There was no “kick off” meeting with some people to decide “now we’ll start writing a video editing software”. Rather, the initiators of the project were all suffering from some well-known problems when using the Cinelerra video editor…
Development methods and coding standards
The Clean Code movement evolves around a set of principles and practices to guide a professional attitude for software developers. The original pages with extensive explanations are unfortunately written in German.
→ we provide a condensed outline of the principles in English…
Since 2025, Lumiera uses the Git-flow branching pattern to organise the integration of coding developments and to prepare releases and provide bugfixes.

Principles and reasoning are described in this Background Article

Actual conventions and usage patterns can be found in the Technical Docu
Research Topics
As part of our development work, we sometimes have to conduct studies and research on sophisticated technologies or complicated methods, because sometimes it is not obvious how best to handle a topic.
- Video Output

-
In 2025 we looked into the currently well established technologies for outputting raw video frames from a desktop application.
