DEPRECATED

This OpenTimelineIO adapter is deprecated and not maintained anymore! Kdenlive has native support for OpenTimelineIO since version 25.04. This native integration offers more features and works much more reliable than the adapter does. See our documentation for details.

OpenTimelineIO Kdenlive Adapter

This repository contains the OpenTimelineIO adapter for the Kdenlive file format (*.kdenlive). It is distributed under the MIT License.

What is Kdenlive?

Kdenlive is a Free and Open Source video editing application, based on MLT Framework and KDE Frameworks.

In case you are looking for the source code of Kdenlive, it is here: https://invent.kde.org/multimedia/kdenlive

What is OpenTimelineIO?

OpenTimelineIO is an interchange format and API for editorial cut information. OTIO contains information about the order and length of cuts and references to external media. It is not however, a container format for media.

For integration with applications, the core OTIO library is implemented in C++ the project also supports an official python binding. The python binding includes a plugin system which supports a number of different types of plugins, most notably adapters (like this one).

Adapter Plugins

To provide interoperability with other file formats or applications lacking a native integration, the opentimelineio community has built a number of python adapter plugins. Beside Kdenlive this includes Final Cut Pro XML, AAF, CMX 3600 EDL, and more.

For more information about this, including supported formats, see: https://opentimelineio.readthedocs.io/en/latest/tutorials/adapters.html

A list of tools and projects using OpenTimelineIO can be found here.

Installing

As a user you can usually just install the adapter through the Kdenlive user interface or directly from pypi.org with this command

python -m pip install otio-kdenlive-adapter

Development

The OpenTimelineIO documentation can be found here: https://opentimelineio.readthedocs.io

Testing the plugin during development

# In the root folder of the repo
pip install -e .

# Test an adapter for instance
otioconvert -i some_timeline.otio -o some_timeline.kdenlive

Unit tests

It's always a good idea to write unit tests for you code. Please provide tests that run against supported versions of python and OpenTimelineIO.

To run the unit tests do

# In the root folder of the repo
pytest

Before pushing changes you should also run the linter

flake8 --show-source
