Video Deepfake Detector — Real Footage or Face Swap?
Upload a clip and the video deepfake detector checks the faces in it for swaps, lip sync and AI edits.
For the best result
- Upload the original file, not a screen recording
- Keep the face visible and turned to the camera
- Trim to the part where the person is on screen
What is a deepfake video?
A deepfake video is footage in which a real person's face or lip movements have been replaced or altered with AI, so they appear to say or do something they never did.
Video deepfakes used to need hours of footage and a powerful computer. Now a few minutes of someone's clips and a consumer app can produce a convincing video, or even a live face swap on a video call.
How a video deepfake is made
Collect footage
Clips of the target's face from interviews, social posts or calls.
Teach a face model
AI learns how that face looks from every angle and in every light.
Swap it frame by frame
The face, or just the mouth, is replaced in every frame of the video.
Blend and add a voice
Edges are smoothed and a real or cloned voice is laid on top.
Types of video deepfakes
Not every fake video fakes the same thing. Knowing which part is fake tells you whether the video deepfake detector is the right check.
| Type | What's fake | What catches it |
|---|---|---|
| Face swap video | The whole face is replaced | Face score on this page |
| Lip-sync deepfake | Only the mouth is changed to match new words | Face score on this page |
| Puppet video | A real face is driven by someone else's movements | Face score on this page |
| Fully AI-generated video | Every frame is made by a model like Sora or Veo | AI Video Detector |
| Voice clone over real footage | The voice, not the face | AI Voice Detector |
How does a deepfake detector for videos work?
Upload a clip
MP4, MOV, WebM and most other formats, up to 100MB. Short clips with a clear face work best.
Faces are checked across the clip
The video deepfake detector looks at the faces through the clip for signs of swapping, re-animation or AI editing.
Get one score for the clip
You get one face score for the whole clip. Video results don't draw boxes on individual faces.
Reading the clip score
0–39
No sign of face manipulation
No signs of a face swap. The video can still be AI-generated or edited in other ways.
40–69
Unclear
Some signs, not enough to call. Try the original upload or a longer, clearer clip.
70–100
Likely face swap or edit
Strong signs the faces were swapped or altered. Don't act on the video until you've checked the source.
No face found No clear face in the clip, so there's no deepfake score.
How to spot a deepfake video yourself
A video deepfake detector is quicker, but you can catch a lot yourself if you slow the clip down. Most fakes slip when the head turns, the light changes or the person speaks fast.
Watch it frame by frame
- The face flickers or slides when the head turns.
- Lips lag behind the audio or don't shape the words.
- Blinking is too rare, too regular, or missing.
- Light on the face doesn't change as the person moves.
- The face is sharper or blurrier than the rest of the frame.
- Hair, glasses or earrings warp at the edge of the face.
On a live video call
This tool checks recordings, not live calls. While you're on the call, try these:
- 1Ask them to turn their head fully to the side.
- 2Ask them to pass a hand slowly in front of their face.
- 3Ask something only the real person would know.
- 4Hang up and call back on a number you already have.
Signs of a low-end deepfake video
Shimmering face edges, a face that flickers between frames, a mouth out of sync with the voice, and stiff, repeating expressions.
Where deepfake videos do damage
Fake videos are built to make people act fast: pay, share or panic. Here's what each scam looks like and what to do.
The fake CEO call
Staff are told on a video call to move money urgently. Save the recording and confirm through a known channel before anyone pays.
Celebrity investment ads
A famous face promotes a trading app or crypto scheme. Check the clip, and never invest through an ad.
Election-week clips
A candidate appears to say something explosive days before a vote. Check it before you share it.
Job interview fraud
A remote candidate's face doesn't quite match their ID. Record the interview, with consent, and check it.
Sextortion threats
Someone threatens to share a fake explicit video of you. Don't pay. Save the evidence and report it.
Viral hoaxes
A clip shows something too wild to be real. Check it before it spreads any further.
What a video deepfake check can't tell you
A video deepfake detector gives you evidence, not proof. Results get less reliable when:
- the clip is a screen recording or has been re-uploaded many times
- the face is small, turned away, or on screen only for a moment
- the video is very short or very low resolution
- there's no face in the clip, so there's no deepfake score
It can't watch live calls. Save a recording, with consent where required, and upload that.
Video deepfake detector FAQ
It's a tool that checks a video for signs that a real person's face or lip movements were swapped or altered with AI. This one gives you one face score for the whole clip.
Watch the face edges, blinking, lip sync and lighting as the head moves, then run the clip through the video deepfake detector. Upload the original file if you can; screen recordings hide the signs.
No. It checks recorded files. Save the recording or a short clip, with the other person's consent where required, and upload it.
Download the original if the platform allows it, or screen-record the clip at the highest quality you can, then upload it. Re-encoded copies make the score less reliable.
The face check looks at faces, not audio. For a cloned voice, upload the audio to our AI Voice Detector.
The video check returns one score for the faces across the whole clip, not one per frame, so there's nothing to draw. Photos get a box and a score for each face.
Shimmering edges around the face, a face that flickers between frames, lips out of sync with the voice, and stiff, repeating expressions.
Signing up gives you free credits, but video uses them quickly: a check costs 4 credits per second, so a 10-second clip costs 40 credits. Credit packs and plans cover longer clips.
Uploads are processed only to run the check; see our Privacy Policy for exactly how videos are handled and retained.
