Why Do AI Videos Look Like Dreams? – free checklist (episode 21)

Why it matters

An AI video tool draws what looks right, using patterns it learned from other videos. It isn't filming a real scene, and details can change while the video plays.

The 5 checks

0 of 5 done

Follow one thingPick one animal, person or object. Watch it from start to end. Does it stay the same?Try: Is the dog at the start still the dog at the end?General good practice.
Count it twiceCount legs, people or cars near the start. Count again near the end. Did anything appear or vanish?Try: Four legs at the start. Still four at the end?General good practice.
Pause and comparePause near the start and again near the end. Put the two pictures side by side.Try: Same shapes? Same colors? Same number of things?General good practice.
Check the physicsDo things fall, pour and bounce the way they do in real life?Try: Watch a splash, a bounce or a dropped cup.Researchers found weak physics in several video AI models (a 2025 study).
Check the sourceA clean-looking video can still be AI. See who posted it first.Try: Search for the original post or a news report.General good practice.

Rule of thumb

odd details are a clue, not proof.

The dog-and-cat story and the five checks are our own illustration and general good practice; the flipbook is an analogy, not how the tool works inside.
