Demo recording
Under demo recording means the recording of movements to a computer program . This also includes computer games . A subroutine of the computer program, a plug-in or a module of an emulator record all inputs made by the user. The recordings can be saved in a list and viewed.
This list could now e.g. B. stand that at a precisely defined point in time key "A" was pressed, and was released again at a later, precisely defined point in time.
The saved list can then, if the appropriate means are available, be reloaded into the program in order to start a demo playback.
By the term accurate recording of user input, it is for. B. possible to look at the hike through a computer game a second time. Since the resulting demo recording files are usually quite small (e.g. only a few kilobytes for NES games ), recorded records can be quickly distributed over the Internet.
Demo recording is of particular interest in the speed run scene, which is about playing a computer game as quickly as possible. Demo recordings ensure that those interested can experience the game a second time “live” in “real time”. Only through speed runs is manipulation, e.g. B. in the interest of even faster play through, excluded. A video file that would have recorded the speed run could have been shortened by editing programs and thus manipulated. Thus, demo recordings are the only "legitimate" source of evidence for a successful speed run.
Apart from computer games, demo recording can be used to e.g. B. to automatically simulate the movement of the mouse pointer . This routine use programs Shareware - Pop-up click away messages.
