One prompt. A 30-second 4K film.

Seedance 2.5 is ByteDance's latest AI video model, unveiled at the Volcano Engine FORCE 2026 conference. It generates a full 30-second video in a single generation at native 4K — no stitching short clips together, and no loss of quality or continuity along the way.

Where most video models still top out at 15–20 seconds per pass, Seedance 2.5 doubles the ceiling and keeps characters, products, and brands consistent across the entire shot. ByteDance skipped 2.1 and jumped straight to 2.5, pushing AI video into what it calls the long-sequence era — long enough for real advertising spots, film pre-visualization, and finished social content rather than short fragments.

Internally positioned as a production-grade tool for film, advertising, and animation, Seedance 2.5 is currently in final testing with a public launch expected in early July 2026.

30-second single-pass video. The longest single generation in the industry. One continuous 30-second shot means smoother camera motion, coherent narrative arcs, and fewer artifacts from merging separate clips.

Native 4K, 10-bit color. Detail is captured at generation time, not upscaled — hair strands, fabric weave, silk-thread direction all render with full clarity, with 10-bit color depth for richer grading latitude.

Up to 50 multimodal references. Feed Seedance 2.5 images, video clips, audio, and even 3D white models — up to 50 in a single prompt. Reference a character's face from one image, their wardrobe from five more, camera movement from a clip, and a mood track from audio; the model resolves all of it into one coherent output.

Multi-shot storytelling. Direct multiple scenes, camera moves, and transitions from a single description — the model handles staging on its own.

Localized video editing. Change parts of a generated video without reshooting: swap a product while keeping the model's movement identical, replace a background without touching the foreground, or switch a character while preserving the original performance. Ideal for A/B creative and per-SKU e-commerce variants.

Character & brand consistency. Faces, outfits, props, and logos stay stable across the full 30-second sequence.

Industrial-scale applications. Beyond creative work — multi-language product instruction videos, embodied-AI training data across scenes and angles, and extreme-condition simulation for autonomous-driving datasets.

The key differentiator: most models generate a short clip and stop. Seedance 2.5 generates a complete scene — 30 seconds, 4K, multi-shot, editable, and consistent — so you produce finished output instead of fragments to stitch together.

Practical advantages:

• One take, not many cuts — every clip boundary is a continuity risk; a single 30s pass removes them
• Up to 50 references — combine characters, wardrobe, camera, audio, and 3D layout in one prompt
• Edit by describing it — local, chat-style edits beat re-rolling an entire clip for a small fix
• Built for commercial use — every output ships with a commercial license

1. Visit the site. Open seedance2-5.app — runs in the browser, no install. Start for free, no credit card required.

2. Pick your starting point.

• Text-to-video — describe the scene in natural language
• References — attach images, clips, audio, or 3D white models (up to 50) and @-mention them in your prompt
• Editing — generate a clip, then refine specific parts without reshooting

3. Write a detailed prompt. Specify subject, action, camera framing (close-up, wide, tracking), lighting (cinematic, soft, golden hour), and aspect ratio (16:9, 9:16, 1:1). Use @ references to lock characters, style, or camera movement.

4. Generate, then refine. Get a full 30-second 4K result, then make localized edits — "swap the product", "warmer lighting", "replace the background" — leaving the rest of the shot untouched.

5. Export and share. Download in your chosen aspect ratio at native 4K, ready for YouTube, TikTok, Reels, advertising, or broadcast — commercial license included.
