Dolby Vision Trims License Not Loading in DaVinci Resolve

Estimated reading time: 2 minutes

 

Summary

 

If your Dolby Vision Trims license fails to load in DaVinci Resolve, you'll receive an error message and lose access to the Trim controls in the Dolby Vision tab. This article walks through the most common causes and how to resolve them.

 

 

Who this is for

 

Colorists and post-production professionals using DaVinci Resolve with a Dolby Vision Trims license.

 

Symptoms

• An error message appears when attempting to load the Dolby Vision Trims license
• The Trim controls in the Dolby Vision tab are unavailable

Checks

Before attempting a manual fix, verify the following:

• The license file is unzipped — you should be accessing the file named Dolby_Vision_CMU_License.bin, not a compressed archive
• You have the required access rights to the license file
• The license file hasn't been corrupted during copying or transfer
• Your system username contains no special characters (e.g., accents or symbols) — this applies to both local accounts and Active Directory accounts

License file locations

DaVinci Resolve stores the Dolby Vision license in the following directories:

Windows

C:\Users\UserName\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support\DolbyVision

macOS — before Resolve v18.6.6

Macintosh HD/Library/Application Support/Blackmagic Design/DaVinci Resolve/DolbyVision

macOS — Resolve v18.6.6 and later

/Users/username/Library/Application Support/Blackmagic Design/DaVinci Resolve/DolbyVision

 

Resolution

If the license still won't load after completing the checks above:

1. Manually copy the license file to the appropriate directory for your OS (see above)
2. Rename the file to license.bin
3. Relaunch DaVinci Resolve and attempt to load the license again

Notes

> Important: Don't use special characters in your system username. Resolve won't be able to access the license if your username contains accents or other special characters.

> Note (macOS): The user Library folder (~/Library) is hidden by default. To access it, hold the Option key and select Finder > Go > Library.
