How can we help?

No. Since Resolve 19.1, Blackmagic only lets scripts open their own window in DaVinci Resolve Studio. Every Krispy Tools script has a window, so you need Studio 19.1 or newer.

If you are not sure which version you have, open DaVinci Resolve > About DaVinci Resolve. Studio says "Studio" in the title.

Unzip the download. Copy the .lua file (and any folder that came with it) into Resolve's Utility scripts folder:

Windows: %APPDATA%\Blackmagic Design\DaVinci Resolve\Support\Fusion\Scripts\Utility

macOS: ~/Library/Application Support/Blackmagic Design/DaVinci Resolve/Fusion/Scripts/Utility

Restart Resolve, open a project, then choose Workspace > Scripts and click the tool's name.

Restart Resolve after copying the file; the Scripts menu only refreshes on start.

Check that the .lua file sits directly in the Utility folder (or one folder inside it), not inside the ZIP or a Downloads folder.

On macOS, use the folder inside your user Library (~/Library), not /Library. In Finder press Cmd+Shift+G and paste the path.

Most often this is the free version of Resolve, which blocks script windows. Check that you run Studio 19.1 or newer.

Open Workspace > Console in Resolve and run the tool again. If you see a red error line, copy it into your support email; it tells us exactly what failed.

Make sure a project and a timeline are open before you start the tool.

Yes, on all computers you personally use, for example an edit suite and a laptop, on Windows and macOS. Studios with several editors should buy one copy per editor.

Yes. If a tool does not work for you within 14 days of purchase, email us with your order email and we refund it in full. We may ask one or two questions first, because many problems are a quick fix.

Fixes and improvements to the version you bought are free and appear in My purchases. We will email you when an update matters.

Yes. The tools are Lua scripts that run inside Resolve, so the same file works on Windows, Intel Macs and Apple Silicon. Video Difference Marker also uses FFmpeg; its page explains the one-time setup.

Windows: install FFmpeg once with: winget install Gyan.FFmpeg

macOS: install Homebrew, then run: brew install ffmpeg

Restart Resolve afterwards so the tool can find the new programs.

SRT Replacer matches by time. Use an SRT that was exported from the same edit (for example with Subtitle Creator), and run Dry Run first to see the match count.

If your timeline does not start at 01:00:00:00 or 00:00:00:00, the tool detects the offset; check the mode it reports in the log.

Most changes can be undone with Ctrl+Z / Cmd+Z in Resolve. For big batch jobs, save a copy of the project first; the tools always show a preview or dry run before they change anything.
