carykh demonstrates a script that speeds up the silent parts of a video while leaving speech at normal speed, to condense lectures and similar footage. It later became the Jumpcutter tool.

The full recording of Douglas Engelbart's 1968 demonstration, which introduced the mouse, hypertext, video conferencing, word processing, and real-time collaborative editing. It runs about 100 minutes.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

A four-minute Emacs Rocks screencast demonstrating the multiple-cursors package for Emacs. It shows how editing at many places at once can replace repetitive manual edits.

Highlights from Doug Engelbart's December 1968 demonstration at SRI, the first public showing of the mouse, hypertext, windows, real-time collaborative editing and shared-screen teleconferencing. This is a roughly six-minute condensed version of the full demo.

Adobe's VoCo demo from the MAX 2016 Sneak Peeks, co-hosted by Jordan Peele, showing software that changes words in a voiceover by typing new ones.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.

A SIGGRAPH Asia 2013 research demo of 3-Sweep, a tool for extracting editable 3D objects from a single photo using a few user strokes. It predates modern AI image tools.

A promotional video for Leap, the navigation technology invented by Jef Raskin, demonstrated on the Canon Cat computer around 1987. It shows keyboard-driven search and cursor positioning in place of a mouse.

A short Italian-language clip about the Canon Cat, a text-oriented personal computer from Canon designed by Jef Raskin, who started the Macintosh project. It shows the machine in use.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

Adobe's sneak-peek demo of Content-Aware Fill ahead of Photoshop CS5, showing objects being removed and areas repaired seamlessly with the delete key.

Part 2 of an old Microsoft Research demo of Intentional Programming, showing the compiler side of a system that stores programs as abstract structure rather than text. The uploader says the companion editor clip is clearer.

SethBling shows MarI/O, a program using neural networks and the NEAT genetic algorithm to learn to play Super Mario World. The description links the source code, the paper and background reading.

The Google I/O 2009 keynote introducing Google Wave, a real-time collaborative communication and document platform. It includes a long live demo and the developer preview announcement.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

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

A brief demo of the Smalltalk debugger, including defining a method that doesn't exist yet while the program is stopped mid-crash.
