Prompt

A three-shot story at dusk: a girl in a yellow raincoat runs down a rainy Tokyo side street, neon signs glowing; cut to her ducking under a ramen shop awning and shaking the water off her hood; cut to a warm close-up as she smiles at the cook and says "One bowl, please." Rain on the awning, sizzling broth, soft city noise.

Seedance 2.5 features

What Seedance 2.5 does well, and what to lean on when you write prompts for it.

30-second stories in one take

Seedance 2.5 generates up to 30 seconds in a single pass, twice the 15-second limit of Seedance 2.0, so a scene keeps its characters, light and sound. Write the beats in order (“cut to the lamp room”) and they play as shots. A 30-second Flash clip at 480p costs 1260 credits.

Dialogue, effects and music

Speech, ambience, sound effects and music are generated with the motion, so the pour, the footsteps or the rain land on the right frame. Put spoken lines in quotes (the chef says “Order up!”), or switch audio off for silent footage.

Animate a photo

Switch to Image → Video and upload a picture: Seedance 2.5 keeps its subject and composition and adds motion and sound from your prompt. Add an optional last frame to control where the shot ends. The clip keeps your image’s framing.

Vertical, square or 21:9

Six aspect ratios for text to video: 9:16, 3:4, 1:1, 4:3, 16:9 and 21:9. Generate 9:16 directly for TikTok, Reels and Shorts instead of cropping a widescreen clip, or 21:9 for a cinematic frame.

Three Seedance 2.5 tiers

The full Seedance 2.5 model for detail up to 1080p, Turbo for HD at a lower price and Flash for the cheapest drafts and long takes. The credit price updates as you change the model, length or resolution.

Pay only for finished videos

Credits are reserved when a clip starts and returned automatically if the generation fails. Every finished Seedance 2.5 video is saved to your history and downloads as an MP4 with its audio track.

What is Seedance 2.5?

ByteDance’s video model for 30-second storytelling with sound — and you don’t need a ByteDance account to use it here.

Seedance is the AI video model family from ByteDance’s Seed team. Seedance 2.5 was previewed at the Volcano Engine FORCE conference on June 23, 2026 and launched on July 31, 2026. ByteDance describes it as “a next-generation audio-video joint generation model, built for 30-second storytelling with precise reference control and powerful editing capabilities.”

Compared with Seedance 2.0, version 2.5 doubles the length of a single generation from 15 to 30 seconds, follows reference footage more precisely and, in ByteDance’s words, makes motion “smoother and more consistent” with more realistic visuals. Because picture and sound are generated together, footsteps, rain, voices and music land on the right frame instead of being added afterwards.

Seedance25Video is an independent web app that runs Seedance 2.5 through an API provider. You get three tiers in one Seedance 2.5 video generator — the full model, Turbo and Flash — with text-to-video, image-to-video, clips from 5 to 30 seconds and output up to 1080p.

Who uses Seedance 2.5

Short-form creators

Generate 9:16 clips for TikTok, Reels and Shorts directly — hooks, B-roll and story beats with the sound already on the track, so a Seedance 2.5 clip can go straight into your edit.

  • TikTok
  • Reels
  • Shorts
  • 9:16 hooks

Ads and social campaigns

Test several versions of one idea before you shoot anything. Change the setting, the light or the line of dialogue in the prompt and compare the takes side by side.

  • Ad variants
  • A/B tests
  • Social posts

Product and e-commerce

Upload a product photo as the first frame and describe a slow turntable, a pour or an unboxing. Short loops work well on product pages and marketplace listings.

  • Product loops

Filmmakers and previs

Block out a scene before the shoot: test framing, lens feel and lighting, or use a 30-second take to rough out a whole sequence with its sound.

  • Storyboards
  • Shot tests
  • Previs

Bringing photos to life

Animate a landscape, a portrait or an illustration from a single image — only with pictures you own or have permission to use.

  • Portraits
  • Landscapes
  • Illustrations

Music and storytelling

Create mood shots and visual loops for songs, podcasts and stories. Mention the sound you want — rain, a crowd, wind, a melody — and it is generated with the picture.

How to use the Seedance 2.5 video generator

From idea to a downloadable clip in three steps — all in the generator at the top of this page.

  1. 1

    Describe the shot or upload a photo

    Write what happens: the subject, the action, the camera move, the light and the sound. To animate a picture, switch to Image → Video and upload it as the first frame (and, if you like, a last frame).

  2. 2

    Pick a model and settings

    Choose Seedance 2.5, Turbo or Flash, then the length (5, 10, 15 or 30 seconds), the resolution and the aspect ratio. The credit price updates as you change them.

  3. 3

    Generate and download

    A 5-second clip usually takes a few minutes; 1080p and 30-second videos take longer. Finished videos are saved to your history as MP4s with audio, and failed ones are refunded automatically.

Seedance 2.5 pricing

Credits per clip on every Seedance 2.5 tier — the same prices the generator above charges. One credit is about one US cent.

Video editing and extension

Editing an existing clip and extending it are Seedance 2.5 features we have not added. Every generation here is a new clip from a prompt or an image.

Seedance 2.5 stops at 1080p

Seedance 2.5 runs at 480p, 720p and 1080p here; 4K is not offered for it. If you need 4K, Seedance 2.0 and Veo 3.1 offer it in their own generators, at a higher price per second.
