Lumiera -- Significant Changes
|
|
==============================
|
|
Version: 0.pre.04~rc.1
|
|
:Date: 11/2025
|
|
|
|
*************************************************************
|
|
Lumiera is a non-linear video editing and compositing tool.
|
|
|
|
NOTE: as of 11/2025, Lumiera is in early development stage;
|
|
it is not usable yet. This is a preview Release of a
|
|
current development snapshot in pre-alpha stage.
|
|
|
|
Source code and a list of all contributors can be retrieved
|
|
from `git://git.lumiera.org/LUMIERA`
|
|
*************************************************************
|
|
|
|
|
|
|
|
In the current stage of development, the focus is primarily on the
|
|
overall integration of fundamental functionality at all levels of
|
|
the code base.

Lumiera pre-Alpha Versions
|
|
--------------------------
|
|
|
|
As of _11/2025_ (0.pre.04)::
|
|
This version is again motivated by a series of major upgrades and clean-up.
|
|
Compilation now requires C++23 and Debian/Trixie is considered the reference
|
|
platform. The GUI is connected to the core over an asynchronous messaging
|
|
bus and the timeline display has been reshaped to accommodate flexibly
|
|
nested structures of media content, instructed by the session through
|
|
a series of _diff messages_. A scheduler has been implemented to drive
|
|
the Render Engine, but the connection to the player and UI for output
|
|
is yet unfinished.
|
|
|
|
As of _11/2015_ (0.pre.03)::
|
|
A lot of long standing maintenance work has been done.
|
|
The Project upgraded to C++14 and Debian/Jessie as reference platform,
|
|
followed by clean-up of workarounds now obsoleted. On the GUI side, we largely
|
|
made the transition to GTK-3, which leads to a rework of our timeline widget,
|
|
which is in progress but not finished yet. This work also spurred an effort
|
|
to reorder the connection and communication between core and the UI, which
|
|
is expected to be asynchronous. Due to the limited developer resources,
|
|
work on the Engine and Player part is stalled.
|
|
|
|
As of _10/2013_ (0.pre.02)::
|
|
The data models have been elaborated and some significant parts of the session
|
|
are finished. Work has continued with time handling, a draft of the output
|
|
connection framework, a draft of the player subsystem and interfaces to the
|
|
engine and processing network. Unfortunately there was a considerable slowdown
|
|
and decrease in team size, yet still the code base is growing towards 90k LOC.
|
|
No tangible progress regarding the GUI and the backend.
|
|
|
|
As of _1/2011_ (0.pre.01)::
|
|
The project has created and documented a fairly consistent design,
|
|
and some parts implemented -- progressing from the technical foundations.
|
|
The code base is approaching 65k LOC. Roughly half of this is test code.
|
|
The Application can be installed and started to bring up a GTK GUI framework,
|
|
but the GUI is rather preliminary and not connected to core functionality.
|
|
The video processing pipeline exists only in the blueprints.
|
|
|
|
As of _2/2008_::
|
|
The project has been separated completely from Cinelerra, the parent project.
|
|
The Community, which at that time was largely identical to the Cinelerra-CV community,
|
|
choose the new project name **Lumiera** through a collaborative selection and vote.
|
|
The basic project infrastructure was established, and work on the new codebase
|
|
was underway. It is clear that no results other than a test suite can be shown
|
|
in the foreseeable future.
|
|
|
|
As of _7/2007_::
|
|
A group of volunteers has formed to address some longstanding issues and limitations
|
|
of **Cinelerra**, which we all used for video editing tasks requiring professional quality.
|
|
The plan was to restructure some central parts of the render engine: introduce a Builder
|
|
for render pipelines and use Placements to control arrangement of clips and a unified
|
|
Data-Backend to coordinate usage of system resources. These innovations would serve
|
|
as anchor, with the intention to propose the reworked codebase as a new version
|
|
of Cinelerra, in the hope of turning Cinelerra development into a more
|
|
participatory process going forward.
