Why and when should I delete media databses?

  • Whenever your media is offline and you are certain your media on the correct file path (root level of hard drive > Avid MediaFiles > MXF > 1)
  • If Media Composer is crashing when you are opening a project. This won’t always fix it but it’s a good place to start
  • Moving media onto Avid ISIS or another type of shared storage solution and the media is offline

Directions:

  1. Close out of Media Composer
  2. Open up Finder (Mac) or Computer (PC) and navigate to your hard drive. Find the Avid MediaFiles folder on the root (top) level. Open it up. Open up the MXF folder. Inside here you’ll see a folder named 1. There may be folders numbered 2, 3, etc. depending on how much media is in the folder.
  3. Inside the 1 folder you’ll find two files: msmMMOB.mdb and msmFMID.pmr. Delete them. Don’t worry, they automatically rebuild when you relaunch Media Composer. See picture below.
  4. Cross your fingers.
  5. Open Media Composer.
  6. Media Composer will re-index the media and doing so recreates the two database files when it boots up before you get to the Select Project window.
  7. Open up your project.
