In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game , a DVD , or the signal from a TV card .
The second generation PureVideo HD is sometimes called "PureVideo HD 2" or VP2, although this is not an official Nvidia designation. It corresponds to Nvidia Feature Set A (or "VDPAU Feature Set A"). This is the earliest generation that Adobe Flash Player supports for hardware acceleration of H.264 video on Windows.
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU -intensive operations such as iDCT , motion compensation and deinterlacing to be offloaded to the GPU .

VirtualDub supports both DirectShow and Video for Windows for video capture. Capture features include capture to any AVI variant, audio VU meters, overlay and preview modes, histogram, selectable crop area, video noise reduction, auto stop settings (based on capture time, file size, free space, and/or dropped frames), and designate alternate drive(s) for capture overflow.
Running windows are arranged into a stack – similar to a flip-style selector in a 1950s jukebox, or a Rolodex. In some systems, the user can press Alt-Shift-Tab to navigate backwards. Visual transitions are applied to each item while navigating. Common implementations of flip switching include Flip 3D in Windows and Shift Switcher in Compiz.

Video overlay is any technique used to display a video window on a computer display while bypassing the chain of CPU to graphics card to computer monitor. This is done in order to speed up the video display, and it is commonly used, for example, by TV tuner cards and early 3D graphics accelerator cards.
