Knowledge-Intensive Video Generation
Summary
Knowledge-Intensive Video Generation (KIVI) is introduced as a new paradigm where models create videos from short information-seeking prompts, such as requests for explanations, procedures, or demonstrations. This approach addresses the current under-evaluation of text-to-video generation models regarding factuality and practical usefulness. To facilitate evaluation, KIVI-Bench, a benchmark comprising 1,080 prompts, was constructed. The research also proposes automatic metrics designed to assess factuality and helpfulness, which human evaluations confirm align significantly better with human annotations than existing alternatives. Experiments conducted on seven advanced video generation models reveal that current systems perform below human levels, particularly struggling with visual properties, procedural operations, and clear information presentation. This highlights KIVI as a challenging new direction for developing factual and instructionally useful video generation capabilities.
Key takeaway
For AI Scientists and Computer Vision Engineers focused on advancing text-to-video generation, this research indicates a critical need to shift focus beyond visual quality to factuality and instructional utility. You should prioritize developing models that accurately represent information, execute procedural operations correctly, and present content clearly. This will address current system limitations identified by KIVI-Bench and move towards truly useful knowledge-intensive video generation.
