What is new in Seedance 2.5

Officially launched by ByteDance Seed on July 31, 2026, Seedance 2.5 advances long-form storytelling, multimodal referencing, and precision editing.

Up to 30 seconds in one generation

Create a complete audio-video scene up to 30 seconds in a single pass, with room for performance, camera movement, dialogue, and a more developed narrative beat.

Longer stories with stronger continuity

Maintain a more consistent audiovisual language across shot transitions and scene changes, then use multi-round extension in supported official products to build multi-minute work.

Expanded official reference capacity

The official Seedance 2.5 model accepts up to 30 images, 10 videos, and 10 audio clips in one generation, helping it understand complex subjects, scenes, props, and creative intent.

Smarter multimodal understanding

Reference composition, character identity, voice, style, motion, camera language, sound, and scene structure instead of relying on a single image or a loosely interpreted prompt.

Timestamp-level direction and editing

Use chronological instructions to place actions, dialogue, camera changes, and transitions at specific moments, and target selected audio-video segments with greater precision.

Native synchronized audio

Generate picture and sound together so speech, ambience, music, effects, and movement share the same timing and creative direction.

Professional editing controls

Seedance 2.5 strengthens reference-based editing, green-screen workflows, camera perspective changes, and targeted creative adjustments for film and advertising production.

Practical controls in this workspace

The current integration offers 1–30 second MP4 output at 480p or 720p, optional audio and web search, frame-based modes, and up to 9 images, 3 videos, and 3 audio references.

How to use Seedance 2.5

Plan and generate a longer synchronized sequence in three steps.

Set the format and duration

Choose text, first frame, first and last frames, or multimodal reference. Keep Seedance 2.5 selected, then set an output length from 1 to 30 seconds, 480p or 720p resolution, aspect ratio, and audio.

Direct the sequence over time

Describe subject, performance, camera, lighting, and sound in chronological order. Use time ranges such as 0–5s and 5–10s, then add references that clarify identity, movement, style, or rhythm.

Generate and refine the complete beat

Review continuity, timing, and audio sync across the full sequence. Adjust only the sections that need work, then download the final MP4.
