Video for Windows

From BetaArchive Wiki

Video for Windows (VfW) is Microsoft's multimedia framework which enables certain versions of its Windows operating system to play and encode digital videos.

The technology was developed as a response to Apple's QuickTime for Windows, which offered similar features. Apple later sued Microsoft because it supposedly used QuickTime code to improve Video for Windows. The framework was later replaced by ActiveMovie (later DirectShow) and also included Media Player.

Versions for Windows 3.1x could be obtained for free from Microsoft and installed as an add-on. Later versions for Windows 95 and NT were already included with the operating system.
