From a portrait, product shot, or illustrated character, Seedance 1.5 Pro builds lifelike motion while preserving style, structure, and identity. With optional start and end frames, your image-to-video sequence can open and close on precise compositions, letting the model generate the motion path in between with smooth, cinematic continuity.
Seedance 1.5 Pro creates voices, ambient layers, and spatial sound directly within the visual generation process, allowing text-to-video and image-to-video scenes to land with smooth timing and clean emotional flow. Lip movements match speech across multiple languages and dialects, creating natural, story-ready audio-visual alignment.
Prompts are interpreted with a cinematic sense of framing, from close-ups capturing subtle expressions to full-shot sequences with rich atmosphere and carefully balanced composition. Camera paths — pans, push-ins, or orbits — give Seedance 1.5 Pro text-to-video outputs a polished, film-like rhythm suited for narrative scenes and commercial visuals.
When animating from portraits or character art, Seedance 1.5 Pro preserves identity while shaping coherent performances across gestures, emotions, and narrative beats.

Gestures, posture changes, and full-body movement follow a smooth rhythm, allowing Seedance 1.5 Pro to handle dance, action, and performance-driven video generation with strong continuity. Both text-to-video prompts and image-to-video sequences benefit from motion that stays proportional and character-accurate.
Seedance 1.5 Pro maintains spatial clarity by keeping backgrounds stable even when characters move, helping image-to-video outputs look clean and well-composed. This is especially useful for product-focused shots, lifestyle visuals, and any scene where consistent framing anchors the viewer’s attention.
Ambient layers, tonal cues, and subtle Foley match the pacing and emotion of the generated footage, giving Seedance 1.5 Pro video outputs a more immersive quality. Whether it's a cinematic product moment or a text-to-video narrative, the audio presence strengthens mood and storytelling.
Speech pacing, eye movement, and head gestures stay clear and consistent in both image-to-video and text-to-video workflows. This makes Seedance 1.5 Pro ideal for explainers, avatar content, localized talking-head videos, and any format requiring stable identity with clean vocal alignment.
Seedance 1.0 Lite marked the beginning of the Seedance family, introducing reliable text-to-video and image-to-video generation at 1080p. It delivered stable motion, handled both subtle and large-scale actions, and maintained narrative coherence across multi-shot sequences. While stylistically flexible and capable of strong prompt adherence, its focus remained on visual generation only, laying the groundwork for future enhancements in realism, consistency, and multi-scene storytelling.
Seedance 1.0 Pro expanded on Lite’s core strengths with more refined physical realism, stronger stability during complex movements, and improved continuity across shots. It supported diverse artistic styles, interpreted camera directions more accurately, and delivered competitive aesthetic quality in benchmarks. With better prompt understanding and stronger I2V identity preservation, Seedance 1.0 Pro represented a significant step toward cinematic video generation, though still limited to silent outputs.
Seedance 1.5 Pro marked a major leap in the series, becoming the first version to generate audio and video together in a single pass. With cinema-level camera control, millisecond-accurate lip-sync, multilingual speech support, and stable character identity across scenes, Seedance 1.5 Pro redefined what AI video generation could achieve. It enabled storytellers to produce expressive dialogue, synchronized sound effects, atmospheric audio, and cohesive multi-shot narratives—all from text or images—ushering the Seedance line into fully integrated, performance-ready video creation.
Follow these simple steps to get started with our platform.
Begin by introducing the source of your idea: a short written scene for text-to-video creation, or a still portrait or product photo for image-to-video animation. This starting point tells Seedance 1.5 Pro what kind of moment you want to bring to life.
Add the elements that define how the moment unfolds — dialogue, language, camera direction, or start–end frames for more controlled I2V transitions. Seedance 1.5 Pro reads these cues to align expression, timing, and movement in a coherent way.
Generate your clip and preview the audio-synced motion, visual pacing, and identity stability. If you want a different tone, rhythm, or camera feel, simply adjust your description or frames and create a polished version through Free Seedance 1.5 Pro on VidFul.ai.
