What problem does it solve?

Writing effective prompts for Seedance 2.0 video generation is hard: vague prompts produce frozen frames, identity drift, and fake-looking motion. This Skill supplies the parameter knowledge and prompt-writing methodology needed to produce coherent, dynamic AI video through TapCanvas's own generation pipeline.

Core Features & Use Cases

  • Three Generation Modes: Documents text-to-video, image-to-video, and reference-to-video inputs, including limits on reference images (0-9), videos (0-3), and audio (0-3).
  • Timeline Beat Prompting: Teaches timestamped beat-by-beat prompt structure with one action per beat, cinematic camera terms, impact physics, and negative prompts to eliminate static-frame artifacts.
  • Consistency Guidance: Explains how to use identity anchor images, storyboard frames, and motion reference videos to keep characters and products consistent across shots.
  • Use Case: When generating an 8-second fight scene clip on the TapCanvas canvas, use this methodology to write a timestamped prompt with per-beat actions, camera moves, and physical consequences, then submit it through the project's own video node.

Quick Start

Ask the agent to write a Seedance 2.0 video prompt for your scene using the timeline beat method and generate it through the TapCanvas video node.

FAQPage Schema
How do I write a Seedance 2.0 prompt that avoids static frozen frames?

Use timeline beat prompting: distribute actions across explicit timestamps like [0s] [1.5s] [3.5s], with one main action verb and one camera move per beat. Describe impact physics and consequences rather than vague verbs, and add negative prompts like avoid jitter and no identity drift.

What are the Seedance 2.0 video generation modes and input limits?

Seedance 2.0 supports text-to-video (prompt only), image-to-video (1-2 images), and reference-to-video (0-9 images, 0-3 videos, 0-3 audio clips). Videos run 4-15 seconds at 480p or 720p with optional synchronized audio.

Does this Skill call the Seedance API directly or need an API key?

No. This Skill only provides methodology; actual generation goes through TapCanvas's own video node and new-api doubao-seedance channel. You must not register external keys, curl external endpoints, or use -face model variants.

How do I keep characters consistent across Seedance video shots?

Derive single anchor images (headshot plus full-body) from the identity board and attach fixed appearance descriptions per shot. Put the character anchor in the first 20-30 words of the prompt, prefer 2 clean reference images over many, and never feed full three-view sheets to the video model.

When should I use reference videos instead of text-only motion descriptions?

Use reference-to-video mode with a 3-8 second clean single-action reference clip for complex fight choreography or realistic weight and follow-through. Seedance transfers the motion path and camera work from the reference while text and images control style and appearance.
