Seedance 3 | Cinematic AI Video Generator

Seedance 3 is a web-based AI video generator that produces short, motion-rich clips from text prompts, key frames, or source images, with a focus on shot continuity and camera direction.

What is Seedance 3?

Seedance 3 is a prompt-first video tool that converts text descriptions, reference images, and camera instructions into 4‑second, 480p, 1:1 aspect ratio video clips (with audio). It runs entirely in the browser at seedance-3.pro, using ByteDance’s Seedance 1.5 Pro model under the hood. The product is designed for teams who need tighter motion direction than typical text-to-video tools offer, with less setup before the first render.

Key Features

• Text-to-video briefs — Describe scene intent, camera movement, and tone in a single prompt field (2,000 character limit).
• Image-to-video starts — Anchor the opening frame with a source image to stabilize subject identity before generating motion.
• Camera and motion prompting — Guide pacing, shot size, and motion path through structured prompt syntax, without needing separate camera controls.
• Reference-aware iteration — Keep motion direction steady while testing alternate outputs; adjust prompt details without restarting from scratch.
• Short-form campaign drafts — Produce launch visuals, social media clips, and concept reels at 4‑second duration, ideal for quick review loops.
• Public blog and update log — The site ships with a blog and updates page to document prompt patterns and product changes (see blog and updates).

Who is it for?

• Short-form video teams — Social media managers and content creators who need campaign‑ready clips with consistent motion, not raw AI hallucinations.
• Concept artists and storyboarders — Those who want to rough out shot options and camera moves before committing to full production.
• Marketing and launch teams — Users building teaser visuals, social ads, or product reels that require tighter shot continuity than generic text-to-video tools provide.

What can you do with Seedance 3?

• Generate a launch visual from text — Write a 30‑word scene description with camera direction, and get a 4‑second clip with matched motion.
• Iterate on a key frame — Upload a still image as the first frame, then prompt the tool to extend it into a short video while preserving the subject and composition.
• Test motion directions quickly — Compare multiple prompt variations by changing only the camera or motion path, without regenerating the full scene.

How does it work?

The workflow is a four‑step loop: first, define the scene with a text prompt (up to 2,000 characters); second, optionally upload a key frame or source image to lock in identity and composition; third, guide the camera with motion‑specific language in the prompt; fourth, generate and review the 4‑second, 480p, 1:1 clip (costs 7 credits per generation). Iterate by adjusting the prompt or key frame until the motion matches the desired pace.

FAQ

Can I start from prompts only?

Yes. Seedance 3 supports pure text-to-video generation. A prompt is all that is required; key frames and camera instructions are optional enhancements for finer motion control.

Is Seedance 3 free?

Seedance 3 uses a freemium model. Each generation costs 7 credits, and the free tier provides an initial credit balance (exact number not published). Paid credit packs are available for heavier use.

What output specs does Seedance 3 produce?

All clips are 4 seconds long at 480p resolution with a 1:1 square aspect ratio and audio. Longer durations and higher resolutions are not available in the current public surface.

Do I need to sign in to use the public surface?

The product website, blog, and update log are publicly accessible without sign-in. Generating videos requires an account and credits.
