[Best For] Highly recommended for: character or style consistency from stills, product look references, multi-image subject guidance, and prompt-driven scenes featuring a referenced subject. [Limitations] Do NOT use this model for first or last frame transitions, when the primary input is a reference video, or if you need 2K or a 4 second clip. prompt, duration, resolution, and reference_images are required. Do NOT send first_frame_image, last_frame_image, or reference_videos on this endpoint. [Routing] Choose MiniMax H3 Max I2V when the user provides reference stills.

[Core Function] MiniMax H3 Max 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 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.

[Best For] Highly recommended for: prompt-only storyboards, character-driven shorts, cinematic B-roll from text, and drafts without image inputs. [Limitations] Do NOT use this model if you need to condition on images, first or last frames, or reference videos, or if you need 2K or a 4 second clip. prompt, duration, resolution, and ratio are required; ratio must be one of the documented aspect ratios. [Routing] Choose MiniMax H3 Max T2V for text-only MiniMax H3 Max video. If the user provides a start or end frame, use MiniMax H3 Max FL2V. If they provide reference images, use MiniMax H3 Max I2V.
