A screencast is a digital recording of computer screen output, also known as a video screen capture or a screen recording, often containing audio narration. The term screencast compares with the related term screenshot; whereas screenshot generates a single picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, that can be enhanced with audio narration and captions.
Fraps is a benchmarking, screen capture and screen recording utility for Windows developed by Beepa. It can capture from software that uses DirectX and OpenGL, such as PC games.
AMD Radeon Software is a device driver and utility software package for AMD's Radeon graphics cards and APUs. Its graphical user interface is built with Electron and is compatible with 64-bit Windows and Linux distributions.
This page provides a comparison of notable screencasting software, used to record activities on the computer screen. This software is commonly used for desktop recording, gameplay recording and video editing. Screencasting software is typically limited to streaming and recording desktop activity alone, in contrast with a software vision mixer, which has the capacity to mix and switch the output between various input streams.
Snagit is screen capture and screen recording software for Windows and macOS. It is created and developed by TechSmith and was first launched in 1990. Snagit is available in English, French, German, Japanese, Portuguese and Spanish versions.

High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding. In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware.
The HTML5 specification introduced the video element for the purpose of playing videos, partially replacing the object element. HTML5 video is intended by its creators to become the new standard way to show video on the web, instead of the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers. As of 2020, HTML5 video is the only widely supported video playback technology in modern browsers, with the Flash plugin being phased out.
VP9 is an open and royalty-free video coding format developed by Google.
NvidiaShadowPlay is a hardware-accelerated screen recording utility available as part of Nvidia's GeForce Experience software for GeForce GPUs. Launched in 2013, it can be configured to record a continuous buffer, allowing the user to save the video retroactively. ShadowPlay is supported for any Nvidia GTX 600 series card or higher.

AOMedia Video 1 (AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet. It was developed as a successor to VP9 by the Alliance for Open Media (AOMedia), a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors. The AV1 bitstream specification includes a reference video codec. In 2018, Facebook conducted testing that approximated real-world conditions, and the AV1 reference encoder achieved 34%, 46.2% and 50.3% higher data compression than libvpx-vp9, x264 High profile, and x264 Main profile respectively.
Nvidia NVDEC is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU.
macOS Mojave is the fifteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. Mojave was announced at Apple's Worldwide Developers Conference on June 4, 2018, and was released to the public on September 24, 2018.
