Actual analysis path
What the video detector actually reviews
The browser samples up to 10 frames across the full clip. Each frame keeps its timestamp so repeated anomalies can be compared across time.
Look for repeated conflicts
Face boundaries, objects, lighting and motion are reviewed at multiple timestamps.
Keep single-frame noise uncertain
One compression artifact is not enough for a high-risk result; repeated evidence matters more.

WhatsApp and social video
Check the full clip, then check its source
The detector samples the full duration, not only faces or the opening seconds. A platform copy can still hide evidence that exists in the original file.
1. Save the original
For WhatsApp or another messenger, download the attached video file. A screen recording adds another compression layer and should be a fallback.
2. Review the whole timeline
Up to 10 timestamped frames are spaced across the clip. The review includes faces, objects, text, lighting and repeated changes between samples.
3. Verify outside the file
Contact the sender through a known channel and look for an original publication. A detector result cannot authenticate the person, caption or event.
If the concern is specifically a replaced identity, use the face swap detector. For payment or impersonation scams, follow the source-backed fraud verification workflow.
Video Deepfake Detection — Is This Video Real or AI?
DeepFakeCheck helps you review face-swap, AI-generated and AI-edited video. Upload an MP4, MOV or WebM file up to 100 MB. The browser samples up to 10 timestamped frames across the full duration, then the analysis model reviews repeated visual inconsistencies. No signup is required; analyzed content is retained for up to 7 days, then deleted.
How deepfake video detection works
The current pipeline is deliberately simple and transparent:
- Uniform frame sampling. Up to 10 frames are spaced across the full clip, not just the opening seconds.
- Timestamped review. Each sampled frame keeps its original timestamp so a visible issue can be checked across multiple moments.
- Visual reasoning. The model reviews face boundaries, object continuity, lighting and physically implausible changes across the sampled frames.
- Conservative conclusion. A single compression block or blurred frame is not enough for a high-risk result. Repeated, independent conflicts carry more weight.
What the review may surface
The sampled evidence may surface patterns associated with several common manipulation types:
- Face swaps: repeated boundary, skin-tone or lighting conflicts around the face and hairline.
- Fully generated video: objects, anatomy, text, reflections or shadows that change implausibly between samples.
- AI editing: a localized region that changes differently from the surrounding scene.
Common use cases for the video detector
- Newsrooms verifying viral political clips before broadcasting.
- KYC and fraud teams spotting deepfake video during identity verification — a fast-growing attack vector in fintech.
- Influencer managers and brands monitoring whether the talent they represent is being deepfaked in scam videos.
- Family members checking suspicious video calls — voice-clone plus face-swap scams targeting older relatives are now common.
Video detection FAQ
How much of the clip is reviewed? The current browser pipeline selects up to 10 frames across the entire duration. Because it does not inspect every frame, a very short manipulation between samples can be missed.
Does it work on heavily compressed social video? It can still review visible inconsistencies, but compression and resizing remove forensic detail and may also create false artifacts. Treat these results with lower confidence.
Can it prove a video is authentic? No. A low-risk result only means the sampled frames did not contain strong evidence. It does not certify every frame or the original source.
What does "high risk" mean? It means the sampled evidence contains multiple patterns associated with AI generation or manipulation. It does not establish malicious intent.
Is my video private? The analyzed content is transmitted over HTTPS, retained securely for up to 7 days to improve detection quality, and then automatically deleted.
