+Toucan is a software renderer for OpenTimelineIO files. Toucan can render an
+OpenTimelineIO file with multiple tracks, clips, transitions, and effects
+into an image sequence or movie file.
+
+The project currently consists of:
* C++ library for rendering timelines
* Collection of OpenFX image effect plugins
* Command line renderer
* Interactive viewer
* Example .otio files
+Current limitations:
+* Audio is not yet supported
+* Nested timelines are not yet supported
+* Outputting movie files currently relies on the FFmpeg command line program
+(see below: FFmpeg Encoding)
+
Toucan relies on the following libraries:
* [OpenTimelineIO](https://github.com/PixarAnimationStudios/OpenTimelineIO)
* [OpenFX](https://github.com/AcademySoftwareFoundation/openfx)
