What this checker can and can’t catch
We want to be straight with you. IsThisVideoReal is strongest at spotting fully AI-generated videos and any video that still carries its Content Credentials or camera data. Face-swap deepfakes made from real footage keep much of the original camera’s look, which makes them harder for a general-purpose model. Use the result together with the checks below.
How to spot a face-swap deepfake
- Edges of the face. Shimmer along the jaw, hairline or ears, especially when the head turns.
- Side profiles. Face swaps are trained mostly on front-facing images and often break at 90°.
- Occlusion. Hands, glasses or a microphone passing in front of the face cause flicker or blending.
- Blinking and gaze. Unnatural blink rhythm or eyes that don’t track what the person is looking at.
- Lip sync. “P”, “B” and “M” sounds need closed lips — dubbed deepfakes often miss them.
- Skin tone mismatch. Face colour or lighting that doesn’t match the neck and hands.
FAQ
What’s the difference between a deepfake and an AI-generated video?
A deepfake usually alters real footage — swapping a face or re-syncing lips to new audio. A fully AI-generated video is created from scratch by a model like Sora or Veo. Our visual model is strongest on fully generated clips; face swaps on real footage are harder for any general detector.
Can this detect a face swap on a video call?
Not live. You can record the call and check the file, but real-time face-swap detection needs specialised tools. Ask the person to turn their head fully sideways or pass a hand in front of their face — face swaps often glitch.
What should I do if I think a video of me is a deepfake?
Save the file and the link, note where and when it was posted, and report it to the platform. Many platforms have specific reporting routes for synthetic or impersonating media.
