Combining the visual systems of many renowned directors including Nolan, Wes Anderson, Zhang Yimou, Wong Kar-wai and Tarkovsky, the lecture was supported by complete practical cases of original short films. It explained practical skills covering the whole chain from style templates, asset construction, shot transitions to post-production adaptation, covering multiple creation tracks such as cultural tourism promotion, commercial advertisements, original animations and documentary short films. It helped trainees eliminate core pain points like inconsistent styles, distorted frames and unnatural shot transitions in AI creation.

I. Analysis of Classic Directors’ Visual Styles & Reusable AI Prompt Templates

The core module of Teacher Zheng Xu’s lecture focused on the visual language of mainstream directors. He systematically disassembled five major creative variables including light and shadow, color, composition, space and camera logic, and summarized standardized, reusable prompt templates, allowing trainees to quickly replicate the visual texture of mature films as needed.

Nolan’s Realistic Sci-fi System: Centered on the core case Inception, its iconic features include real physical light sources, low-saturation high-contrast tones and oppressive large-scale spaces. It contains three layers of creation logic: grand space structure, interlaced time-space narration and distorted physical space. Matching prompts can add keywords such as central composition, space reversal and multi-layer time-space superposition, which are suitable for suspense and sci-fi short films.

Wes Anderson’s Aesthetics: Regarded as a benchmark of symmetrical visual creation, its core lies in extreme symmetrical composition, flattened space, highly controlled colors, mechanical scheduling and emotion-driven plots. Most frames adopt subtle changes within symmetry matched with retro low-saturation macaron tones and horizontal panning shots, suitable for healing and fantasy literary animation short films.

Zhang Yimou’s Diverse Visual System consists of three stages: Early rural documentary style with low-saturation earth tones, natural light and handheld documentary composition where characters are submerged by the environment; mid-stage extreme monochromatic ritual aesthetics with single dominant colors like red, gold and blue matched with symmetrical stage composition turning characters into visual symbols; ink wash oriental imagery based on black, white and gray with light colors, matte light-absorbing materials and large blank spaces full of oriental artistic conception, fit for martial arts and Chinese-style short films.

Wong Kar-wai’s Emotional Imagery: A mix of high-saturation neon lights and dark shadows with strong contrasting colors. He is good at using multi-layer foreground window and door frames to enrich frame layers, damp night scenes, rapid camera pushes and cuts to express extreme emotions, suitable for urban emotional and literary short films.

Tarkovsky’s Philosophical Imagery: Low-saturation blue-gray ruined spaces with abundant natural five-element imagery of water, wind, earth and fire. Slow long shots are adopted for tranquil, profound narration, fit for humanistic and philosophical documentary short films.

In addition to the above classic styles, Teacher Zheng Xu also shared high-saturation stage drama visual templates with rich colors and strong dramatic tension, which can be extended to oriental myth and fantasy advertising short films. All styles were compared with positive and negative cases, and keywords of material, light and saturation were provided to avoid distorted frames such as plastic texture and messy light and shadow generated by AI.

II. Standard Practical Teaching of Full-process AIGC Short Films

Combining the complete landing case of his original integrated short film, Teacher Zheng Xu fully explained the whole industrial process from pre-planning, construction of character and scene assets, storyboard prompt design, segmented video generation to poster production.

(1) Standard Construction of Pre-production Assets to Avoid Character Distortion & Confused Images

Teacher Zheng Xu emphasized that unified complete assets are the foundation of consistent short film styles. Before creation, full three-view character sheets need to be finished, with exclusive costumes, hairstyles and accessories matched for different plot scenes; full sets of scene assets including wide shots, medium shots and close-ups as well as supporting props should be built simultaneously.

To solve the censorship problem of real human portraits, Teacher Zheng Xu shared practical skills: if well-known characters are required in the plot, do not generate real human figures directly; instead, integrate them into frames in the form of murals or magazine illustrations to greatly improve the passing rate of materials.

(2) Standards for Storyboard & Video Prompts, Shot Transitions

Duration Control Standard: A single video segment should be controlled within 15 seconds. Segments of the same scene can be generated continuously, while different scenes need to be produced separately to reduce the risk of frame distortion.

Context-linked Prompt Logic: When writing prompts for a single shot, the transition information at the end of the previous segment must be connected, with clear marks of camera track and space shuttle mode to ensure smooth segment connection. The last frame of the previous shot can be intercepted as the reference image for the next segment.

Standard Prompt Structure: Camera movement + character performance + scene atmosphere + exclusive visual style. Atmospheric elements such as water mist, light spots and five-element imagery can be added as needed to enrich frame layers.

Diversified Transition Solutions: Low-cost AI transitions such as water drops, mirrors, tunnels, ink diffusion and space folding can be realized directly via prompts without complicated post-editing.

（三）多赛道商业创作落地案例分享

(3) Sharing of Commercial Creation Cases for Multiple Tracks

Cultural Tourism Track: AI short films serve as low-cost promotion solutions for scenic spots. Short films created based on regional folk customs and unique scenery can bring stable commercial cooperation and advertising revenue.

Documentary Track: AI can restore scenes that are hard to shoot on-site, suitable for humanistic documentary themes. Multilingual dubbing is available. Dialects without written characters can be dubbed based on standard Mandarin texts. The length of lines needs to be reasonably controlled to avoid stiff character performance.

Chinese Style, Two-dimensional & Stop-motion Animation: Do not rely solely on text descriptions. Input reference images of corresponding styles into the model to greatly reduce the risk of inconsistent painting styles.

（四）配套工具实操指南

(4) Practical Guide to Supporting Tools

Image Tools: Midjourney is suitable for early concept and character art design. Node-based AI video platforms excel in mass production of storyboards and dynamic short films, supporting one-click generation of multi-angle frame materials via nine-grid function.

Post-production Software: The new version of PS AI redrawing and selection tools can quickly fix facial and scene defects, and manually adjust frame proportions and material texture.

Audio Standard: Add restrictive prompts of "no auto-generated background music" when generating videos. Match AI-produced soundtracks and layered sound effects in post-production to avoid conflicts between built-in music and film tone.

III. Short Film Finishing & Derivative Poster Production

Teacher Zheng Xu fully explained the post-editing and audio-video synchronization process of short films, and shared standardized AI film poster creation ideas. Taking director-themed posters as an example, he adopted central axis symmetrical composition, arranged recognizable faces of multiple directors in layers with alternating black, white and light overlapping colors. High-quality film promotional materials can be quickly generated with layered text prompts.

Teacher Zheng Xu provided a reference of creation cycle: After completing standardized asset construction for an original short film, all dynamic materials can be generated within two days, greatly cutting time cost.

Breaking the single software teaching mode, this lecture formed a complete creation chain of "director aesthetic reference — AI asset design — dynamic storyboard generation — commercial landing", catering to both beginner trainees and commercial creators.

Teacher Zheng Xu provided a full set of reusable director-style prompts, storywriting templates and asset construction specifications, targeting common industry problems including inconsistent styles, distorted characters, unnatural shot transitions and commercial material compliance. Trainees are able to independently complete the full industrial creation of cultural tourism advertisements, original animations, documentaries and competition short films.
