SkillPE: Creativity-Oriented Cinematic Skill Evolution for Text-to-Video Prompt Engineering

2026-09-28

AI Summary

This study addresses the challenge faced by non-expert users in generating high-quality cinematic videos that balance professional storytelling with creativity. To this end, it proposes a prompt optimization framework grounded in a reusable cinematic skill library. Methodologically, the approach pioneers the evolution of cinematic skills from expert seeds, integrating resonance, incongruity, and divergent reference strategies to balance fidelity and creativity, while leveraging divergent near-miss cases to stimulate alternative ideas. Technically, it introduces fine-grained cinematic cue representations and a multi-category retrieval-augmented generation mechanism. Experimental results demonstrate that the proposed method outperforms the strongest baseline by 1.40 points on StoryEval and VBench, significantly surpassing seed skills, and establishes a comprehensive four-dimensional evaluation framework.

Abstract

Achieving high-quality, cinematic results in text-to-video generation remains challenging for non-experts, whose prompts often lack professional narrative and creative design. We propose SkillPE, a prompt engineering (PE) framework that evolves reusable cinematic skills from expert-authored seeds. SkillPE represents shot logic, composition, lighting, sound design, and other filmmaking cues in a fine-grained format, and retrieves movie references categorized as resonators (good matches), dissonants (weak matches), and divergents (creatively useful near-misses). The first two refine when and how a skill should be applied, while divergents inspire alternative cinematic realizations at different degrees of modification while preserving the user intent. Candidate skills are assessed through generated videos along prompt fidelity, cinematic quality, narrative appeal, and creativity to construct the final skill libraries. Experiments on StoryEval and VBench show improvements of up to 1.40 points over the strongest external baseline and 0.51 points over seed skills on 7-point four-dimensional evaluation, while remaining competitive on benchmark-native metrics. Overall, SkillPE offers a practical approach to balancing fidelity and creativity in cinematic text-to-video generation. Code is available at https://github.com/Ais0n/SkillPE .
