When you export an ALE afterwards from the re-ingested transcoded bin manually, make sure to choose the same export settings in order to match it to the created MXF files.

Transfer Editing Proxies to Avid Media Composer

To transfer editing Proxies to Avid Media Composer you have to move the created MXFs into a certain folder on an external volume to be detected:

/Volumes/[YourVolume]/Avid MediaFiles/MXF/

In this directory you have to create numbered folders the MXF clips have to go into, so e.g.:

  • /Volumes/[YourVolume]/Avid MediaFiles/MXF/11
  • or 
  • /Volumes/[YourVolume]/Avid MediaFiles/MXF/12

Going forward there are multiple ways of ingesting the created proxy clips into Media Composer. You can either:

  • 1. Drag & drop the created AAFs into a Media Composer Bin
  • 2. Have Media Composer create an .mdb file in the MXF structure and drag & drop it into a Media Composer bin:
    • 1. Open Avid Media Composer (AMC) and your project to have Media Composer detect the media
    • 2. Go back to the ../MXF/11 folder in Finder and drag & drop “msmMMOB.mdb” into a bin in AMC
