Good news - There are ways to get LUA files working!

How to fix this issue:

LUA files may not work in Resolve due to a few different causes. Below, we’ve listed the most common ones. We recommend going through them in order.

Cause 02: Special Characters In Username

If you use any special characters in your OS username like:

Latin Characters

á, é, í, ó, ú, ý, Á, É, Í, Ó, Ú, Ý

Punctuation

-, -, ., ,, #, @,

Than Snap Captions cannot automatically install itself.

(The reason is there’s a limitation with what LUA files can read)

Solution: Change Username

Change your username to only contain plain characters with the instructions below

Cause 02: (Windows Only) Running DaVinci Resolve in Administrator Mode

If you run Resolve in Administrator Mode, LUA files cannot be accessed through the console.

  • Quit DaVinci Resolve.
  • Reopen it without Administrator Mode.

Solution 02 - Turn off Always Run In Administrator

  2. Right-click the Resolve (.exe) and choose Properties.
  3. Navigate to the Compatibility tab.
  4. UNCHECK the option Run this program as an administrator.
  5. Click Apply, then OK.

Cause 03: Conflicting Applications

Some applications may interfere with LUA plugins in Resolve. Based on user reports, the following programs can cause issues:

  • Discord
  • Notion
  • Spotify

Solution: Close All Other Applications

  1. Close ALL other applications
  2. Force-quit stubborn apps if needed.

    3. You may need to force quit some applications, like spotify doesn’t close when you click the red X 😡).

  3. Ensure ONLY the following are open when installing LUA plugins:
    • DaVinci Resolve
    • Finder (mac) or Explorer (windows)
  4. Restart DaVinci Resolve
  5. Try dragging the LUA file back into the Resolve console

If the plugin loads successfully, the issue is resolved.

Cause 04 - Network Hard Drives

If you have a network hard drive (such as a Synology NAS drive) connected, this can cause issues, even if you’re not actively using it.

Solution:

  1. Disconnect any network hard drives from your computer.
  2. Restart DaVinci Resolve
  3. Try dragging the LUA file back into the Resolve console

If this LUA plugin successfully loads, then your issue is resolved.
