As an Independent AI Contractor, I optimized prompts and performed deep video audits to identify and correct generative model errors. Evaluations focused on logical consistency in AI-generated visuals. The task required detailed review of physical motion and lighting within video outputs. • Conducted comprehensive audits of AI-generated video assets. • Refined model prompts for precise results. • Evaluated and flagged logical inconsistencies ('hallucinations'). • Provided targeted feedback for model enhancement.
