Latest Release
What's new in Seedance 2.5
Three concrete upgrades the new model brings to this tool.
When you generate inside this Seedance 2.5 tool, you get three things Seedance 2.0 couldn't do: a 30-second native clip in a single render (up from ~15 seconds), up to 50 multimodal references in one job (up from 12), and roughly 20% better prompt adherence.
Five feature cards below break down what each upgrade unlocks in production.

Key Features
Seedance 2.5 key features
Five features define what you can do in this Seedance 2.5 tool.
Feature 1
30-second native single-clip output
Generate a full 30-second clip in one render - no patching two short clips into one, no continuity drift between halves. Inside this tool you write one brief, hit generate, and the entire shot comes back as a single file.

Feature 2
50 multimodal references in one job
Drop up to 50 references - text, images, audio, video, and 3D white-model blockouts - into a single Seedance 2.5 brief. Tag each one by role so the model holds every reference in its assigned slot for the full clip.

Feature 3
Finer motion and camera control
Seedance 2.5 reads directional language more literally than 2.0. Slow dolly in, hold on the door, push past camera at second 12 - the kind of phrasing a director would write - translates to the render.

Feature 4
~20% better prompt adherence
Roughly 20% more of what you write makes it into the render, compared to Seedance 2.0. Style language and edit language translate to the clip more reliably. Less prompt rewriting; more first-try matches.

Feature 5
Multi-shot character consistency
Pin a character with up to a dozen reference shots in one Seedance 2.5 brief. Across angles, lighting changes, and outfits, the lead looks like the same person from frame to frame.

Supported Inputs & Outputs
What you can create with Seedance 2.5
Inputs, formats, resolutions, and languages most teams need from an AI video generator.
Input modes
Text prompts, reference images, audio clips, source video, and 3D white-model blockouts. Combine up to 50 in a single Seedance 2.5 brief.
Resolution
720p, 1080p, and native 4K. The same generation works for a phone vertical and a large-screen hero loop.
Aspect ratios
16:9 widescreen, 9:16 vertical, 1:1 square, 4:3 legacy. Pick the format in the brief.
Clip length
Up to 30 seconds in one native pass. Longer cuts via the extend flow.
Languages
Multilingual prompts - English, Chinese, Japanese, and Korean.
Use Cases
Who Seedance 2.5 is built for
Four scenarios where a 30-second 4K shot, multi-reference control, or finer editing actually matters.

Marketing teams shipping short-form social
A single 30-second Seedance 2.5 render is the full unit a TikTok, Reel, or YouTube Short needs - no second extension job, no continuity drift.

Filmmakers and pre-visualization artists
Pre-viz a scene before going to set, then iterate on shot lists without burning camera time. A 3D blockout pinned to the brief gives the director a real camera path.

Brand and content teams running multi-shot campaigns
Lock a brand character, location, props, and color palette in one Seedance 2.5 brief. The 50-reference budget is what makes this practical.

Solo creators and indie studios
Free credits cover trial runs; paid tiers give you native 4K, the full 30-second cap, and commercial-use rights.

02
Attach references — up to 50 in one job
Drag in any combination of text, images, audio, video, and 3D white-model blockouts. Tag each one by role: character, location, motion style, color palette.

FAQ
Seedance 2.5 FAQ
Quick answers before you generate your first Seedance 2.5 video.
Seedance 2.5 is the latest AI video generation model in the Seedance family, the same lineage as Seedance 2.0 and 1.5 Pro. It accepts text, images, audio, video, and 3D white-model blockouts as input, and produces a 30-second clip in native 4K from a single prompt - no second pass to extend, no separate upscaling step. In this tool, you run Seedance 2.5 directly in your browser: write a brief, attach up to 50 references, and download the finished clip. The three concrete things Seedance 2.5 gives you over Seedance 2.0 are doubled native clip length (30s vs 15s), a much larger reference budget (50 vs 12), and roughly 20% better prompt adherence - fewer rewrites to land a specific shot.
You sign in, pick Seedance 2.5 as the model, write your brief, optionally attach up to 50 references, and submit. The tool sends the job to the Seedance 2.5 model, then returns a 30-second 4K MP4 you can preview in the browser and download. Render takes a few minutes; the exact time depends on your tier and the current queue. You don't install anything - everything runs in the browser tab.
Yes - new accounts get free Seedance 2.5 credits to try the tool with no card. Free-tier renders cap at 720p, 16:9, with a small watermark. Paid credit packs remove the watermark, unlock higher resolutions and the full 30-second clip length, and add commercial-use rights. See the Pricing section for exact credit counts.
Yes - Seedance 2.5 renders in 4K natively on paid tiers, not through a separate upscaling pipeline. The same render covers 720p, 1080p, and 4K - you pick the output resolution in the brief. Aspect ratios supported are 16:9 widescreen, 9:16 vertical, 1:1 square, and 4:3 legacy.
A "3D white model" is a simple, untextured 3D blockout of your scene - geometry only, no shading, no lighting, no materials. You drop it into Seedance 2.5 as one of your reference inputs, and the model uses the geometry as the spatial scaffold: camera paths track the blockout, subject blocking respects the volumes, and the final composition lands on your intended framing.
Up to 50 on paid tiers. The references can be any mix of text snippets, images, audio clips, source video, and 3D blockouts. Each one is tagged with a role - character, location, motion style, color palette, blocking scaffold, audio bed - and the model holds each one in its assigned slot for the full clip.
The native single-clip ceiling is 30 seconds. For anything longer, you chain extensions: render the first 30 seconds, then use that clip as the seed for the next segment. If continuity matters across a long cut, render several 30-second Seedance 2.5 clips that share the same references, then edit them together in post.
Free-tier renders carry a small corner watermark. Paid tiers remove the watermark entirely. Past Free-tier renders stay watermarked, but new renders after upgrade are clean.
Yes on paid tiers - each includes a commercial-use license that covers ads, brand content, client work, and paid social posts. The Free tier is personal-use only.
