About Hailuo 02

Hailuo 02 is MiniMax's flagship video generation model family, built on a proprietary Noise-aware Compute Redistribution (NCR) architecture that redistributes computational resources according to noise levels in the diffusion process. This innovation delivers 2.5x training and inference efficiency improvements, allowing MiniMax to scale the model to three times as many parameters and train on a dataset four times larger than its predecessor. The result is industry-leading instruction following, realistic physics simulation, and cinematic visual fidelity at a competitive price point. Hailuo 02 supports both text-to-video (T2V) and image-to-video (I2V) inputs, outputs at 768p or native 1080p resolution, and generates clips of 6 or 10 seconds (1080p is limited to 6-second clips).

The Prompt Optimizer Advantage

One of Hailuo's most practical features is its built-in Prompt Optimizer. When enabled, it automatically enriches your input with cinematographic details—camera angles and movement, lighting direction, shadow transitions, color tones, texture, and scene composition. This means creators can write simple, natural-language descriptions and still receive professional-quality output. The optimizer is especially valuable for users who are new to AI video prompting or who want to iterate quickly without manually engineering every detail. For experienced users, disabling the optimizer gives full manual control over the prompt to achieve precise creative intent.

Standard vs. Pro: Choosing the Right Tier

The Standard tier uses fewer credits and is ideal for testing prompts and exploring concepts before committing to a full generation. The Pro tier produces higher visual fidelity and is recommended when cinematic quality matters—product demos, short films, or client deliverables. Both tiers support last-frame conditioning, which lets you supply a target image to control the final frame of the sequence, a feature particularly useful for scene transitions and controlled narrative endings.

Practical Tips for Best Results

• Write like a director: Use present-tense verbs and specify subject motions, camera movements (pan, tilt, zoom, dolly), and emotional beats. Example: "A dancer [slow tracking shot] performs a fluid contemporary routine on a foggy stage, soft blue light, cinematic grain."
• Enable the Prompt Optimizer for short prompts: For prompts under 50 words, the optimizer consistently improves output quality by filling in cinematographic details you may have omitted.
• Use Standard for iteration, Pro for finals: Start with the Standard tier to nail your composition and timing, then switch to Pro for the final render.
• Leverage last-frame conditioning for continuity: When building multi-shot sequences, use the final frame of one clip as the starting image for the next to maintain visual consistency across scenes.
• Specify art style explicitly for stylized content: For anime, ink-wash, or game-CG outputs, include the style name directly in your prompt (e.g., "anime style", "traditional ink wash painting") to activate the model's stylization capabilities.
• Keep 1080p clips to 6 seconds: Native 1080p generation is limited to 6-second clips; use 768p for 10-second sequences and upscale in post if needed.
