Seedance 2.5 — 30 Seconds of Video in One Take

Seedance 2.5 is ByteDance's latest video model: a full 30 seconds in one take, up to 50 reference files, and native audio in 10+ languages. Start with free credits.

What is Seedance 2.5?

Seedance 2.5 is ByteDance's video generation model, announced at the company's FORCE conference in June 2026 and available on this platform today. It renders up to 30 seconds of continuous video in a single generation, accepts up to 50 reference files across image, video, and audio, and produces native audio in 10+ languages. Unlike a sequence of short clips stitched together, one Seedance 2.5 take holds the same camera, cast, and lighting from the first frame to the last.

30 Seconds, One Take

Seedance 2.5 renders a full 30-second scene in a single generation. No stitching short clips together, no continuity breaks between cuts.

Timestamp-Level Direction

Write what happens at second 4, second 11, second 20. Seedance 2.5 follows the timing you specify instead of interpreting the whole prompt at once.

50 Multimodal References

Attach up to 50 images, video clips, and audio files to lock character identity, products, movement, and tone across a scene.

Region-Level Editing

When a label, face, or background needs work, select that area and describe the correction. The rest of the clip — timing, composition, audio — stays untouched.

Made with Seedance 2.5

Real generations across five categories. Hover to preview, click to watch full size.

Why Seedance 2.5 matters for video creators

Longer takes and tighter direction change what you can finish in one sitting with Seedance 2.5. Here is how the Seedance 2.5 upgrade lands for people already working on the platform.

Short clips force you to cut, match, and hope the character still looks the same. A 30-second single take from Seedance 2.5 removes the stitching step entirely — lighting, faces, and motion stay continuous because they were never separate.

Most re-rolls happen because the action landed at the wrong moment. Seedance 2.5 accepts direction tied to specific seconds, so you fix the beat instead of regenerating the whole scene and hoping.

The biggest complaint in AI video is that characters look different in every generation. Seedance 2.5 accepts up to 50 reference files, so a person, a product, or a visual style holds across every clip you make from them.

Seedance 2.5 FAQ

Answers on availability, clip length, references, and pricing.

Yes. Seedance 2.5 is live on this platform — sign up, claim free trial credits, and you can generate with it today. ByteDance announced the model at its FORCE conference in June 2026 and has not published a separate consumer release date.

Up to 30 seconds in a single generation, which is the headline change over Seedance 2.0. Because Seedance 2.5 renders one continuous take instead of stitched segments, characters, lighting, and camera motion stay consistent from the first second to the last. For a talking-head explainer or a product spot, that usually means one render replaces a four-clip edit.

Resolution depends on the tier you pick in the generator, not on the model version alone. Standard, Fast, and Mini render at 480p and 720p; the Portrait tier goes up to 1080p and 4K. The selector above shows exactly what each tier supports before you spend a credit, so check it there rather than assuming a ceiling.

Up to 50 multimodal references — images, video clips, and audio. Use them to lock character appearance, products, movement style, and tone across every generation.

Yes. Seedance 2.0 stays available with text-to-video, image-to-video, reference-guided generation, video editing, and beat-sync. It remains the faster, lower-cost choice for standard clips; Seedance 2.5 is built for long, reference-heavy work.

New accounts get free trial credits — enough to test Seedance 2.5 with real prompts before paying. Paid plans add more credits and higher monthly volume; the pricing page lists current rates per tier.

You write the beats with times attached — the door opens at second 3, the logo lands at second 20 — and Seedance 2.5 follows that schedule instead of averaging your whole prompt across the clip. It matters most on longer scenes, where one mistimed action used to mean regenerating the entire take.

Yes. Dialogue, sound effects, and ambient audio come out of the same generation as the picture, in 10+ languages, so there is no separate voiceover or sync pass. You can also upload a clip and keep its original audio when you edit.
