How we check if a video is real
Most “AI video detectors” send your file to a paid API and give you a single number. We run three independent checks on your own device and show you every piece of evidence, so you can judge for yourself.
Reads Content Credentials
Sora, Veo, Adobe Firefly and others can stamp videos with C2PA “Content Credentials”. If the file says it was AI-generated, we tell you.
Inspects the file
Phones write camera make, model and location into the file. Generators don’t. We also read the encoder, frame rate, length and audio track.
Scans the frames
An open-source AI-image classifier checks 10 moments of the video — full frame and a close-up crop — for synthetic texture and lighting.
Is this video AI? Why it’s getting harder to tell
Text-to-video models like OpenAI’s Sora 2, Google’s Veo 3, Kling, Runway and Hailuo now produce clips with realistic motion, lighting and even synchronized sound. Fake news clips, “caught on camera” moments, celebrity endorsements and street interviews spread across TikTok, Instagram Reels, YouTube Shorts and WhatsApp before anyone checks them.
The companies behind these tools do add labels. Sora videos carry a moving watermark and C2PA metadata; Google embeds an invisible SynthID watermark and Content Credentials in Veo output. But watermarks get cropped or blurred, and metadata disappears the moment a clip is re-uploaded or screen-recorded. That’s why a good check combines the file evidence with a look at the pixels — and why you should still use your own eyes.
8 signs a video is AI-generated
- Hands, teeth and textCount fingers, watch hands grip objects, look at teeth when people talk, and read any signs or labels. Text that melts or changes between frames is a giveaway.
- Physics that doesn’t add upLiquids that pour wrong, objects passing through each other, hair or fabric that ignores wind, footsteps that don’t match the ground.
- Things that morphPause and scrub slowly. Background people, cars and jewellery often change shape, merge or vanish when the camera moves.
- Too-perfect lighting and skinGlossy, poreless skin and cinematic light in a supposedly casual phone video are common with Veo, Sora and Kling.
- Clip length and cutsMost generators make 4–10 second shots. A viral “single take” that hard-cuts every 8 seconds is suspicious.
- Watermarks and cropsLook for a Sora cloud logo, a small “Veo” mark bottom-right, or an oddly tight crop where a watermark may have been cut out.
- Audio that’s slightly offLip sync drifting, voices without room echo, or ambient sound that loops are common in generated clips with audio.
- No original sourceSearch for the earliest upload. Real events usually have multiple angles and witnesses; AI clips often trace back to one account.
Reading your result
The file says so
Content Credentials or metadata name an AI generator. This is the strongest evidence you can get.
Mixed signals
Usually a re-uploaded clip with no metadata where the frames could go either way. Use the visual checklist and look for the original source.
Camera evidence
Phone or camera tags are present and the frames look like real footage. Remember: a real video can still be misleading or out of context.
Frequently asked questions
Is this video real or AI? How do I check?
Drop the video file into the detector above. It reads the file’s Content Credentials and camera metadata, then runs an open-source AI model over sampled frames and gives you a verdict with the evidence behind it. Combine that with the visual checks in our guide.
Is IsThisVideoReal really free?
Yes. There are no limits, no account and no paid tier. The analysis runs on your own device, so checking a video costs us nothing and we never need to cap you.
Do you upload or store my video?
No. Your video is never uploaded. Everything happens inside your browser tab. The only download is the AI model itself (once, then it’s cached).
How accurate is it?
When a video carries Content Credentials or camera data, the result is very reliable. When that data has been stripped (most social media downloads), the verdict depends on the visual model, which is far from perfect on the newest generators. Treat the score as evidence, not proof.
Can it detect Sora, Veo, Kling and Runway videos?
It detects their Content Credentials and metadata when present, and the visual model looks for synthetic image patterns common to all of them. Re-uploaded clips without metadata are harder; see our Sora and Veo pages for generator-specific tells.
Can I check a TikTok, Instagram or YouTube link?
Not directly — to keep everything private and free, the tool works on video files. Save or screen-record the clip, then drop the file here. Note that platforms strip metadata, so the original file (if you can get it) gives a better answer.
Why does the first check take longer?
The first time, your browser downloads the open-source AI model (about 163 MB, or 57 MB in Lite mode). After that it’s cached, and checks take a few seconds.
Does it work on iPhone and Android?
Yes, in Safari and Chrome. Lite mode is recommended on older phones. Some HEVC videos may not decode in Chrome on Windows; Safari handles them, or convert to MP4.
