PUBLIC BETA NOTICE
OpenTimelineIO is currently in Public Beta. That means that it may be missing some essential features and there are large changes planned. During this phase we actively encourage you to provide feedback, requests, comments, and/or contributions.
OpenTimelineIO is an interchange format and API for editorial cut information. OTIO is not a container format for media, rather it contains information about the order and length of cuts and references to external media.
OTIO includes both a file format and an API for manipulating that format. It
also includes a plugin architecture for writing adapters to convert
from/to existing editorial timeline formats. It also implements a dependency-
less library for dealing strictly with time,
You can provide adapters for your video editing tool or pipeline as needed. Each adapter allows for import/export between that proprietary tool and the OpenTimelineIO format.
Documentation, including quick start, architecture, use cases, API docs, and much more, is available on ReadTheDocs
OpenTimelineIO supports, or plans to support, conversion adapters for many existing file formats, such as Final Cut Pro XML, AAF, CMX 3600 EDL, etc.
OTIO also supports several other kinds of plugins, for more information see:
- Media Linkers - Generate media references to local media according to your local conventions.
- HookScripts - Scripts that can run at various points during OTIO execution (ie before the media linker)
- SchemaDefs - Define OTIO schemas.
Installing / Quick-Start
The python-wrapped version of OpenTimelineIO is publicly available via pypy. You can install OpenTimelineIO via:
pip install opentimelineio
For detailed installation instructions and notes on how to run the included viewer program, see: https://opentimelineio.readthedocs.io/en/latest/tutorials/quickstart.html
import opentimelineio as otio timeline = otio.adapters.read_from_file("foo.aaf") for clip in timeline.each_clip(): print(clip.name, clip.duration())
There are more code examples here: https://github.com/PixarAnimationStudios/OpenTimelineIO/tree/master/examples
Also, looking through the unit tests is a great way to see what OTIO can do: https://github.com/PixarAnimationStudios/OpenTimelineIO/tree/master/tests
OTIO includes a viewer program as well (see the quickstart section for instructions on installing it):
If you want to contribute to the project, please see: https://opentimelineio.readthedocs.io/en/latest/tutorials/contributing.html
You can get the latest development version via:
git clone email@example.com:PixarAnimationStudios/OpenTimelineIO.git OpenTimelineIO
You can install development dependencies with
pip install .[dev]
You can also install the PySide2 dependency with
pip install .[view]
Currently the code base is written against python2.7, python3.7 and python3.8, in keeping with the pep8 style. We ask that before developers submit pull request, they:
make test-- to ensure that none of the unit tests were broken
make lint-- to ensure that coding conventions conform to pep8
make coverage-- to detect code which isn't covered
Additionaly, to reproduce CI failures regarding the file manifest, run:
make manifest locally to run the python
C++ Coverage Builds
To enable C++ code coverage reporting via gcov/lcov for builds, set the following environment variables:
When building/installing through
setup.py, these variables must be set
before running the install command (
pip install . for example).
