[Strengths] It supports first-only, last-only, and first-plus-last conditioning with 5-15 second duration and 480P or 768P output. Output framing follows the input frame imagery. Optional prompt_expansion_mode is disabled, balanced (default), or quality. [Best For] Highly recommended for: start-frame animation, end-frame targeting, before-and-after transitions, and storyboard frame bridging. [Limitations] Do NOT use this model for pure text-to-video, reference-image subject remix, or reference-video remix, or if you need 2K or a 4 second clip. Provide prompt, duration, resolution, and at least one of first_frame_image or last_frame_image. Do NOT send ratio, reference_images, reference_videos, or reference_audios on this endpoint. [Routing] Choose MiniMax H3 Max FL2V when the user supplies a start and/or end frame. For reference images without frame roles, use MiniMax H3 Max I2V. For reference videos, use MiniMax H3 Max V2V. For text only, use MiniMax H3 Max T2V. For 2K or 4 second clips, use MiniMax H3 FL2V. ## OpenAPI ````yaml /media-model-api/minimax/minimax-i2v.json post /minimax/minimax-h3-max-fl2v openapi: 3.1.0 info: description: The image-to-video models API from MiniMax. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: MiniMax Image-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The image-to-video models API from MiniMax. security: - bearerAuth: [] paths: /minimax/minimax-h3-max-fl2v: post: summary: MiniMax H3 Max FL2V description: >- [Core Function] MiniMax H3 Max FL2V generates video guided by a first frame, a last frame, or both.
