- Add install.py for ComfyUI Manager: tries pip (opencolorio), then conda/mamba, prints manual instructions if both fail - Remove PyOpenColorIO from requirements.txt and pyproject.toml since it is not published to PyPI under that name - Graceful import in __init__.py: logs a clear error and exports empty node mappings instead of crashing ComfyUI when OCIO is missing - Wrap bare PyOpenColorIO imports in nodes.py, ocio_utils.py, and server_routes.py with actionable ImportError messages Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

MP4 (H.264) Standard video via OpenCV — plays in any media player.
|

Animated WebP High-quality lossless/near-lossless, plays in browsers and

most modern viewers. Best for round-tripping back to ComfyUI.
|
||
Animated GIF Universal compatibility; limited to 256 colours.

output_path
|

Full path including filename. The correct extension is appended

automatically if missing (.mp4 / .webp / .gif).

The node passes the IMAGE tensor through unchanged so it can sit inline
