AI video generators can now spit out footage in seconds that would've fooled anyone two years ago — and it's all over your feed. The good news? Most AI clips still leave fingerprints. Here's a quick routine for vetting a video before you believe it, or worse, share it.
Start with the hands
Hands are still AI's most reliable failure point. Fingers move, grip and overlap in ways generators struggle to fake. So count the fingers. Watch how hands hold objects. Look for stiff, puppet-like motion, odd shapes, fingers that merge and split between frames. One weird hand outweighs a hundred convincing pixels.
Then the face
Real faces are imperfect and busy. AI faces run eerily smooth — strange eye behavior, missing micro-expressions, symmetry that's a touch too perfect. Watch the eyes: blinking that's metronome-regular, or a gaze that never quite lands on anything.
Then the mouth. Perfect lip-sync is hard to fake. Look for lips drifting out of step with the words, especially mid-sentence.
Listen without watching
Now close your eyes and replay it. AI voices tend to have unnatural pacing — no hesitations, no audible breathing, flawless pronunciation start to finish. Many sound faintly rushed, all the time. Real people stumble and pause and breathe. A voice that never does? Be suspicious.
Check the light
Lighting bugs survive even in polished fakes. Shadows that flicker only on the speaker's face, or only in the background — real physics doesn't do that. Warping backgrounds, smeared textures, objects that quietly change shape between frames: classic tells, all of them.
Apply the logic test
This is the check that outlasts every technical fix. AI nails the visuals but often botches the logic — the relationships between timing, place and circumstance. With breaking-news footage, trust what you know about the world. Does the weather fit the season? Does the crowd fit the event? Would a camera even have been there?
Experts spot this instantly on their own turf — climbing ropes rigged unsafely, uniforms slightly off. You have a domain you know cold, too. Use it.
Verify the source
Before you share, give provenance thirty seconds. Who posted it? Does the account have a history, or did it appear last month? Are reputable outlets running the same footage? A dramatic clip that exists in exactly one place is a red flag — however real it looks.
The habit that matters most
Every trick above will age; generators improve monthly. What lasts is the habit: don't automatically believe what you see online. If it feels unreal, it probably is. And if a video hands you a sudden hit of outrage or vindication — that's exactly the moment to slow down and check.
Ten seconds of skepticism is free. Sharing a fake costs your credibility.
