# 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.

+ Omit blank MiniMax resolution and duration overrides from the request. Report

+ invalid duration strings with a `ValueError` naming `MINIMAX_VIDEO_DURATION`

+ before submission. The provider checks model-specific resolution and duration

+ combinations. Clear both override variables in offline video test fixtures.
