A viral video is not one question. Ask: where was it filmed, when, is this the original file, and can I publish it?

Find the earliest known upload. Later shares are lineage, not confirmation.

Landmarks, weather, shadows, and independent local footage can support place. A caption cannot.

Upload time is weak date evidence. Old footage is routinely recaptioned as today.

If you cannot place or date it, the correct output is INSUFFICIENT EVIDENCE. That is not failure.

Missing EXIF or C2PA does not mean fake. An AI detector score is an indicator, not a verdict.
