How it works

Quick Scan vs Deep Scan: which should you use?

Quick Scan is free and fast; Deep Scan checks every second of picture and speech. What each one does, how long it takes, and when the upgrade is worth it.

Video Verifier has two ways to check a video. Both give you a headline answer like "92% AI" or "88% Real", a plain-language verdict, and the evidence behind it. The difference is how much of the video they examine.

Quick Scan: a fast first look

Quick Scan samples the video: a spread of frames across the whole clip and a set of speech segments. It runs our core checks on them, including the in-house motion model, the AI-pixel scan, the voice check, Content Credentials and metadata.

  • Time: usually well under a minute.
  • Price: free, no sign-up, a few scans a day.
  • Best for: the everyday "is this real?" moment, like a clip in a family group or a video in your feed.

Deep Scan: the full sweep

Deep Scan examines a frame every second of the video plus the key moments, up to 12 times more frames than Quick Scan, and listens to the entire soundtrack in overlapping windows. For links, it fetches a sharper copy where available.

It also adds a score breakdown: how strongly the evidence points to fully AI-generated, to real footage with AI added (like a cloned voice over real video), or to real. And you get the full report with every finding and timestamp, plus a PDF.

  • Time: grows with the video's length. Around 45 seconds for a 30-second clip, about 2 minutes for a 2-minute video, and several minutes for the longest videos.
  • Price: a small one-time payment per video, or included in a monthly plan. See Pricing.
  • Best for: videos you're going to publish, report, act on or argue about.

Why more frames matter

A fake doesn't have to be fake everywhere. A real video can have a few seconds where a face is swapped, an AI-generated insert, or a cloned voice over only one sentence. Sampling can step right over those moments. Checking every second, and every second of speech, gives the detectors many more chances to catch a short manipulation, and makes the overall answer steadier.

Which one should you pick?

  • Use Quick Scan when you want a fast read and the stakes are low.
  • Use Deep Scan when the answer matters: before you post it, report it, forward it to a large group, use it as evidence, or make a decision based on it.
  • Upgrade after a Quick Scan if the result is close to 50/50 or the report mentions parts that look mixed. A Deep Scan has much more to go on.

Whichever you choose, the result is strong evidence, not a final word. No detector is 100% sure, which is why every report shows its reasons and says when a check was unavailable.

Tips for the best result

  • Paste the original link rather than a forwarded copy. See why re-uploads make fakes harder to catch.
  • Videos up to 10 minutes and 50 MB work, depending on your plan.
  • Private posts can't be fetched by link: download the video and upload the file.
