Capability Index

Features grouped by what they do

Generation, references, motion/audio, and production tools—so you can find the limit that matches your brief.

Generation & Output

30-second single-shot render
One native pass, no manual stitching between clips.
Fast vs Standard render modes
Trade render speed for fidelity depending on the draft stage.
480p through native 4K
Draft cheap, deliver at full resolution once a brief is locked.

Reference & Consistency

50-input multimodal references
Images, video, audio, and 3D blockouts in one job, tagged by role.
Character swap & consistency
Hold a character's look across camera angles and the full clip length.
Video extension workflows
Use an existing clip as a motion or style reference to continue a scene.

Motion, Camera & Audio

Directional camera control
Written camera language (dolly, pan, hold) translates more literally than 2.0.
Native audio sync
Footsteps, ambient tone, and dialogue-friendly lip movement generated with the video.
~20% better prompt adherence
Complex, multi-instruction briefs land closer to the request on the first try.

Production Tools

3D white-model blockout input
Pre-stage camera position and object scale before the final render.
Post-generation adjustments
Trim, swap a reference, or adjust motion without a full re-render on supported edits.
Region-level frame editing
Target a specific area of a frame rather than regenerating the whole shot.

Three Specs in Action

Key capabilities on screen

Three rows from the table above, each shown in a generated clip—so the limit is concrete, not abstract.

50 references, tagged by role

Every one of the 50 reference slots is assigned a role in the brief—character, location, motion style, palette, or blocking scaffold—so the model knows what each asset controls instead of guessing from context.

Test This Spec

Directional camera language

Written camera instructions—slow dolly in, hold on the doorway, whip pan at second 12—translate to the render more literally than on Seedance 2.0, which is what makes shot-specific briefs practical instead of a lottery.

Test This Spec

3D blockout pre-staging

Feed in a simple 3D mesh to lock camera position and object proportions before spending render credits—useful for product previsualization and architectural flythroughs where spatial accuracy matters more than a purely descriptive prompt.

Quick Delta

Spec delta vs Seedance 2.0

Spec	Seedance 2.0	Seedance 2.5
Native clip length	~15 seconds	30 seconds
Reference inputs	Up to 12	Up to 50
3D blockout input	Not supported	Supported
Prompt adherence	Baseline	~20% higher

Same-prompt clips and pricing context live on the 2.5 vs 2.0 comparison.

Use Cases

Which limits matter for your brief

Map the table above to real jobs—ads, multi-character scenes, previsualization, and iterative campaigns.

30-Second Ads in One Pass

A 30-second spot needs an opening hook, a product moment, and a closing frame. Because Seedance 2.5 generates the entire arc in one native pass, product appearance and lighting stay consistent from open to close without manual color-matching between separate clips.

Test This Spec

Multi-Character Scene Production

With 50 reference slots, supply one reference image per character and generate a multi-person scene where every face stays spatially stable and recognizable across the full 30 seconds—something a 12-reference model cannot hold reliably.

Test This Spec

Product & Spatial Previsualization

Supply a 3D blockout mesh to lock camera position and object proportions before spending credits on a final render. That keeps previsualization, architectural flythroughs, and VFX blocking cheap to test and iterate.

Test This Spec

Iterative Campaign Production

Higher prompt adherence and native audio mean fewer full re-rolls per asset. When one element of a clip is wrong, you adjust that element rather than regenerating the whole 30 seconds from scratch—more usable output per credit spent.

Tips

Work the limits harder

Structure prompts in three beats

Split a 30-second brief into setup, action or reveal, and closing frame. Seedance 2.5 follows a structured scene architecture more reliably than one long, unbroken description.

Reference every recurring subject

With 50 reference slots available, there is rarely a reason to describe a recurring character or product from text alone—upload a reference image for anything that needs to look the same twice.

Draft in Fast mode, finish in Standard

Lock composition and motion in Fast mode at 720p or 1080p before spending Standard-mode, 4K-tier credits on the final export.

Combine reference types deliberately

Mix a character image, a motion-reference clip, and an audio bed in one job—each reference type controls a different dimension of the output, which is closer to directing than prompting.

FAQ

Specs FAQ: formats, modes & combinations

What reference file formats are supported?

Images: jpeg, png, webp, bmp, tiff, and gif. Video references: mp4 and mov. Audio references: mp3 and wav. Text prompts are natural language. All reference types can share the same 50-input job.

What is the difference between Fast and Standard mode?

Fast renders quicker at a lower per-second credit cost—best for locking composition, motion, and reference tags. Standard costs more per second and is the mode for a locked brief and final export.

Which aspect ratios are available?

16:9, 9:16, 1:1, and 4:3. Choose before you generate—social-vertical, widescreen, square, and standard all render natively instead of being cropped afterward.

Can I combine a 3D blockout with image references?

Yes. The mesh locks spatial layout and camera position; separate image, video, and audio references (within the 50-input ceiling) control look, style, and sound on the same generation.

How does the reference ceiling compare to Seedance 2.0?

2.0 supports up to 12 references in this tool; 2.5 raises that to 50—enough for multi-character and dense brand-asset briefs. Full comparison: Seedance 2.5 vs 2.0.

Do these capabilities stack in one render?

Yes. One job can use multimodal references, a 3D blockout, native audio, and Standard 4K together—nothing is gated into mutually exclusive modes.
