SRT Replacer

Swap your captions to another language from an SRT, keeping style and timing.

Choose a translated SRT file. SRT Replacer matches every subtitle to the Text+ clip it belongs to and replaces only the text, with optional line wrapping, so the style, animation and timing stay exactly as they were.

What it does for you

  • A German, Spanish or Japanese version without retyping a caption.
  • Style, animation and timing stay as they are; only the words change.
  • Dry Run shows exactly how many clips will change first.

Requirements

  • DaVinci Resolve Studio 19.1 or newer (the free version of Resolve blocks script windows).
  • Windows 10/11 and macOS 12+ (Apple Silicon and Intel). One file works on both.
  • Install: copy the .lua file into Resolve's Scripts/Utility folder, then open it from Workspace > Scripts.
  • Tested in DaVinci Resolve Studio 21 on Windows 11. The script also runs on macOS (Intel and Apple Silicon). If anything does not work on your Mac, please report it on GitHub or by email.

Important notes

-

If an English SRT sits next to the translated file, it is used to match lines even more reliably.
