How to Know If a Video Is AI Generated or Real

Part 1. What Does "AI-Generated Video" Mean?

In simple terms, an AI-generated video is a piece of visual media created using artificial intelligence algorithms rather than traditional filming. Unlike traditional videos that capture light through a camera lens, AI videos are "synthesized" from vast datasets of existing imagery.

Common Types of AI Video:

• Text-to-Video: Creating a full scene simply by typing a description (e.g., "A golden retriever surfing in Hawaii").
• Image-to-Video: Taking a static photo and using AI to animate it with realistic motion.
• AI Avatars / Talking Heads: Digital humans that "speak" a script with synchronized lip movements, often used for training or marketing.
• Deepfakes: Replacing a person's face or voice in an existing video with someone else's likeness.

Part 2. Why It's Getting Harder to Tell AI Videos Apart

In 2026, models like Kling 2.5 Turbo and VEO 3 have significantly reduced the "uncanny valley" effect. Here is why your brain might be tricked:

• Natural Physics: Modern AI now understands gravity and fluid dynamics better, making hair and clothing move realistically.
• Cinematic Filters: AI often applies high-end color grading and "film grain" that hides pixel-level artifacts.
• Social Media Compression: When a video is uploaded to platforms like Instagram or X, the quality drop-off often masks the subtle glitches that would reveal it as AI.

Part 3. How to Tell If a Video Is AI Generated

To catch a deepfake, you need to look past the "vibe" and focus on the technical inconsistencies.

Visual Clues That a Video May Be AI Generated

When watching a person in a suspicious video, the first place to look is their eyes and mouth. Human eyes have a natural "wetness" and reflect light in specific, sharp patterns, whereas AI eyes often look slightly "flat" or glassy. You should pay close attention to the blinking-real humans blink at irregular intervals, but AI often generates rhythmic, robotic blinking or skips it entirely. Additionally, look at the teeth when the person speaks; AI frequently struggles to define individual teeth, often rendering them as a blurry white "unitooth" or causing them to shift and change shape mid-sentence.

Key Red Flags: Pay attention to irregular blinking patterns, blurry dental structures, and a lack of natural light reflection in the pupils.

Motion and Physics Errors to Watch For

While AI has improved at simulating gravity, it still creates "dream-like" physics errors. Real objects have weight and momentum; when a person walks, their head bobs and their weight shifts visibly. In AI videos, characters often seem to "glide" or "float" across the ground without a true sense of gravity. Another common error occurs with clothing and hair; in a real video, wind affects these elements realistically, but in AI videos, they may move in a fluid, "liquid" way that defies the laws of physics or clip through the character's body.

Key Red Flags: Watch for a lack of "weight" in movements and clothing or hair that flows like liquid rather than reacting to wind and gravity.

Audio and Lip-Sync Red Flags

The audio track often reveals what the eyes miss. In 2026, AI voices can sound incredibly human, but they often lack the "micro-emotions" of real speech, such as subtle intakes of breath or changes in pitch based on the meaning of a sentence. Most importantly, check the synchronization between the mouth and the sound. During fast speech or complex words (specifically those involving the letters B, M, and P), the AI's lip movements may lag or fail to close the mouth entirely. If the audio is "too clean"-meaning there is absolutely no background noise or room atmosphere-it is likely a synthesized voice-over.

Key Red Flags: Listen for "perfect" audio lacking ambient noise and watch for lip movements that don't quite match hard consonant sounds.

Contextual and Logical Signs

Finally, step back and look at the logic of the scene. AI often generates backgrounds that make no sense upon closer inspection-street signs with gibberish text, clocks with thirteen hours, or stairs that lead to nowhere. Ask yourself if the event being shown is actually plausible. If a video shows a high-profile politician in a casual setting saying something completely out of character, and the video has no original source or metadata, the context suggests it is a deepfake. AI-generated content often looks "too perfect" or cinematic for a supposedly "leaked" or casual mobile phone video.

Key Red Flags: Look for gibberish text in the background, impossible architecture, and a lack of verifiable metadata or a reputable source.
