Researchers have developed VERTIGO, a novel framework designed to enhance the quality of AI-generated cinematic camera trajectories. This system utilizes a real-time graphics engine to render previews of generated camera motions, which are then scored by a fine-tuned vision-language model. The scoring process employs a cyclic semantic similarity mechanism to align renders with text prompts, providing visual preference signals for Direct Preference Optimization. VERTIGO has demonstrated significant improvements, reducing off-screen character rates from 38% to nearly 0% and achieving higher user preference for composition, consistency, and aesthetic quality.
