Researchers have introduced EntityBench, a new benchmark designed to evaluate the consistency of characters, objects, and locations in long-range, multi-shot video generation. The benchmark comprises 140 episodes with up to 50 shots each, tracking numerous entities across extended recurrence gaps. To address the challenge of maintaining entity consistency, the paper also proposes EntityMem, a memory-augmented generation system that stores verified entity references to improve character fidelity.
