Lumiera is a Free/Open Source NLE application project for Linux developed by the CinelerraCV community. It was born as a rewrite of the Cinelerra codebase called Cinelerra3 but it is now an independent project with its own name.
Lumiera is still in an early stage of development. It is not usable yet.
Lumiera is being built from the ground up, starting with the engine core. The core is not tied to the GUI but just interacts with it via clearly defined interfaces. Nothing besides brainstorming has been done for the GUI yet. Ideas are collected on a dedicated pipawiki page.
We use a distributed development model backed by the git version control system.
Developers meet monthly on IRC. You can have a look the topics of the next meeting and to the protocols of the past meetings.
As an introduction you can find information on a pipawiki page.
Design documentation can be found in a TiddlyWiki.
You can browse the code repository with webgit.
For the structure of the code look at our Doxygen documentation
Lumiera has not a dedicated Mailing List yet. You can write to the CinelerraCV mailing list.
Join us on the IRC channel #lumiera at Freenode.
