AI Video: The biggest clue a video might be made with AI

AI Video: Artificial intelligence is rapidly transforming the internet, making it harder than ever to tell whether videos online are real or generated by AI.

According to tech experts, one of the most common warning signs of AI-generated videos today is surprisingly simple: very low video quality.

Grainy, blurry or heavily pixelated footage may indicate that a clip was created using AI technology.

Why blurry videos can hide AI mistakes

Experts say AI-generated videos often contain small visual errors. However, these mistakes are easier to detect when the video quality is high.

Hany Farid, a computer science professor at University of California, Berkeley, explains that the clearer the video, the easier it becomes to notice subtle inconsistencies.

These errors might include:

• Unrealistically smooth skin textures
• Odd patterns in clothing or hair
• Background objects moving in unnatural ways

When videos are intentionally blurred or compressed, these clues become harder for viewers to detect.

In some cases, people who create fake videos deliberately lower the resolution so that the AI’s imperfections are hidden.

Many viral videos are AI-generated

Several viral videos circulating on social media platforms like TikTok and Instagram have later been revealed to be AI-generated.

Examples include:

• A viral clip of rabbits jumping on a trampoline
• A romantic scene on the New York subway
• A video of a priest delivering a surprising political sermon

All of these videos attracted millions of views before viewers discovered they were artificially created.

Short videos are another clue

Another indicator experts often look for is video length.

According to Hany Farid, many AI-generated videos are extremely short — often between 6 and 10 seconds.

This is because generating longer AI videos is more difficult and expensive, and the longer a clip runs, the more likely the AI system is to produce visible errors.

Creators sometimes stitch multiple short clips together, which may result in noticeable cuts every few seconds.

AI technology is improving rapidly

Despite these warning signs, experts warn that these clues may disappear soon.

Matthew Stamm, who leads the Multimedia and Information Security Lab at Drexel University, says AI video tools are improving very quickly.

He predicts that many of today’s visual clues could disappear within a few years as the technology becomes more advanced.

Why we can no longer rely on our eyes

Because AI tools are becoming more sophisticated, experts say people should not rely solely on visual clues to determine whether a video is real.

Instead, viewers should pay attention to the source and context of the content.

Digital literacy expert Mike Caulfield says verifying where a video came from and who posted it is becoming more important than analysing the image itself.

Just as people question written information online, experts say audiences must now develop the same skepticism toward images and videos.

The future of verifying digital content

Researchers and technology companies are currently working on systems that could help verify digital media.

Some proposals involve embedding authentication data directly into images and videos at the moment they are created. AI-generated media could also be automatically labelled to show that it was produced by artificial intelligence.

However, experts believe solving the problem will require a combination of technology, education, stronger policies and improved public awareness.

As AI-generated content continues to grow across the internet, learning how to critically evaluate online videos may become an essential digital skill.
