Video spreads fast in a breaking story and is easy to miscaption, re-edit, or fake. Verifying it applies the same discipline as image verification, extended across frames — establish provenance, place, and time before you rely on it.
What you'll need
- The video file or a stable link to it
- Reverse image search and media tools from the Photos & Videos category
- Mapping tools from the OSINT Maps category for geolocation
Steps
- Establish provenance first. Find the earliest posting of the video. A clip presented as "breaking" that has circulated for months is debunked immediately — check the account, caption, and date of the first appearance.
- Break it into keyframes. Extract still frames at scene changes and reverse-search them. This finds earlier copies, the original source, and any re-uploads with different claims.
- Geolocate the scene. Treat a representative frame like a photo: read signage, architecture, and terrain, and match them against satellite and street imagery to pin the location.
- Chronolocate the footage. Use shadows, weather, foliage, and visible events, plus any surviving metadata, to establish when it was filmed (see chronolocation).
- Check for manipulation. Look for edits, splices, mismatched audio, impossible physics, and generation artifacts. Be alert to deepfakes — no single automated detector is reliable, so combine cues rather than trusting a verdict.
- Corroborate independently. Does any trustworthy source confirm the event the video claims to show? Only when provenance, place, time, and corroboration align does it meet a publishable standard.
Common pitfalls
- Verifying one frame and stopping. Edits and splices hide between scenes; sample across the whole clip.
- Trusting an "AI detector". Detectors are unreliable; layered human verification is what works.
- Confusing real footage with a false caption. Genuine video is routinely miscaptioned — provenance is the test, not appearance.
Verify your result
You have verified a video when you can state where and when it was filmed, that its current caption matches its origin, and that you found no signs of manipulation — or, if any check fails, you have debunked it. Preserve the frames and your evidence, and state your confidence honestly.
