Seedance 2.5: One Pass, Up to 30 Seconds, Sound Included

Seedance 2.5 is ByteDance's video model built for long single-pass generations: 4-30 seconds per clip, text or image input, synchronized AI audio, and first/last-frame control. AI Fruit runs Seedance 2.5 in its live model catalog - pick it in the generator below, set duration and resolution, check the credit estimate, and generate. This page collects the verified specs, the current limits on each platform, and where the much-advertised 50-reference version actually lives.

Ways to Run Seedance 2.5

The same model is exposed at different depths on different platforms. Pick the route that matches how much input control you need - and what you want to spend.

Generate on AI Fruit

AI Fruit's live catalog carries Seedance 2.5 through its verified KIE contract: text or image input, 4-30 second durations, 480p/720p output, six aspect ratios, an audio toggle, and first/last-frame control. The generator below preselects it and shows an exact credit estimate before you spend anything.

  • 4-30s durations at 480p/720p
  • Credit estimate before generation
  • Audio toggle and last-frame control

Call the model via the KIE API

The KIE API that AI Fruit uses also exposes the model's full multimodal reference pipeline: a Reference-to-Video mode that accepts up to 30 reference images, 10 video clips, and 10 audio clips per request, plus 1080p output, mp4/mov formats, and a web-search flag for grounded prompts. Reference mode is mutually exclusive with first/last-frame image-to-video.

  • Multimodal reference-to-video
  • Up to 1080p, mp4/mov output
  • Web-search-grounded prompts

Third-party apps (advertised specs vary)

Hosted tools market their own Seedance 2.5 versions: MITO advertises up to 50 multimodal references and 4K output, and other portals bundle the model with their own limits and subscriptions. Advertised specs and commercial terms differ per platform, so check each provider's current terms before committing a project to one.

  • MITO advertises 50 references / 4K
  • Each portal sets its own caps
  • Terms vary by provider

What Seedance 2.5 Actually Changes

Seedance 2.5's headline is length with control: one continuous generation instead of a stitched relay of short clips.

Up to 30 seconds in one pass

Older Seedance models in AI Fruit's catalog top out at 4 seconds per clip (2.0 Mini, 2.0 Fast) or 15 seconds (2.0). Seedance 2.5 generates 4-30 seconds in a single pass, which keeps motion, lighting, and subject continuity inside one generation instead of hoping stitched clips match.

Multimodal reference inputs on the raw model

Beyond text and images, the model's Reference-to-Video mode takes reference video clips and audio alongside images, so a character's face, a camera move, and a voice can all enter one request. On the KIE API that means up to 30 images, 10 videos, and 10 audio clips; AI Fruit's editor exposes the text and image paths.

Synchronized audio and last-frame control

An audio toggle generates sound with the picture instead of leaving clips mute, and first/last-frame inputs pin both ends of the clip - drop in an opening frame and a target end frame to control where the shot lands.

Camera direction with lens locking

The model parses camera language - push-ins, tracking, pulls - and supports lens locking for shots that need to stay optically stable, which matters when a 30-second take has to hold together.

How to Generate with Seedance 2.5 on AI Fruit

This workflow follows AI Fruit's current editor configuration - pick the model, set the frame, check the price, generate.

1

Open the generator with Seedance 2.5 preselected

The editor below loads Seedance 2.5 from the live catalog: a 4-30 second duration control (5s default), 480p/720p resolution, six aspect ratios from 16:9 to 21:9, and audio generation on by default.

2

Write the prompt and set the frame

Describe the subject, the motion, and the camera move in plain shooting language. For image-to-video, supply a first frame to animate and optionally a last frame to steer where the clip ends - useful for loops and matched cuts.

3

Check credits, then generate

AI Fruit prices Seedance 2.5 dynamically by duration and resolution: a 5-second 720p clip (the default settings) costs 210 credits, 5 seconds at 480p costs 94, and a full 30-second take runs 560 credits at 480p or 1,260 at 720p. The editor's live estimate shows the exact number before you generate.

Seedance 2.5 Prompt Tips

Long one-pass clips reward structure. These four habits map directly to the model's verified controls.

Direct the camera like a shot list

Name the move and the lock: "slow push-in from counter level", "locked-off frame, no camera shake". Seedance 2.5 parses camera language and supports lens locking, so explicit direction beats hoping the default camera behaves over 30 seconds.

Structure long clips in timed beats

For anything past 10 seconds, write the take in blocks - [0-8s] setup, [8-16s] turn, [16-30s] payoff - with one primary change per beat. A 30-second generation with no internal structure usually drifts; a timed brief gives the model a spine.

Use frames for endings, references for identity

A last-frame image pins where the shot lands; a first-frame image pins where it starts. For character or product identity across many clips, the reference pipeline (images, videos, audio) is the tool - on AI Fruit that means image references today, with the full multimodal set on the KIE API.

Say what should be heard

Audio generation is a toggle, not an afterthought: name the ambience, the impact sounds, or the dialogue in the prompt when you want sound designed, and switch the toggle off explicitly when you plan to add your own track.

Seedance 2.5 FAQ

Seedance 2.5 is ByteDance's video generation model built for long single-pass output: up to 30 seconds per generation, with text or image input, synchronized AI audio, first/last-frame control, and a multimodal reference mode on the raw model. AI Fruit runs it through its verified KIE contract.

Yes. Seedance 2.5 is in AI Fruit's live model catalog, and the generator on this page preselects it. You get 4-30 second durations, 480p/720p output, six aspect ratios, an audio toggle, and a live credit estimate before generation.

The current AI Fruit configuration uses 94 credits for 5s at 480p; 210 credits for 5s at 720p. The default settings cost 210 credits; review the live estimate before generation.
