Detecting Sora video

Can Witness detect Sora video videos?

Witness scans video for signs of AI generation and shows a per-frame view. Video detection is harder than image detection and results vary a lot with compression and clip length, so treat it as a signal only.

Video detection is in beta

Some AI video tools add Content Credentials or visible watermarks. Both can be cropped or stripped.

What helps and what hurts

What helps

  • Scan the original file, not a screen recording.
  • Check the per-frame timeline for where the signal appears.
  • Look for a watermark and check the source.

Where detection gets harder

  • Social platforms recompress video heavily.
  • Short clips give less to work with.
  • New video models appear faster than detectors update.

How to read this page

  • Coverage statements come from Witness's own internal evaluation, not an independent benchmark.

Frequently asked questions

Can Witness detect Sora videos?

It can sometimes flag AI-generated video, but no accuracy is claimed for Sora in particular. Treat results as a hint.

Can it scan a video on a web page?

Is a Witness result proof?

No. Witness gives a likelihood and a confidence percentage, plus an explanation. Use it as a second pair of eyes, not as a final ruling.
