}MiniMax H3 FL2V
[Core Function] MiniMax H3 FL2V generates video guided by a first frame, a last frame, or both. [Strengths] It supports first-only, last-only, and first-plus-last conditioning with 4-15 second duration and 768P or 2K output. Output framing follows the input frame imagery. [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. Provide prompt, duration, resolution, and at least one of first_frame_image or last_frame_image. Do NOT send reference_images, reference_videos, or reference_audios on this endpoint. [Routing] Choose MiniMax H3 FL2V when the user supplies a start and/or end frame. For reference images without frame roles, use MiniMax H3 I2V. For reference videos, use MiniMax H3 V2V. For text only, use MiniMax H3 T2V.
