Seedance 2.5

Seedance 2.5 is ByteDance's multimodal AI video model that turns text, images, video, audio, and 3D models into 30-second 4K clips with synchronized native audio.

What is Seedance 2.5?

Seedance 2.5 is a browser-based AI video generator from ByteDance, the successor to Seedance 2.0. It takes up to 50 multimodal references—text prompts, still images, video clips, audio files, and 3D white models—and fuses them into a single joint input to produce cinematic video. You can access it at seedance25ai.app and use the text-to-video generator for free with sign-up credits. The model runs in a web app and is also exposed through a developer API for programmatic generation.

Key Features

Key differentiators include multimodal reference fusion, native audio, and long-form 4K output.

• 30-second 4K generation — Produces single clips up to 30 seconds long at native 4K resolution (3840×2160) in one pass, no stitching required.
• Native audio-video sync — Dialogue with lip-sync, sound effects, and background music are created together with the picture, so timing matches perfectly.
• 50 multimodal references — Combine up to 50 images, videos, audio, text, or 3D white models in a single generation to lock characters, wardrobe, environments, and lighting.
• Multi-shot consistency — Maintains character appearance, camera style, and visual tone across multiple clips, enabling storyboard-to-video conversion.
• Text-to-video and image-to-video — Start from a natural-language prompt or an anchor image, with first-frame/last-frame control for image-to-video.
• Reference-guided editing — Upload an existing clip to extend, restyle, replace characters, or restage scenes while preserving the rest of the frame.
• API for automation — Endpoints for text, image, transition, and fusion generation let teams batch-generate video at scale with configurable resolution, duration, aspect ratio, and audio.
• Free credits on sign-up — New accounts get free credits to try Seedance 2.5 without a credit card.

Who is it for?

Seedance 2.5 is well suited to roles that need fast, repeatable video creation from written scripts or visual references.

• Social media marketers — Draft short-form concepts for TikTok, Instagram Reels, and YouTube Shorts, producing multiple variations and adapting aspect ratios per platform.
• E-commerce teams — Turn product images into animated video drafts to test presentation styles, visual angles, and seasonal promo ideas.
• Filmmakers and video producers — Use storyboard-to-video to create pre-visualizations and keep multi-shot scenes consistent before production.
• Business presenters — Create video drafts for decks, training materials, and internal updates with cohesive branding.

What can you do with Seedance 2.5?

The model handles a variety of production tasks, from concept testing to post-production editing.

• Test ad concepts quickly — Generate several 4K versions of the same brief and compare them side by side before committing to a final export.
• Animate product photos — Upload a still image and use image-to-video to create a short product demo with fluid, natural motion.
• Restyle existing footage — Use video-to-video editing to change the look of a clip, swap characters, or extend its duration while keeping the rest of the frame consistent.
• Visualize scenes before production — Convert storyboard prompts into rendered pre-visualizations with automatic cross-shot coherence.

How does Seedance 2.5 work?

Seedance 2.5 runs through a three-step browser workflow: set a brief, generate, and refine. First, set the brief by writing a natural-language prompt or uploading reference materials such as images, audio, clips, or 3D models. Second, choose text-to-video, image-to-video, or multimodal mode, set resolution (up to 4K) and aspect ratio, then generate your first cut. Third, refine and export: adjust prompts, swap references, compare side-by-side versions, and export when the output matches your creative brief.

Can Seedance 2.5 edit existing videos?

Yes. Seedance 2.5 supports video-to-video editing: you can upload an existing clip to extend its duration, restyle the look, swap or replace characters, or restage the scene. Reference-guided editing keeps the rest of the frame consistent while you make targeted changes.

How many reference materials does Seedance 2.5 support?

Seedance 2.5 supports up to 50 multimodal references in a single generation — any mix of images, video clips, audio, text, and 3D white models. Joint input fuses them together, allowing you to lock characters, wardrobe, environments, and lighting before rendering.

What is the maximum video length and resolution?

Single clips can be up to 30 seconds long at native 4K (3840×2160) resolution, generated in one pass with synchronized audio. For longer pieces, you can chain and extend clips on the timeline while maintaining multi-shot consistency.

Is there a Seedance 2.5 API?

Yes. The Seedance 2.5 API offers endpoints for text-to-video, image-to-video, and video-to-video generation, letting developers and enterprises batch-generate video at scale. You can configure resolution up to 4K, clip duration, aspect ratio, and native audio output per request.
