Introduction¶
Most creators of knowledge-based short videos have used whiteboard animation: a topic is presented, the image is drawn stroke by stroke, and with narration and subtitles added, it can be posted directly to Douyin or WeChat Channels. However, the visual style of whiteboard animation features single-color marker textures, appearing cold and rigid; it lacks high recognizability over long viewing periods. Another common approach online is “colored pencil videos,” which offer warmer colors and a hand-drawn, scholarly vibe. Yet, many finished products suffer from a plastic look, overexposure, blurry lines, simplified secondary characters, and monotonous layouts.
The Skill introduced below transforms the whiteboard animation engine into a colored pencil style specifically to solve the issues found in the two categories above. The illustrations are replaced with a colored pencil texture (soft, multi-colored, visible stroke particles, and paper texture), the cursor is changed from a whiteboard marker to a colored pencil tip, and the visual positioning is defined as “scholarly, warm-toned colored pencil.”
What is This¶
“Colored Pencil Hand-drawn Video (All-in-One Edition)” is a community-sourced Skill located at @user_e0bd737f/caiqian-video. It is categorized under design-media, published by user_e0bd737f, and authored by “Jiajia Youyu.” The current version is 1.4.0.
It solves a singular problem: given a topic (or a single sentence), it generates a short colored pencil hand-drawn video where “the pencil draws stroke by stroke.” It includes Chinese voiceovers and automatic subtitles, with selectable vertical 9:16 or horizontal 16:9 aspect ratios. The final video is ready to be posted directly to Douyin, WeChat Channels, Xiaohongshu, or Bilibili.
It is necessary to clarify the difference from whiteboard animation: the illustrations in whiteboard animation are single-color marker lines with a marker-based cursor; this Skill’s illustrations have a colored pencil texture with a colored pencil tip cursor. It is a different visual style based on the same engine as whiteboard animation, not a replacement.
Core Features¶
Based on the positioning above, the capabilities of this Skill can be broken down into five parts, all sourced from the official description and verifiable item by item.
1. 20 Art Styles. Expanded from the original 6 to 20, covering: Classic Colored Pencil, Gongbi Fine Brushwork, Chinese Xuan Paper Color, Healing Macaron, Morandi High-end Gray, Childlike Crayon, Thick Painting Picture Book, Cyan-Green Landscape, Vintage Print, Collage Paper-cut, Charcoal Sketch, Neon Cyber, Dreamcore Blending, Minimalist Ins, Cinematic Warm Tone, Classical Dark Tone, Impression Garden, Exotic Orient, Dunhuang Heavy Color, and Vintage Film.
2. 14 Color Palettes. Warm Picture Book, Chinese Ink, Morandi, Macaron, Childlike Crayon, Charcoal Grayscale, Cyber Neon, Cyan-Green Landscape, Vintage Set, Cinematic Warm Tone, Classical Dark Tone, Impression Garden, Exotic Orient, and Dunhuang Heavy Color. Styles and palettes can be combined.
3. Painter Inclusion (Optional). The default remains the pen tip cursor; if “companionship” is needed, three character roles can be selected to accompany the drawing: Scholar Painter, Internet-famous Orange Cat, or Cartoon Child.
4. One-Sentence Story Mode. Provide a single sentence, and it automatically expands into a narrative short film with 3-5 scenes, suitable for users who do not want to split the storyboard themselves.
5. Topic × Audience Matrix. Directions listed by the official include Science (Aerospace/Military/Universe/Human Body), Psychology, History, Parenting, and Traditional Culture, positioning it for “all-age bloggers to build vertical accounts without gaps.” The introduction also mentions genres like Fables/Idioms, Children’s Safety Education, Solar Terms/Holidays, Brand/Personal IP Stories, Emotional Healing, and Life Hacks.
Additionally, two content-level constraints are written into the introduction: First, the “Content Three-Part Iron Law”—Real Topics + Hook/Body/Golden Quote, rejecting empty chicken soup, and supporting the replacement of machine voice with personal recordings. Second, “Image Quality Fix”—Heavy dark brown bold outlines (thicker ink), white space around the edges to prevent crowding the subject, and the iron law of light backgrounds. These two rules are the underlying mechanisms it uses to avoid the plastic look, overexposure, and blurry lines.
Installation and Activation¶
First, an honest situation must be disclosed: The retrieved official materials do not contain installation commands, installation directories, or configuration fields that can be directly verified. It is a Skill from a community source in the universal SKILL.md format. The tag only contains requires_api_key=false, meaning no additional API key is required to run it.
Therefore, no unverified commands will be written here. To install and activate, please refer to the official pages:
- Official Address: https://api.skillhub.cn/user_e0bd737f/caiqian-video
- SkillHub Page: https://www.skillhub.cn/skills/user_e0bd737f/caiqian-video
During this writing, I attempted to open the two addresses above to verify them, but both failed to load. Therefore, please refer to the official pages you can access for installation steps; this article will not invent commands to replace them.
Typical Usage¶
The materials do not provide reproducible API call examples or input/output schemas. Below, only the usage methods explicitly stated in the official introduction are described, without adding specific parameters.
-
Give a Topic. State a topic (e.g., a science fact, an idiom story, a life hack), and the Skill will draw it into a colored pencil hand-drawn short video.
-
Select Direction. Choose one or more from the 20 art styles, and one from the 14 color palettes; enable Painter Inclusion for companionship if needed, choosing between Scholar/Orange Cat/Cartoon Child.
-
Define Layout and Aspect Ratio. Choose between vertical 9:16 or horizontal 16:9. The layout is Top Image/Bottom Text (vertical) or Left Image/Right Text (horizontal).
-
One-Sentence Story Mode. If you do not want to split the storyboard yourself, use a single sentence to trigger a 3-5 scene narrative short film.
-
Voiceover. Default is Chinese machine voiceover + automatic subtitles; personal recordings can be used to replace the machine voice.
Use Cases and Considerations¶
Suitable for: Knowledge bloggers who want to build a personal IP or need to turn knowledge into vertical series content. It covers age groups from early childhood education, children’s science, youth workplace psychology, history/culture, to elderly wellness and anti-fraud. Its value lies in unifying “knowledge content” into a recognizable colored pencil visual style, facilitating series and matrix creation.
Unsuitable scenarios: The official definition clearly sets boundaries: No live-action talking head videos, no mixed real-life footage, and no pure animation effects without narration—please use other video skills for these. In other words, what it produces is a “drawn explanation film,” not a live-action video or a pure effects film.
Points to note: First, image quality and layout rely on its set of iron laws (light background, white space, dark brown bold outlines). If the topic inherently requires dark tones or strong contrast, it may conflict with the “light background” rule, requiring personal trade-offs when selecting styles and palettes. Second, it is modified based on the whiteboard animation engine, so the narrative pacing and storyboard logic are consistent with whiteboard animation. If you require cinematic camera language, it cannot provide that.
Conclusion¶
The value of this Skill lies in converging “colored pencil hand-drawn short videos” from a manual task requiring self-adjustment of style, layout, and voiceover into a standardized workflow of “give a topic, select a style, produce a finished video.” The selection space for styles and colors is also much larger than common whiteboard animation. If your knowledge content requires a unified warm-toned colored pencil visual, you can start here.
