Capabilities

Direct longer stories with coordinated visual and audio control

Continuous Narrative

Provider demonstrations show an approximately 30-second sequence moving through several environments while maintaining a readable lead subject, connected camera movement, and deliberate visual transitions.

Timeline Direction

Organize actions, camera changes, scene transitions, dialogue, and sound cues around specific moments to give longer creative briefs a clearer narrative structure.

Multimodal Guidance

Combine written instructions with visual, motion, and audio material to communicate subject appearance, environment, performance, camera language, rhythm, or sound direction.

Audiovisual Performance

Official examples combine moving subjects with speech, music, ambience, and effects, supporting concepts in which visual action and sound must develop together.

Multilingual Scenes

A provider-selected demonstration presents spoken performance across multiple languages with corresponding visible mouth movement, music, and coordinated scene changes.

Selective Revision

Demonstrated editing behavior can target an unwanted scene element while attempting to retain the useful protagonist, framing, and camera motion around it.

Notes & FAQ

Seedance 2.5 generation and publishing guidance

Notes

APIXO supports fixed Seedance 2.5 durations from 4 to 30 seconds and dynamic duration. Dynamic requests reserve 30 output seconds and settle to the actual successful result.

The upstream model supports up to 30 image references, 10 video references, and 10 audio references in one generation. Assign every source a clear role and avoid conflicting instructions.

Timestamp-level editing provides more focused control over selected moments but does not guarantee that surrounding frames, sound, or scene details will remain completely unchanged.

References guide identity, appearance, movement, camera behavior, voice, sound, and style, but do not guarantee exact preservation of people, products, typography, logos, materials, or geometry.

Review anatomy, hands, object contact, rapid movement, scene transitions, occlusion, dialogue, pronunciation, speaker consistency, and audiovisual synchronization before publication.

APIXO exposes text-to-video, first-and-last-frames, and omni-reference modes with 480p, 720p, or 1080p output in MP4 or MOV format.
