How I Fixed Avid Media Composer Speech-to-Text, PhraseFind & "Database Offline" Errors on macOS Tahoe
For nearly a week, I found myself doing something every filmmaker dreads: troubleshooting software instead of editing a documentary.
I rely on Avid Media Composer every day, and one of the biggest reasons I upgraded to Media Composer Ultimate was to take advantage of Speech-to-Text, ScriptSync, and PhraseFind AI. Instead, every attempt to transcribe footage failed immediately.
After countless hours searching forums, reinstalling software, updating Media Composer, checking licenses, signing in and out of Avid Link, and trying every suggestion I could find online, nothing worked.
I decided to write this article in the hope that it saves another editor from losing an entire week to the same problem.
My System
Mac Studio (Apple Silicon)
macOS Tahoe 26.5.2
Avid Media Composer Ultimate 2025.12
The Symptoms
If you're experiencing one or more of these issues, this solution may help:
Speech-to-Text fails immediately
Transcribe produces an error
PhraseFind AI doesn't work
ScriptSync won't generate transcripts
Transcript Tool shows Database Offline
Manage Transcript shows Database Offline
The Find window displays a red status indicator
In my case, transcription simply would not start.
A Common Misunderstanding
During troubleshooting, I was told by one member of Avid Technical Support that macOS Tahoe 26.5.2 was not supported by Avid Media Composer 2025.12 and was advised to downgrade my Mac back to macOS Sequoia.
Based on my experience, that turned out not to be the cause of my issue.
After following a different troubleshooting procedure, Media Composer worked normally on the same Mac running the same version of macOS. That suggests the underlying problem was related to Media Composer's search and indexing components rather than the operating system itself.
Every system is different, so your experience may vary, but before spending hours downgrading macOS, it's worth trying the reset procedure below.
The Solution That Finally Worked
These are the steps that resolved the issue on my Mac.
1. Uninstall Avid Media Composer
Completely uninstall Media Composer.
2. Restart Your Mac
Do a full restart before continuing.
3. Remove the Search Folders
Create a backup folder on your Desktop.
Move (do not permanently delete) these folders into the backup folder if they exist:
/Users/Shared/AvidMediaComposer/Searchand
/Applications/Avid Media Composer/SearchMoving them allows Media Composer to create fresh search and indexing databases during installation.
4. Restart Your Mac Again
Another restart helps ensure no background services are still running.
5. Reinstall Avid Media Composer
Install your version of Media Composer again.
6. Restart One Final Time
After installation finishes, restart your Mac.
7. Launch Media Composer
Open your project and test:
Speech-to-Text
ScriptSync
PhraseFind AI
In my case, everything immediately started working again.
What I Learned
This experience reminded me that software problems aren't always caused by the operating system. Search databases, indexing services, or corrupted application components can sometimes create symptoms that appear much larger than they really are.
Before making major changes like reinstalling macOS, it can be worth trying a clean reset of Media Composer's search system first.
Hopefully This Saves You Some Time
As documentary filmmakers, editors, and storytellers, our time is far better spent crafting stories than troubleshooting software.
If this article saves even one editor from spending a week chasing the wrong solution, then it was worth writing.
If this fix worked for you—or if you discovered another solution—I'd love to hear about your experience. Sharing our knowledge makes the editing community stronger.
Happy editing!
