Why AI Video Used to Be So Hard

Why AI Video Used to Be So Hard

Generating a single believable image is one problem. Generating dozens that all agree with each other and move naturally is a much harder one, and it only became practical recently.

Consistency across time

A video model has to keep a subject stable frame to frame. Early attempts produced flickering, warping, and subjects that drifted into something else.

Motion that looks physical

Natural movement has weight and timing. Getting a generated animal to move like a real body, not a paper cutout, took better models and more training.

Doing it fast enough

Even once quality was there, generating a clip in seconds rather than hours needed hardware and model efficiency that arrived only in the last couple of years.
