Requirements

Make sure you have OpenTimelineIO (OTIO) installed on your computer before you install the plugin. The easiest way to install OTIO is through pip.

pip install opentimelineio

You may also install OpenTimelineIO by using the python version which ships with Hiero|NukeStudio. Replace the python version in the example below with the one you find in the applications root folder.

# Example using python 3 shipped with Nuke13+
python3 -m pip install opentimelineio

If you installed OTIO in another way, please make sure you have OTIO's python package available in the PYTHONPATH environment variable.

Plugin Installation

The easiest way to install the plugin is to unpack the contents to the .nuke folder in your "HOME" directory.
For Hiero/Nuke Studio version < 12 extract to the .hiero folder.

~/.nuke/Python/Startup/otioexporter
~/.nuke/Python/StartupUI/otioimporter

If you choose to install the plugin to another location, make sure to append the full path of the folder containing the Python folder to the HIERO_PLUGIN_PATH environment variable.

export HIERO_PLUGIN_PATH=/my/shared/plugin/folder

Usage OTIO Import

Right click in a project bin and select "Import->Import OTIO"

Or you can add tracks to an existing sequence

Usage OTIOExportTask

In Hiero's export dialog choose "Process as Sequence" and create a new preset called "OTIO Export".
Add a new PATH and choose "OTIO Exporter" from the list of available exporters in the CONTENT column.
Make sure to either use the {ext} token or end your filename with an .otio extension.
The "include tags" checkbox toggles inclusion of tags assigned to clips in the OTIO metadata.

You may either export entire sequences or selected items in a sequence.

Known Limitations

• Tags/markers are applied to both clips and track items on import if no metadata indicates source type.
