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:

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)>

Solution: Run this command in the terminal (replace the Python directory with wherever Python is installed on your computer).
