How It Works

ATR fetches plugins-index.json from this repo to populate the Add-ons → Browse Online section. Users can install plugins with one click.

Plugin Format

Each plugin is a Python .py file exporting:

• PLUGIN_META dict — name, id, version, author, description, category, pipeline_hooks, settings
• filter_frame(frame, frame_index, **kwargs) — per-frame numpy processing
• process(input_path, output_path, **kwargs) — file-level processing (optional)

See the Plugin Development Guide for the full contract, settings schema, pipeline hooks, and examples.
