Early 16-bit ISA capture cards emerged in the early 90s. These cards were supported by VIDCAP as part of the Video for Windows package. One early card was a sandwich of two cards as early processors needed more logic to even get up to 15 frames per second. PCI capture cards offered 30 frames per second.
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 .
Most "Windows accelerator" video cards were 2D-capable fixed-function processors that received 2D drawing commands and pixel data sent from the CPU, resulting in faster window drawing. [3] The reduced burden on the CPU, combined with the smaller data stream needed for the required instructions, resulted in improved performance compared to "dumb ...
A DataPath VisionRGB-E2s expansion card with two frame grabbers. A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream.
Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed. [5] The eighth annual MPEG-4 AVC/H.264 video codecs comparison showed that Quick Sync was comparable to x264 superfast preset in terms of speed, compression ratio and quality (); [6] tests were performed on an Intel Core i7-3770 processor.
On Windows Vista and Windows 7, the desktop can be captured if Windows Aero is enabled. Windows 8 game capture works, but not desktop capture as of version 3.5.99. [3] Fraps records video at high resolution if the computer is sufficiently powerful. The maximum supported resolution is 7680×4800. [4] Fraps uses a proprietary codec.
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
Comparison of a slow down video without interframe interpolation (left) and with motion interpolation (right) Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate film, video or animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display ...
