If you’ve landed here with a suspicious video and the question “is this video AI generated?” — you are in the right place. This guide gives you a fast, practical answer using free tools available right now.
The Fastest Method: Use Our Free Detector
Upload your video to our free Sora AI Detector. You will receive an AI probability score and a breakdown of the three key metrics — colour variance, edge complexity, and texture uniformity — within seconds. No signup, no cost. Supports MP4, AVI, MOV, and other standard formats.
What the Score Means
- High probability (70%+): Strong indicators of AI generation present. Treat with significant suspicion and verify further.
- Medium probability (40–70%): Mixed signals. Could be AI, could be authentic footage with unusual characteristics. Apply manual inspection.
- Low probability (under 40%): Likely authentic, but no tool is 100% certain. Corroborate with other evidence for high-stakes decisions.
Quick Visual Checks
While the detector runs, do a quick visual scan for the most common signs of AI-generated video: wrong finger count, impossibly smooth skin, background flickering, physics errors, or text that looks like text but is actually gibberish up close.
If You Still Are Not Sure

Understanding Your Result: A Deeper Explanation
When you get a result back from the detector, you are seeing three underlying signals combined into one score. Understanding what each signal means helps you decide how much weight to give the result.
Colour Variance Score
This measures how “organic” the colour behaviour across frames is. Real video has colour variation driven by physical light. AI video has colour variation driven by learned statistical distributions. When colour variance is flagged, it means the colour transitions across frames follow an AI-generation pattern rather than a camera-capture pattern. This is particularly reliable for Sora 2, whose diffusion-transformer architecture has a characteristic colour signature.
Edge Complexity Score
Cameras create complex optical effects at object boundaries. AI models simulate these effects but produce measurably different edge profiles. High edge complexity flagging means the boundaries between objects look too clean, too uniform, or too smooth to be consistent with optical lens physics.
Texture Uniformity Score
Real surfaces are organically imperfect. AI surfaces are statistically too consistent. High texture uniformity flagging means surfaces in the video are too uniform to match real-world material properties.
When the Score Is Borderline (30–60%)
A borderline result does not mean the tool has failed — it means the video has mixed signals. This can happen with: heavily filtered or post-processed real video, CGI or animation that is not an AI deepfake, very short clips with insufficient frame data, or AI video with aggressive post-processing designed to obscure artifacts. In these cases, apply the manual visual inspection checklist from our 10 signs of AI-generated video and check metadata with ExifTool.
Common Scenarios Where You Might Check a Video
- A viral social media clip shows a celebrity doing something surprising: High-profile people are common deepfake targets. Run it before sharing.
- Breaking news footage appears with no other camera angles: Real events produce multiple independent recordings. Unique dramatic footage with no corroboration is suspicious.
- You receive a video in a message claiming to show someone you know: Voice cloning and face-swap AI can impersonate known individuals convincingly.
- A video job interview candidate looks slightly “off”: Real-time deepfake imposters are an emerging HR risk.
After You Have Your Result
A high-probability result means: do not share, do not rely on this video for any important decision, apply further verification using our complete detection guide, and if it is newsworthy misinformation, report it to the platform. A low-probability result means: this video does not show obvious AI generation signals, but for high-stakes decisions, still corroborate with evidence.
