That video "from today" may be months old: how recycled clips fool people on social media

It happens every time something big occurs. An earthquake, a flood, a blackout or a protest, and within minutes WhatsApp groups and social feeds fill up with "live" videos. Many are real. But a surprising share are old recordings, from another place or another year, that someone re-uploads with a new caption. Fact-checkers have just debunked another example: a video filmed in Buenos Aires in June that circulated this week as if it showed a recent event in another country.

You don't need artificial intelligence to mislead people: taking a video out of context is enough. That's why this kind of misinformation is so common, and why it's worth knowing how to recognize it.

Why videos get recycled

• To gain followers: accounts that are first to post "the image of the moment" rack up views and followers they later monetize or sell.
• By mistake: plenty of people forward what a relative sent them in good faith, convinced it's current.
• To manipulate: a violent video from another country can be used to exaggerate a local protest or blame a particular group.
• To scam: some disaster clips are paired with fake donation campaigns.

The telltale signs

1. The weather and clothing don't fit

If it's winter where you live and the people in the video are in T-shirts, or trees are blooming out of season, be suspicious. It's one of the simplest and most effective clues.

2. Signs, license plates and accents

Pause the video and read what's visible: shop names, road signs, license plates, a TV channel's logo. Listen to accents and word choices. Often the video itself tells you where it was filmed.

3. Odd quality and format

A heavily pixelated image, cropped watermarks or another platform's logo usually mean the video has been downloaded and re-uploaded many times.

4. No source confirms it

If something that dramatic had really happened, local media and authorities would be reporting it. If it only appears in chain messages and anonymous accounts, wait.

How to check it in two minutes

1. Take a screenshot of a clear frame from the video.
2. Search it with Google Lens, TinEye or Yandex Images. If the video existed before the event it supposedly shows, it will turn up with earlier dates.
3. Use tools like InVID-WeVerify, a free browser extension that pulls key frames from a video and makes searching easier.
4. Search keywords on X, TikTok or YouTube along with "fake" or "fact check", or on fact-checking sites in your country.
5. Verify the location with Google Maps or Street View: sometimes comparing a single building or street corner is enough.

The most common case: earthquakes

After the recent quakes in the region, footage from earthquakes in Mexico in 2017, Turkey in 2023 and Japan in 2011 resurfaced, presented as if it were from that day. In frightening moments, this content spreads more panic and can flood emergency services with false information. In those situations, the most useful thing is to follow only official civil protection channels and established news outlets.

What if I've already shared it?

It happens to everyone. The best thing to do is delete it and, if you sent it to a group, add a short message: "The video I shared is old and from somewhere else; here's the fact check." Correcting yourself publicly isn't embarrassing; it helps break the chain. Research on misinformation shows that corrections from people we know are more effective than corrections from strangers.

What the platforms do

Facebook and Instagram work with independent fact-checkers who can label content as "false" or "missing context" and reduce its reach. X uses Community Notes, where users themselves add context. TikTok and YouTube also remove or label misleading content about emergencies. Even so, no system catches everything in time: users are the first line of defense.

One small habit that changes everything

The golden rule is simple: before you share, ask yourself when and where it was filmed. If you can't answer, don't send it yet. That one second of doubt protects your family and friends and, in a real emergency, can help the right information reach the people who need it.
