Animator Noodle explains why frame interpolation does not make animation better, covering timing, easing, smear frames and using the wrong tool for the job. A pinned correction says the video is partly outdated given later AI developments.

The original 2012 screencast introducing Meteor, a JavaScript framework for building web apps quickly. It demonstrates realtime updates, latency compensation and low boilerplate.

Ramesh Raskar presents femto-photography, a technique that captures a trillion frames per second, fast enough to show light itself moving through a scene. He discusses possible uses such as cameras that see around corners or inside the body.

A how-to video on datamoshing, the glitch-art technique of removing keyframes so that motion data smears across video. It walks through the tools needed, such as ffmpegx and Avidemux, though the author notes parts are outdated.

A short clip of Richard Feynman answering an interviewer's question about why magnets repel, explaining that a 'why' question depends on a shared framework of understanding. It illustrates how hard it is to explain fundamentals to a layperson.

Robert Miles explains reward modelling, in which an AI learns what humans want from their preference comparisons instead of a hand-written reward function. He walks through the 2017 paper on deep reinforcement learning from human preferences.

Tom Scott explains why confetti and snow wreck video quality, using interframe compression and bitrate. He demonstrates it live by changing the quality on screen.

Veritasium explains the Dzhanibekov effect, also called the tennis racket theorem, where a spinning object flips unexpectedly about its intermediate axis. The video gives an intuitive account of the underlying rotational dynamics, drawing on Terry Tao's explanation and the original papers.

Malcolm Gladwell's TED talk on how Howard Moskowitz found that there is no single perfect spaghetti sauce. He draws a larger point about choice, preference and happiness.

Every Frame a Painting analyzes how Jackie Chan stages action comedy, with nine principles such as starting from a disadvantage, using the environment, clear shots, and keeping action and reaction in the same frame.

An Every Frame a Painting video essay asking why Marvel films lack memorable musical themes. It blames temp tracks and directors scoring to filler music.

An Every Frame a Painting video essay on how Akira Kurosawa used movement, weather and composition to tell stories. It draws on clips and interviews with other filmmakers.

A video essay from Every Frame a Painting about Vancouver, a major film production city that almost never appears onscreen as itself. It shows clips of films and TV shot there that pass the city off as somewhere else.

An Every Frame a Painting video essay on Michael Bay's style, 'Bayhem', covering his camera movement, composition, color and editing. It argues that even if you dislike his films, they teach something about visual perception.

An Every Frame a Painting video essay analysing how Edgar Wright creates visual comedy through framing, camera movement, editing, sound effects and music.
