Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images are captured or displayed. This definition applies to film and video cameras , computer animation , and motion capture systems.
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. These cards could also handle capturing VHS tapes etc. but VHS image quality was poor so many adopted new video cameras until eventually digital cameras surfaced.
Doing so also unlocks NVIDIA Frame Buffer Capture (NVFBC), a fast desktop capture API that uses the capabilities of the GPU and its driver to accelerate capture. [7] Professional cards support between three and unrestricted simultaneous streams per card, depending on card model and compression quality, [2] the restrictions were loosened in 2023 ...
Nvidia ShadowPlay is a hardware-accelerated screen recording utility available as part of Nvidia's GeForce Experience and Nvidia App softwares for GeForce GPUs. Launched in 2013, it can be configured to record a continuous buffer, allowing the user to save the video retroactively.
This animation demonstrates the interline twitter effect using the Indian Head test card. On the left are two progressive scan images. Center are two interlaced images. Right are two images with line doublers. Top are original resolution, bottom are with anti-aliasing. The two interlaced images use half the bandwidth of the progressive one.
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.
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.
Few capture in standard TV-video formats (480p60, 720p60, 1080i30), recording in either non-TV resolutions (320x240, 640x480) or slower frame rates (15 or 30 fps). A multipurpose device used as a camcorder offers inferior handling, audio and video performance, which limits its utility for extended or adverse shooting situations.
