Can I tell if a video is AI just by looking at it?

Sometimes, if it has obvious errors in hands, text or physics. But newer models make fewer of these mistakes, so a clean-looking video can still be generated, and a real video can have artefacts from compression.

Are AI video detectors accurate?

Not reliably. They miss output from newer models and sometimes flag real footage, so use them only as a hint alongside source checks.

Does Retrace detect AI-generated videos?

No. Retrace finds the pages where the same footage appears, which helps you check whether the video has a credible original or existed before AI video tools.

What are Content Credentials?

A signed record, based on the C2PA standard, that some tools and cameras attach to a file to describe how it was made or edited. It is often removed when a video is re-uploaded, so its absence proves nothing.

If a video has no AI label, is it real?

Not necessarily. Labels depend on the uploader disclosing it or on metadata surviving the upload, and many generated videos have neither.

Is this video AI?A practical checklist

There is no single test that tells you whether a video is AI generated. What works is a set of checks that each add or remove confidence: what the image itself shows, who posted it, whether a platform or the file says anything about how it was made, and whether the same footage exists somewhere you can trust.

The visual tells are the part everyone talks about, and they are the weakest part. The strongest evidence usually comes from the source: real footage of a real event tends to leave a trail, and generated footage usually has none.

Look for visual tells, but don't treat them as proof

Watch the video more than once, at full screen, and pause on frames where something moves fast or crosses something else. Generators still slip in places like these:

—Hands and fingers: extra or merging fingers, hands that pass through objects, grips that change between frames.
—Text: signs, labels, licence plates and screens with letters that look plausible but don't spell anything, or that change as the camera moves.
—Physics: liquids, hair, cloth and smoke that move wrong; objects that float, bounce oddly or ignore weight; footsteps that don't match the ground.
—Background objects: people, cars or furniture that appear, vanish or morph into something else when they leave and re-enter the frame.
—Lighting: shadows pointing in different directions, reflections that don't match the scene, faces lit from a source that isn't there.
—Lip sync and faces: mouths that don't quite match the words, teeth that blur into one shape, skin that looks too smooth, blinking that feels off.

These tells are getting rarer with every new model. Finding one is a good reason to dig further; not finding any proves nothing. Heavy compression, filters and low light can also produce artefacts in real footage.

If you want to look at specific frames carefully, it helps to extract stills from the video and zoom in, instead of pausing a moving player.

Check the source and the context

Before you study pixels, ask who is showing you this video and why. Most misleading videos fall apart at this step.

1.Open the account that posted it. Does it have a history of normal posts, or was it created recently and only posts viral clips?
2.Look for an original upload. Reposts often crop out watermarks, captions and usernames that would tell you where the clip came from. A credit in the caption or a visible handle is a lead to follow.
3.Read the comments. People who were there, or who found the original, often say so.
4.If the video claims to show news, check whether any established outlet, local authority or eyewitness reports the same event. A dramatic event with exactly one video and no other trace is a warning sign.
5.Check whether the account says the clip is AI, satire or a creative project. Many generated videos are labelled honestly at the source and lose that context as they get reposted.

If the clip is presented as someone you know, or as a person asking you for money, treat it the way you'd treat any scam video: verify through a separate channel before acting.

Check platform labels and Content Credentials

Major platforms such as YouTube, TikTok, Instagram and Facebook show AI or altered-content labels on some posts. These labels usually appear when the uploader discloses it or when the file carries metadata the platform recognises. A label is useful information; the absence of a label tells you very little, because many generated videos are uploaded without disclosure.

Some AI tools, cameras and editing apps attach Content Credentials, a signed record based on the C2PA standard that can describe how a file was created or edited. You can upload a file to the Content Credentials verify tool to see whether it carries one.

Credentials are often stripped when a video is re-encoded, screen-recorded or re-uploaded to social media. If none are found, that does not mean the video is real or fake; it only means the file carries no readable record.

Trace the footage: the strongest check you can do

If the same footage existed online years ago, before realistic video generators were publicly available, it was not made with one of them. If it appears on a credible outlet or an official account with a clear origin, that is also strong evidence. On the other hand, if a clip that claims to be news has no source anywhere and only circulates as reposts, be suspicious.

1.Take a few clear frames from different moments of the video (a screenshot works too).
2.Search them with Google Lens, TinEye or Yandex Images to find pages that show the same images.
3.Use a reverse video search such as Retrace, which samples distinctive frames across the whole clip and lists the pages where the same footage appears. Uploading the file covers the whole video; a link only covers the first few seconds.
4.Open the pages you find and compare their dates, captions and accounts yourself. Look for the oldest credible copy and see how it was described there.
5.If you find a likely original, check archive.org for older snapshots of that page if the date matters.

Retrace does not detect AI. It doesn't analyse whether pixels were generated; it finds where else the footage appears, which is what lets you judge the source. It only sees public pages that search engines have indexed, so private accounts and deleted posts won't show up. For the full method, see how to verify a video and how to check if a video is old.

What about AI detector tools?

Tools that claim to tell you whether a video is AI generated exist, and some newsrooms use them as one input among many. They are not reliable on their own: they produce false positives on real, compressed footage and false negatives on output from newer models, and a percentage score can look far more certain than it is.

If you use one, treat the result like a visual tell: a reason to look further, never the final answer. The free InVID-WeVerify browser plugin, used by fact-checkers, is a better starting point because it bundles keyframe extraction, reverse image search and metadata checks rather than giving you a single verdict.

Putting it together

—Likely real: the footage appears on a credible source, or existed online long before realistic generators, and the context matches.
—Likely generated: a label or Content Credentials say so, the source says so, or several strong visual tells line up with no traceable origin.
—Unknown: no tells, no label, no source. Say you don't know, and don't share it as fact.
