How to Spot AI Videos From Frames That Stay on Your Device

Spotting an AI video starts with a file you can actually open, and with a number you know how to read. Detect AI Video does not watch the clip as a movie. Your browser lifts stills out of it, those stills are scored, and you get an average plus a look at the frame that scored highest. The number is a probability label. It is not proof.

What the average is allowed to mean

The product prints three labels. An average at or above 0.7 is marked likely made by a generator. An average at or below 0.3 is marked likely not. The band in between is marked unsure. Those cutoffs are the words this tool uses. They are not a measured accuracy study, and the site does not present them as one.

The hottest single frame can point you at a moment that sits above the rest of the clip. Use that moment as a place to look again, next to where the file came from.

What leaves the computer

The video file stays on the device. Every two seconds the browser grabs one JPEG, and it stops at thirty frames, which is a clip of at most sixty seconds. Those JPEGs are what Sightengine's genai model scores. The full movie is not uploaded.

The tool remembers which stills it already scored. Sending that same set through again does not charge a second time.

Compression, a second encode, and mixed edits

A heavy squeeze, another encode, or an edit laid over either kind of footage can push the score the wrong way. Camera footage can be marked, and generated footage can slip under the line. No checker is right on every file. Read the label beside the source, not instead of it.

Do not lean on the result by itself to accuse someone, and do not treat it as enough for a legal, hiring, academic, or news decision.

Credits and the packs on the price list

One credit pays for each started group of eight frames, about sixteen seconds of video. Thirty frames, a full minute, come to four credits. A check that fails puts the credits back.

The published packs are 3 credits for $0.99, limited to one purchase per account on each UTC day; 60 credits for $9.90; 200 credits for $24.90; and 600 credits for $59.90. A pack lasts 365 days. A free check is not part of the product. If card checkout is not open, the pricing page says that payments are still on the way.

Which files you can hand it

Pick a file the browser can play. A link from TikTok, YouTube, or another site is not accepted. The cap is sixty seconds.

Check a clip you already have

Open the detector, sign in, and choose the file. Watch the average and the frame that scored highest, then decide what that label is worth next to the source of the clip. Pack prices are listed beside the tool when you need more credits.
