Seedance 2.5 AI video generator

Seedance 2.5 is ByteDance's newest video model, and the first in the KreatorFlow studio that makes a single clip of up to 30 seconds. Describe the shot, add images, clips or a saved character as references, and render in 480p, 720p, 1080p or 4K with generated audio.

What Seedance 2.5 is good at

Seedance 2.0 and the other studio models stop at 15 seconds, which forces longer ideas into several generations that then have to be cut together. Seedance 2.5 lets you ask for 30 seconds in one shot, so a walk through a location, a product demo, a slow reveal or a short dialogue beat can play out as one continuous take with the same lighting and the same subject from start to finish.

It follows camera direction written in plain language: a slow push-in, an orbit, a crane down or a handheld feel. It also reads references. Add up to 9 images for faces, products or style, up to 3 clips for motion, and up to 3 audio files for rhythm or voice, or call a saved character by its @handle to keep the same person on screen.

In the studio, Seedance 2.5 sits next to Seedance 2.0, Seedance 2 Fast and Seedance 1.5, so you can draft an idea cheaply on a faster model and switch to 2.5 when you need the length.

How Seedance 2.5 compares with Seedance 2.0

Seedance 2.0 is the previous model. Both sit in the same model menu and take the same references.

The difference is length: Seedance 2.5 renders up to 30 seconds in one take and accepts longer audio references, while Seedance 2.0 stops at 15 seconds and costs fewer credits per clip. Draft short tests on 2.0 and switch to 2.5 when the shot needs the time. See the Seedance 2.0 video generator for the shorter model.

How to make a Seedance 2.5 video

  1. 1

    Pick Seedance 2.5

    Open the video studio, choose Seedance 2.5 in the model menu and pick text to video or add a starting image.

  2. 2

    Describe the whole shot

    Longer clips need a plan for the full length: say what happens at the start, the middle and the end, and how the camera moves between them.

  3. 3

    Set length and quality

    Choose up to 30 seconds, a resolution and an aspect ratio. The credit cost updates as you change settings, and nothing is charged until you confirm.

Prompting tips for 30-second clips

Write the clip as a short sequence of beats rather than one sentence. For example: the camera starts wide on a quiet street at dusk, pushes slowly towards a lit cafe window, then drifts inside to settle on a barista pouring latte art. One subject and one continuous camera path keep long clips coherent; several unrelated actions in one prompt tend to blur together.

If the same person has to appear in several clips, create them once in the AI character generator. To animate a photo you already have, start from image to video. For ready-made camera moves, the video effects templates set everything up for you.

Seedance 2.5 prompt examples

Each prompt describes one continuous take from start to end. Copy one and change the subject, place and camera path.

  • One-take location walk

    Wide shot of a quiet street at dusk. The camera pushes slowly towards a lit cafe window, drifts inside past the counter and settles on a barista pouring latte art. Warm practical lights, light rain outside, soft ambient cafe sound.

    Seedance 2.5, 30 seconds, 720p, 16:9.

  • Product reveal

    A matte black wireless speaker on a stone plinth in a dark studio. A thin rim light sweeps across it, the camera orbits half way round, then pushes in on the logo as the speaker pulses with a low bass note.

    Seedance 2.5, 15 seconds, 1080p, 1:1. Add product photos as image references.

  • Vertical story beat

    Handheld close-up of a runner tying her shoes at sunrise, she stands, the camera follows her from behind along a coastal path, then rises to show the sea and the low sun ahead.

    Seedance 2.5, 20 seconds, 720p, 9:16. Use a saved character's @handle for the runner.

  • Music-led montage

    A neon-lit night market seen through one smooth crane shot: steam from food stalls, people laughing, lanterns swaying, the camera rising above the crowd on the final beat.

    Seedance 2.5, 30 seconds, 720p, 21:9. Add a track as an audio reference for the rhythm.

Seedance 2.5 questions

What is Seedance 2.5?

Seedance 2.5 is the newest video generation model from ByteDance. KreatorFlow is an official BytePlus partner, built on BytePlus, and runs Seedance 2.5 in its video studio next to Seedance 2.0. Its headline change for creators is length: one generation can run for up to 30 seconds.

How is Seedance 2.5 different from Seedance 2.0?

Seedance 2.0 makes clips of 4 to 15 seconds; Seedance 2.5 goes up to 30 seconds in one shot. Both take the same references (9 images, 3 clips, 3 audio files) and render 480p to 4K. Seedance 2.5 costs more per second, so Seedance 2.0 and Seedance 2 Fast remain the cheaper choice for short clips and drafts. Editing an existing video (transform, restyle, extend) still runs on Seedance 2.0.

How many credits does a Seedance 2.5 video cost?

A 5-second clip costs 20 credits at 480p, 20 credits at 720p, 50 credits at 1080p, 120 credits at 4K. At 720p, 5 seconds costs 20 credits, 15 seconds costs 60 credits, 30 seconds costs 120 credits. Generated audio does not change the price. The studio shows the exact cost before you generate, and failed jobs are refunded automatically.

Which plan do I need for Seedance 2.5?

Seedance 2.5 needs a plan, starting with Creator, which renders up to 720p. Pro, Max and Business also render 1080p and 4K. New accounts get 75 one-time starter credits for images and video. Free video covers Seedance 2 Fast and Seedance 2.0 Mini at 480p only, queued and rate limited. Other video models and 720p and above need a plan.

How long can a Seedance 2.5 video be?

One generation can be 4, 5, 6, 8, 10, 12, 15, 20, 25, 30 seconds long, so up to 30 seconds in a single take. Seedance 2.0 stops at 15 seconds.

Can Seedance 2.5 follow an audio reference?

Yes. Add up to 3 audio files for rhythm, music or voice. On Seedance 2.5 each one can be 2 to 30 seconds long; on Seedance 2.0 the limit is 15 seconds.

Which aspect ratios does Seedance 2.5 support?

16:9, 4:3, 1:1, 3:4, 9:16, 21:9. Jobs anchored on a frame or a video reference follow the aspect ratio of your input.

Does Seedance 2.5 add a watermark?

No. KreatorFlow requests every Seedance render with the provider watermark switched off and adds no logo of its own, so the clip you download is clean.

Is Seedance 2.5 available through an API?

Yes. The KreatorFlow developer API exposes it as kreator-video-seedance-2-5 for clips of up to 30 seconds at 480p, 720p or 1080p, billed in prepaid tokens. See the Seedance API page for details.
