Creating with Hailuo 3.0

Hailuo 3.0 is a third-party video generation model from MiniMax, available on Runway. It excels at multi-reference workflows — for example, you can replace a character in a reference video with a subject from an image while preserving the original camera motion, or pace a generation to match an audio reference.

This article covers how to access Hailuo 3.0 in Custom mode, prompt and input best practices, available settings, and what to expect from your generations.

Spec Information

Step 1 – Selecting Hailuo 3.0

The model picker lives at the bottom of the generation panel. Hailuo 3.0 is available in Custom and Workflows on paid plans.

1. From the left sidebar, click Custom.
2. Select the Video tab at the top of the generation panel.
3. Click the model dropdown at the bottom of the panel and type in the search bar Hailuo 3.0.

Step 2 – Writing the prompt

Your prompt will vary depending on your inputs and what you're trying to accomplish. In any creation mode or model, we recommend using positive, unambiguous, and outcome-focused language. Hailuo 3.0 handles complex, multi-part prompts well, so you can include multiple details — subject, action, setting, camera movement, and style — in a single prompt.

Using the reference inputs

Write your prompt as if you're describing the scene you want to appear, as well as how each input should be used.

• Keyframes — add a first frame, or both a first and last frame, to guide the start and end of your generation; your output's aspect ratio will automatically match your keyframe image
• Image references — add up to 9 images to guide the subject, style, or composition, especially useful for bringing a specific character or object into your generation
• Video references — add up to 3 videos to guide motion, camera movement, or scene structure; combine with image references to replace a character in the reference video while preserving the original camera motion
• Audio references — add up to 3 audio files to influence the pacing and rhythm of your generation

Note: Keyframes cannot be combined with reference inputs.

Tip: Hailuo 3.0 shines when multiple reference types work together. Try pairing an image reference for your subject, a video reference for camera motion, and an audio reference for pacing in a single generation.

Step 3 – Generating with Hailuo 3.0

Before generating, review your settings:

• Prompt — describe the video you want to generate, including how each reference should be used
• Inputs — confirm your keyframes or references meet the requirements in the Spec Information table, and remember that keyframes and references cannot be combined
• Aspect ratio — choose from 16:9, 4:3, 1:1, 3:4, 9:16, or 21:9; when using keyframes, the aspect ratio is set automatically to match your keyframe image
• Duration — set between 5 and 15 seconds; the default is 5 seconds

Credit cost is driven by your duration selection at 15 credits per second, plus 2 credits per image reference and 13 credits per second of any reference video you attach. Audio references do not add to the cost. See the Spec Information table for the full breakdown.

Note: Some combinations of inputs are not allowed. If a selection is unavailable, adjust your inputs or resolution and try again.

Once your prompt and settings are ready, select Generate.

Next steps

Once you've generated with Hailuo 3.0, keep working with your output:

• Edit Studio — Edit your generation without starting over: swap subjects, adjust lighting, or restyle the shot with Aleph 2.0 while keeping the motion you liked.
• Upscale Video — Bring your 2K output up to 4K for final delivery.
