Its headline upgrade is 30-second native generation in one take — double Seedance 2.0 — together with up to 50 multimodal references (30 images, 10 video clips and 10 audio clips), timestamp-level local editing and stronger shot transitions.
For short-form creators, 30 seconds covers an entire Reel or UGC ad in a single coherent generation. Rekreate offers Seedance 2.5 at 4–30 seconds in 720p or 1080p.
- Launched: July 31, 2026 (announced June 23, 2026).
- Length: up to 30 s per generation; multi-round extension toward multi-minute videos.
- References: up to 30 images + 10 videos + 10 audio clips.
- Editing: timestamp-level local edits without regenerating the whole clip.
- In Rekreate: 4–30 s, 720p or 1080p, up to 50 references.

What's new in Seedance 2.5
ByteDance framed Seedance 2.5 around "one-take creation" and "flexible referencing":
- 30-second single pass. Most models top out at 8–15 seconds, forcing you to stitch clips and fight consistency drift. Seedance 2.5 keeps characters, scenes and audio coherent across a full 30 seconds.
- Multi-round extension. Extend a generation several times while preserving identity and sound; ByteDance's apps offer a beta long-video mode reaching around three minutes.
- 50 references. Combine a cast of characters, several products, locations, motion references and audio in a single brief.
- Local editing with timestamps. Change what happens between, say, 12 and 16 seconds — swap an object, fix a gesture — without regenerating everything.
- Director-grade camera control. Better shot transitions, scene changes, green-screen and perspective handling, plus camera paths described in prompts or via clay-render references.
- Improved audio consistency for dialogue and music across longer videos.

Prompting a 30-second Seedance 2.5 video
Longer generations need clearer structure. Write the prompt like a mini storyboard with timestamps:
Format: vertical 9:16 UGC ad, natural daylight, handheld feel. 0–3 s (hook): Close-up of @image_1 looking into camera: "I stopped buying five different serums." Quick push-in. 3–12 s: She holds @image_2 next to the old bottles on the counter, sweeps them into a basket. Light upbeat music starts. 12–22 s: Macro shots of the texture on her hand, then applying it; soft voice-over explaining the three benefits. 22–30 s: Mirror shot, smiling, holding @image_2 to camera: "Link's in bio." Music resolves.
Tips:
- Put the hook first and keep it under three seconds.
- Assign every reference a role and use the same tag consistently.
- Describe audio per segment — dialogue lines in quotes, music changes, SFX.
- Use local editing for fixes instead of rerunning all 30 seconds.
