Light Version

Note

Audio transcription has been removed on this version. This means less setup, but a subtitles (SRT) file is required as input. Use this if you already have a way of transcribing video (such as Davinci Resolve Studio's built-in subtitles feature, or CapCut subtitles) and you just want subtitles with a custom theme.

Creates themed subtitles from an SRT file.

Step 1

Install any version of Python (tick "Add python.exe to PATH" during installation)

Step 2

Download auto-subs-light.py and place it in the Utility folder of the Fusion Scripts folder.

FAQ

1. Auto-Subs not opening

Verify that Resolve detects your Python installation by opening the Console from the top menu/toolbar in Resolve and clicking py3 at the top of the console. Ensure that Path in your system environment variables contains the following:

C:\Users\<your-user-name>\AppData\Local\Programs\Python\Python312
C:\Users\<your-user-name>\AppData\Local\Programs\Python\Python312\Scripts\

Use Everything to quickly search your computer for it (Windows only).

3. MacOS Error

<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1006)>
