You can use Python hook files to do some custom scripting.

In order to find the hook files the file name must match exactly. Please see list below.
The example scripts can be found here:
https://github.com/das-element/resources/tree/main/scripts/hooks/examples

Script

Description

pre_render.py

Gets executed before each transcoding task

post_render.py

Gets executed after each transcoding task

pre_ingest_load.py

Gets executed before the file paths get loaded into the ingest view

pre_export.py

Gets execture before the library elements get exported

The software follows this order looking for Python Hook files.

  1. directory defined in the $DASELEMENT_RESOURCE/scripts/hooks environment variable

  2. your local .das-element folder (for Linux: ~/.das-element/scripts/hooks or for Windows %homepath%/.das-element/scripts/hooks)

Pre Render Hook

The input is the resolver data dictionary which will be used to resolve the path pattern. You can modify it here before the transcoding task gets processed.

You will need to return the same dictionary with your changes included.

In the example below, in order to resolve a path pattern like <custom.dependecy> you need to add some value for the custom data. If that is not provided the resolve would otherwise fail if you re-render the proxies and there is no main task to provide the dependency which we normally would get from the post render hook after sending the task to the render farm.

Post Render Hook

The input is the output of the process called by the custom command task.

You will have to return a Dictionary which will be added as custom to the resolver data and can later be accessed in the Path Builder. return {'dependency': job_id} can later be resolved with <custom.dependency>

Pre Ingest Load

This hook can be used to parse the file paths to set tags and the category from the file path before the items are loaded into the ingest list. These tags and the category will automatically populate the ingest list items.

The input is a List of Dictionaries and the same has to be returned from the function.

Pre Export

This hook can be used to edit, reformat or add additional values to the export from the library elements.

Tip: use this hook to create a CSV file that you can import into Shotgrid

The input is a List of Dictionaries and the same has to be returned from the function.
