Model and format selection
Honor an existing model choice. Otherwise prefer MiniMax H3 when available, and inspect the running backend for partitions, reference modes, audio, resolutions, duration limits, and long-video options. Do not assume hosted and local services have identical limits, quality, prices, or parameter names.
If another model is requested, use its real documented input contract. A provider switch needs the user's authorization; never silently use a different service because a preset names it as a fallback. For an authorized mixed-model workflow, record model and settings per shot and check cross-shot style differences.
Keep delivery resolution separate from native generation resolution. Record actual width/height, fps, frame count, and any crop, retiming, or upscaling. Do not claim native 2K when the video was generated at 768p and restored later.
Compile shot action, camera, identity, scene, and audio into the chosen model's prompt format. For H3 use the bundled writing guides. Strip production labels and preview grids. Prompt for designed silhouettes, elastic action, material and lighting details when these belong to the user's 3D style; do not add text/UI just because a model can generate them.
