# BVB: Benchmarking Agentic Video Understanding via Programmatic Reconstruction in Blender > Source: > Published: 2026-09-15 02:30:00+00:00 Multimodal agents can create complex videos in software such as Blender by coding without relying on diffusion models. Yet video understanding benchmarks still evaluate models mainly through question answering. If an agent truly understands a video, it can reconstruct it programmatically. We introdu
