Get Paperwolf Studio
Download the macOS app from the Studio app page. Open the DMG, drag Paperwolf Studio into Applications and open it from there.
Try it, or activate your licence
Without a licence, every plugin runs as a free trial: every feature, with a watermark, for as long as you like. After purchase you receive a licence key. Paste it into the app’s Account section: the app activates this Mac and saves the licence, and the watermark disappears.
Quit Resolve, then install
Quit DaVinci Resolve completely. In the app’s Library, choose Install for a plugin or Install all. macOS asks for administrator approval. The app waits while Resolve is running.
Find the effects
Reopen Resolve → Effects → OpenFX → Paperwolf Studio. Add an effect to a clip on Edit/Cut, or a node on Color/Fusion, then choose a look.
