AI Visual and Motion Design Techniques (Prompts and Tools for Upscaling & Sharpening Images / 3D Icon & IP Design / KV Key Visuals / Stylized Illustrations / Visual Remix Reconstruction)
Highlights from Will’s practical notes on AI visual generation: breaking down "using AI to produce visual assets" into 6 actionable task categories, each with reusable prompt skeletons, rationales, and common pitfalls. ① Image enhancement (turning blurry portraits into 4K / sharpening general images): relies on image-to-image detail reconstruction via Gemica/Gemini; the key constraint is "lock identity and composition, only fill in details, do not add new elements"; for portraits, use camera parameters (85mm f/1.4 / Sony A1) to force photorealism. ② 3D icons & IP design: AI has extremely strong recognition of 3D textures, so finding reference images > writing prompts (50% time spent finding images + 50% debugging); provides ready-made prompt templates for Airbnb isometric icons, soft vinyl blind box figures (Kakao Friends style), Apple skeuomorphic icons, and highly stylized 3D avatars. ③ KV key visuals: two approaches — "reskinning" (replacing the IP on a mature reference image, adjusting poses/environment to avoid plagiarism) and "original creation" (hand-drawn line art + AI stylization), including pitfalls such as using a 1:1 head-to-body ratio to prevent AI from switching to realistic human proportions. ④ Stylized illustrations & state graphics: one sentence to make AI produce a set of 6 stylistically consistent onboarding illustrations (lock color palette and brushwork, loosen shape constraints). ⑤ Visual remix reconstruction: take one dimension from each of multiple images (shape from image 1 + texture from image 2 + lighting from image 3) and fuse them into a custom visual, including a 4-step iterative practical case for in-car HMI. ⑥ Visual reference dimensions: 6 "image breakdown checklists" for photography/illustration/3D/brand/character/product photography, teaching PMs to break a reference image down into describable keyword dimensions. Target readers: PMs building AI products who need to produce icons/KVs/illustrations themselves; industry jargon is explained in-line, and prompts are retained in both Chinese and English.
