# Video Generation Maintenance

[scripts/generate.py](scripts/generate.py) shares extension-based MIME inference between Gemini references
and MiniMax first-frame data URLs. Reject unmapped suffixes with a `ValueError`
that names the file and supported extensions. Preserve case-insensitive PNG,
JPEG, WebP and GIF metadata without decoding or transcoding images.

Keep provider format acceptance separate from MIME recognition. The public-skill
reference-MIME regressions mock HTTP calls, verify request metadata and exact input
bytes for both providers, and reject unknown extensions before submission.
Preserve the layout of unrelated script code.
