MiniMax H3 Max Lip Sync Image to Video Overview

MiniMax H3 Max Lip Sync Image-to-Video turns a source image and audio into synchronized video for avatars, promos, and character clips on each::labs.

A source image and audio track create a lip-synchronized character clip.

MiniMax H3 Max Lip Sync Image to Video from MiniMax is available through each::labs in the minimax-h3-max family. Required fields are image_url, audio_url.

resolution: Output resolution. enable_transcription: Transcribe the supplied audio to guide lip synchronization.

Use the MiniMax H3 Max Lip Sync Image to Video API when you need this transformation or analysis as a repeatable step in an application or creative pipeline. The sections below distinguish the required material, adjustable controls and checks that matter before delivery.

Capabilities

• A source image and audio track create a lip-synchronized character clip.
• resolution: Output resolution.
• enable_transcription: Transcribe the supplied audio to guide lip synchronization.
• enable_safety_checker: Enable content safety checks.
• image_url: URL of the source image to animate.

Use Cases for MiniMax H3 Max Lip Sync Image to Video

MiniMax H3 Max Lip Sync Image to Video is useful when this specific operation fits between source preparation and delivery. These scenarios show how it can support different parts of a working pipeline.

Creators

Animate a character introduction. Use a representative source or a concise brief, then inspect the result before preparing a larger set of assets.

Design and marketing teams

Create an audio-led promo concept. Compare the result with the intended message, composition and destination. Keep reviewable versions of the source and output.

Developers

Visualize approved dialogue using a portrait. Inspect the actual returned value before connecting it to another step, and keep the chosen request settings with the result.

Start with a clear definition of the desired result and use the exposed controls to reach it. Keep any additional generation, editing or application logic in separate steps so that the effect of this operation remains easy to review.

Tips and Tricks

Describe one coherent shot before adding complex action. State the subject, movement, camera behavior and setting separately. For reference-guided requests, choose source images with clear subjects and compatible framing.

• enable_transcription: Transcribe the supplied audio to guide lip synchronization.
• enable_safety_checker: Enable content safety checks.

Set the named operation controls directly. This entry has no general creative-prompt interface; supplying an invented prompt field will not replace a required source or numeric setting.

Compare one deliberate adjustment at a time. Inspect the part of the result affected by that change, then check the rest of the asset or response for unwanted side effects before reusing the settings.

Technical Specifications

• Result type: video.
• Required fields: image_url, audio_url.
• resolution: string; options 480P, 768P, 1080P, 2K; default "768P".
• enable_transcription: boolean; default false.
• seed: integer; minimum 0; maximum 2147483647.
• enable_safety_checker: boolean; default true.

image_url: URL of the source image to animate.

Values must use the types and accepted options listed in the parameter reference. A displayed default does not remove a required-field requirement. Choose a supported output setting for this entry rather than borrowing a preset from a related model.

Things to Be Aware Of

Watch the entire clip rather than reviewing only a thumbnail. Check subject identity, object boundaries, motion continuity, camera changes and the ending; review the audio as well when the entry includes it.

Optional settings are not necessarily interchangeable with those on another entry in the same family. Use the accepted names, types and values shown for this operation.

For media-based inputs, supply a directly retrievable file URL rather than a page containing the asset. Keep the source available while processing. Check the final content in the destination player, editor or application, not only the request status.

Key Considerations

Use clear speech and a suitable visible face; inspect mouth timing and identity rather than assuming exact synchronization.

Public estimate: $0.05–$0.32 per second.

Prepare image_url, audio_url before starting. Optional settings include resolution, enable_transcription, enable_safety_checker. Keep these settings aligned with the intended delivery, especially when a later step expects a particular type or format.

Run a representative request before scaling to a larger collection. Judge the result against the source and the brief, and account for all generated outputs or usage-sensitive options when estimating a batch.

Limitations

• resolution: allowed values: ["480P", "768P", "1080P", "2K"].
• seed: minimum: 0; maximum: 2147483647.

Unsupported parameters do not establish additional capabilities. A generated result can differ from the intended brief, so review detail and consistency before publication.
