Built with open-source software.
RaveCut stands on free, open-source tools made by many people. This page lists every one that comes inside the RaveCut Engine app, the licence each is under, and where to get its source code.
The full text of every licence is in this file. The same file comes in the RaveCut download as Open-source licences.txt, and inside the app: in Premiere, open ≡ in the RaveCut panel and click Open-source licences; in DaVinci Resolve, the same button is under Details in the RaveCut window.
FFmpeg, libsndfile and the other LGPL parts
RaveCut uses FFmpeg to read video and sound. It ships the ffmpeg and ffprobe programs, built by us from the unmodified FFmpeg release under the GNU Lesser General Public License (LGPL) version 2.1 or later, without any GPL or non-free parts. The exact configure line used is in the full text, along with the source links for FFmpeg, libsndfile, libsoxr and the other LGPL libraries.
Getting the source. Each LGPL part has a link to its exact source release in the table below. For at least three years after you got your copy of RaveCut, you can also ask us for the complete source code of those parts, with our build scripts, for no more than it costs us to send it. Write to support@ravecut.com.
Your rights. You may change and replace those libraries inside the app and use your changed version with RaveCut. RaveCut's terms don't limit any right these licences give you.

This list is made automatically from the app itself each time a new version is built, so it always matches what you download. The RaveCut panel for Premiere Pro contains only RaveCut's own code. The RaveCut window for DaVinci Resolve contains RaveCut's own code and Blackmagic Design's Workflow Integration module from DaVinci Resolve's developer kit, which is Blackmagic Design's software, not open source.
