MiniMax: Hailuo 02
Hailuo 02 creates video from text or a first-frame image and supports a documented first-and-last-frame workflow. Camera commands, prompt optimization and mode-specific duration and resolution choices help shape the intended shot.
About the model
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Hailuo 02 is MiniMax’s video model for text-driven scenes, image animation and a first-and-last-frame workflow. A written brief describes the subject, action and camera, while supplied frame images can establish the visual starting point or the transition’s destination. Choose the generation mode according to the material you already have and the part of the shot you need to control.
For text-to-video, describe a coherent action with a readable setting and viewpoint. A scene might show a small sailing boat passing a pier while the camera follows from shore. Specify what moves, which details should remain visible and how the shot ends. Keep the brief focused on observable events rather than a list of unrelated visual qualities.
For image-to-video, prepare a first frame with the intended subject and framing already established. The maker accepts JPG, JPEG, PNG and WebP images smaller than 20 MB, with a short edge greater than 300 pixels and an aspect ratio between 2:5 and 5:2. Use an image whose important contours and features are visible, then describe the motion to develop from it.
Hailuo 02 also has a documented first-and-last-frame mode. Prepare the two images as the intended opening and closing states of one sequence, and describe how the scene moves between them. The first frame determines the framing; the maker states that a differently sized last frame is cropped to match it. Align the images’ composition in advance when a subject must remain visible through the transition.
The prompt can contain up to 2,000 characters. Hailuo 02 supports bracketed camera commands including push, pull, truck, pan, pedestal, tilt, zoom, tracking and a static shot. Commands placed together in a bracket request simultaneous movement; commands placed at different points in the description request a sequence. The maker recommends combining no more than three movements, so choose the camera action that makes the subject easier to read.
Duration and resolution are linked to the mode. Text-to-video documents six or ten seconds at 768P and six seconds at 1080P. Image-to-video also documents 512P for six or ten seconds. The first-and-last-frame workflow documents 768P for six or ten seconds and 1080P for six seconds. Select a supported combination for the shot instead of transferring one mode’s resolution choices to every other mode.
Automatic prompt optimization is a documented control and is enabled by default in the maker’s workflow. Retain its setting when comparing versions, because a rewritten brief changes what the model receives. Keep the exact text, reference frames and selected output settings with the generated clip so a revision can target the action or framing that needs improvement.
Review the whole completed sequence: the opening composition, continuity of the subject, timing of the action and final frame. For a transition, check both endpoints and the motion between them. Save the actual video for editing, together with the prompt and references; use the next revision to address a concrete visual problem such as an obscured detail, an abrupt camera move or an ending that arrives too early.

How the final charge is calculated
The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.
Tariff references do not add request options. Supported parameters are listed for the selected method.
- Fast mode
- Not specified When fast mode is selected
- Flex mode
- Not specified When flex mode is selected
- Maximum reasoning effort
- Not specified When maximum reasoning effort uses the default adjustment
