From a media match to an event

A search finds an hour of video labelled "possible unsafe activity". That is a lead, but the reviewer still needs the seconds that support the claim, the surrounding context, and the applicable procedure. A saved description alone cannot provide all of that.

A recording is narrowed to a relevant interval with surrounding context. Video frames, audio, and transcript align with source, time, location, and uncertainty. Generated coaching remains separate from original incident evidence. — **Find the event, then check what happened**Teaching illustration.

Search and verification need different information

An embedding or generated description can help discover a recording. The original clip supports inspection of the event. Retain its source, time interval, scene or asset identity, processing version, and known uncertainty. Do the same for a photograph or audio excerpt.

A transcript helps find spoken words but may omit tone, background sounds, or visual context. Keep it linked to the recording and avoid treating uncertain speaker identity as confirmed.

Build an event record

Attach the relevant interval and enough context before and after it to judge the claim. Distinguish an observation from its interpretation: "person visible near vehicle" and "person violated the exclusion rule" require different support.

This event record can become part of episodic memory. Its images and audio are information forms, while its episodic role is to preserve what happened. That distinction keeps the memory design understandable.

Check before creating an action

For safety coaching, a reviewer should see the evidence and the relevant procedure. Verify identity through the approved process before addressing a person. A generated coaching video is educational output; it must not be filed as footage of the incident.

Test both finding and locating

Measure whether search discovers the right recording and whether it identifies the right interval. Include darkness, occlusion, background noise, unusual scenes, and events that should not trigger a finding. Compare with the existing detector or manual review process.
