unDream AI in Practice: One-Click Storyboard-Driven Video Generation with Agent + Skill

The Efficiency Bottleneck Between Storyboard and Final Cut

For AI video creators, the biggest pain point is rarely about model capability — it's the near-impossible balance between coherence and efficiency. Traditional storyboard-to-video workflows require adjusting every single shot and timestamp one by one, making the process extremely costly. Yet going straight from a "scene + character + prompt" approach often results in poor quality, visual glitches, jarring cuts, and broken continuity between frames.

As shared by a Bilibili creator through hands-on testing, these problems become especially pronounced in long takes or multi-shot narrative sequences. After trying a wide range of methods to address this contradiction, the author eventually landed on a highly efficient, coherent approach — driving video generation directly from a Storyboard. The key insight is that this storyboard isn't assembled through brute-force prompt stacking — it's produced through a combination of Agent + Skill.

Understanding the Core Relationship Between Agent and Skill

To make the most of this workflow, you first need to understand two core concepts.

Agent: Your Virtual Creative Employee

After creating a new project in unDream, there's a conversation panel on the far right of the canvas — this is what's commonly referred to as the Agent. Think of the Agent as a "virtual employee" — you can ask it to write text, generate image prompts, or carry out all kinds of creative tasks.

The catch is that an Agent in its initial state is essentially a blank slate with no specialized skills. Giving it complex instructions right away tends to yield underwhelming results, simply because it lacks domain-specific expertise.

Skill: Installing Professional Capabilities into Your Agent

The solution is to "install skills" into this virtual employee — that's what Skills are for. The "Skill Community" in the bottom-right corner of the canvas offers a rich library of preset skills.

The core value of these skills lies in the fact that they've already been tuned and refined. Each Skill comes with a built-in reasoning framework, reference points, and specific output formats. In other words, you don't need to craft complex prompts from scratch — the professional workflow is already packaged inside the skill, ready to use out of the box.

Activating the "Expert Director Storyboard" Skill

This demonstration uses a Skill called "Expert Director Storyboard." Here's how to activate it:

1. In the Skill Community, hover over the prompts and locate "Expert Director Storyboard"
2. Click to view the skill description and sample output
3. Be sure to click "Activate Skill" (this step is critical — activation is required before the skill can be quickly invoked anywhere on the canvas)
4. Select "Use Now"

Once activated, right-click anywhere on the canvas, open the "Plugin Library," and you can find and invoke this skill directly. The storyboard-specialized Agent will then appear on your canvas, ready for interactive conversation.

Hands-On Demo: From Reference Image to Storyboard

After invoking the skill, a storyboard prompt panel pops up on the right side. The author's workflow looked like this:

• Clear the default content in the prompt panel
• Drop in a reference image
• Enter a brief description, such as "generate a storyboard for a special effects fight sequence"

The Agent offers two execution modes: "Ask" and "Auto". Choosing "Auto" lets the AI make all decisions independently; choosing "Ask" prompts the Agent to check in with you at key decision points. The author chose "Ask" mode for this demo — during the process, the Agent posed two key questions: What's the setting? (A mountaintop in the snow) What's the opponent? (A giant demon beast).

Pro tip: If you already have a clear scene and character setup from the start, include those details directly in your initial request to skip the back-and-forth.

Decoding the Arrow Notation in the Storyboard

The generated storyboard includes red arrows and blue arrows — a professional visual language built into the Skill's prompt template:

• Red arrows: Indicate the direction and movement trajectory of the camera
• Blue arrows: Indicate the movement trajectory of characters or objects

This visual annotation system makes the motion logic of each shot immediately clear. It's a direct expression of "director thinking" baked into the Skill, and it's precisely what sets this AI storyboard workflow apart from ordinary prompt-based image generation.

Style Refinement and Final Video Generation

The initial storyboard is produced as a rough sketch, so further style refinement is needed. Select the storyboard, then enter your style requirements in the input field below — for example, "convert the storyboard into a full-color realistic style." The style is entirely up to you — write "photorealistic" for a live-action look, or "ink wash painting" for a traditional Chinese art aesthetic. The flexibility here is exceptional.

Critical Prompt Detail for Video Generation (Avoid This Pitfall)

The final step is feeding the refined images into video generation. The author specifically highlighted one extremely easy-to-miss detail: the video generation prompt must include instructions to remove all visual guide markers, for example:

The final video output should automatically remove all red camera motion arrows, blue object motion arrows, shot annotation text, and guide lines — retaining only the original scene, characters, and creature effects.

If you omit this, the generated video will literally have arrows and annotations baked into the footage, severely degrading the final output quality. Once everything is set, choose an appropriate model tier (the demo uses C-tier 12.0) and click generate.

Workflow Summary and Creative Extensions

The core logic of the entire process can be summarized as:

Blank Agent → Activate Professional Skill → Input requirements to generate storyboard → Style refinement → Remove annotations → Generate video

The real value of this approach isn't any single storyboard skill in particular — it's the Agent + Skill combination paradigm itself. The Skill Community contains a wide array of pre-tuned professional skills, meaning creators don't need to become prompt engineering experts to tap into powerful, specialized capabilities.

For creators who want to improve the coherence of their AI videos without getting bogged down in frame-by-frame adjustments, this is a viable path that balances both efficiency and quality — and the Skill Community holds even more possibilities waiting to be explored.
