How to tell if a video is real or fake
Find the earliest upload
Most misleading videos are real footage with a false caption, often an old clip from another event. Search the claim, the location and key phrases on several platforms and sort by oldest. Fact-checkers report finding clips that predate the event they supposedly show by days or years.
Search by keyframes, not the whole video
Reverse search works on images, so pull still frames from the video and search each one. The free InVID-WeVerify plugin extracts keyframes and sends them to Google, Bing, Yandex and TinEye. Full Fact's guide suggests trying more than one engine, since results differ.
Searching in other languages can surface debunks an English search misses. And a brand-new video will return nothing, which does not prove it is genuine.
Check that the scene fits the claim
Compare what you can see with what is claimed: signs and language, vehicles, uniforms, shop fronts, skyline, weather, shadows and time of day. Match them against maps and other footage from that place and date. For news events, check whether established outlets or local reporters have published the same footage and where they got it.
Watch for edits and synthetic video
Deepfakes and fully generated clips can show lip movement that drifts from the audio, flickering around the face or hairline, objects that change shape between frames and hands or text that warp. These tells are getting rarer. Cuts that remove context matter just as much: ask what happened before and after the clip.
Metadata can help but is not reliable, since it is often stripped on upload and can be edited.
Look for Content Credentials
If the file carries Content Credentials, the Verify tool shows who signed it and what tool made or edited it. Many videos have none, and platforms can remove them, so treat them as a bonus when present, not a requirement.
How Emera handles this
Every post on Emera carries a signed record (C2PA content credentials) of who shared it and when it went up. A Signed badge says exactly what was checked and nothing more. Reposts point back to the original post, so you can see who shared a clip first. Emera does not fact-check videos or promise that anything is real.
People also ask
Can I trust a video because many people shared it?
No. Sharing counts say how popular a clip is, not whether it is genuine. Many viral clips are old footage with new captions.
How do I spot a deepfake?
Check the source first, then look for mismatched lip movement, flicker near the face, warped hands or text and odd lighting. None of these is conclusive, and good fakes avoid them.
What if my reverse search finds nothing?
That means no earlier copy was indexed, not that the video is real. Keep checking the source, location and other reporting.
Is there a tool that gives a yes or no?
Not one you should rely on. Detection tools give estimates and are wrong in both directions.
