Fcp2Rpp

A browser-based tool that converts Final Cut Pro and DaVinci Resolve XML timelines to Reaper projects. See the documentation on the tool’s page for instructions and the many caveats.

I use it to convert colleagues’ Premiere Pro and Final Cut Pro XML timeline exports to Reaper so I can work on sound mixing and editing for short film and commercial work.
