NVENC
Nvidia NVENC (short for Nvidia Encoder) is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler-based GeForce 600 series in March 2012. The encoder is supported in many livestreaming and recording programs, such as vMix, Wirecast, Open Broadcaster Software (OBS) and Bandicam, as well as video editing apps, such as Adobe Premiere Pro or DaVinci Resolve. It also works with Share game capture, which is included in Nvidia's GeForce Experience software. Consumer targeted GeForce graphics cards officially support no more than 3 simultaneously encoding video streams, regardless of the count of the cards installed, but this restriction can be circumvented on Linux and Windows systems by applying an unofficial patch to the drivers. Doing so also unlocks ''NVIDIA Frame Buffer Capture (NVFBC)'', a fast desktop capture API that uses the capabilities of the GP ...

GeForce 600 Series
The GeForce 600 series is a series of graphics processing units developed by Nvidia, first released in 2012. They served as the introduction of the Kepler architecture. Overview Where the goal of the previous architecture, Fermi, was to increase raw performance (particularly for compute and tessellation), Nvidia's goal with the Kepler architecture was to increase performance per watt, while still striving for overall performance increases. The primary way Nvidia achieved this goal was through the use of a unified clock. By abandoning the shader clock found in their previous GPU designs, efficiency is increased, even though it requires more cores to achieve similar levels of performance. This is not only because the cores are more power efficient (two Kepler cores using about 90% of the power of one Fermi core, according to Nvidia's numbers), but also because the reduction in clock speed delivers a 50% reduction in power consumption in that area. Kepler also introduced a new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kepler (microarchitecture)
Kepler is the codename for a GPU microarchitecture developed by Nvidia, first introduced at retail in April 2012, as the successor to the Fermi microarchitecture. Kepler was Nvidia's first microarchitecture to focus on energy efficiency. Most GeForce 600 series, most GeForce 700 series, and some GeForce 800M series GPUs were based on Kepler, all manufactured in 28 nm. Kepler also found use in the GK20A, the GPU component of the Tegra K1 SoC, as well as in the Quadro Kxxx series, the Quadro NVS 510, and Nvidia Tesla computing modules. Kepler was followed by the Maxwell microarchitecture and used alongside Maxwell in the GeForce 700 series and GeForce 800M series. The architecture is named after Johannes Kepler, a German mathematician and key figure in the 17th century scientific revolution. Overview Where the goal of Nvidia's previous architecture was design focused on increasing performance on compute and tessellation, with Kepler architecture Nvidia targeted their focu ...

Maxwell (microarchitecture)
Maxwell is the codename for a GPU microarchitecture developed by Nvidia as the successor to the Kepler microarchitecture. The Maxwell architecture was introduced in later models of the GeForce 700 series and is also used in the GeForce 800M series, GeForce 900 series, and Quadro Mxxx series, as well as some Jetson products, all manufactured with TSMC's 28 nm process. The first Maxwell-based products were the GeForce GTX 745 (OEM), GeForce GTX 750, and the GeForce GTX 750 Ti. Both were released on February 18, 2014, both with the chip code number GM107. Earlier GeForce 700 series GPUs had used Kepler chips with the code numbers GK1xx. First-generation Maxwell GPUs (code numbers GM10x) are also used in the GeForce 800M series and the Quadro Kxxx series. A second generation of Maxwell-based products was introduced on September 18, 2014 with the GeForce GTX 970 and GeForce GTX 980, followed by the GeForce GTX 960 on January 22, 2015, the GeForce GTX Titan X on March 17, 2015, and th ...

Nvidia NVDEC
Nvidia NVDEC (formerly known as NVCUVID) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. It is accompanied by NVENC for video ''encoding'' in Nvidia's Video Codec SDK. Technology NVDEC can offload video decoding to full fixed-function decoding hardware (Nvidia PureVideo), or (partially) decode via CUDA software running on the GPU, if fixed-function hardware is not available. Depending on the GPU architecture, the following codecs are supported: * MPEG-2 * VC-1 * H.264 (AVC) * H.265 (HEVC) * VP8 * VP9 * AV1 Versions NVCUVID was originally distributed as part of the Nvidia CUDA Toolkit. Later, it was renamed to NVDEC and moved to the Nvidia Video Codec SDK. Operating system support NVDEC is available for Windows and Linux operating systems. As NVDEC is a proprietary API (as opposed to the open-source VDPAU API), it is only supported by the proprietary Nvidia driver on Linux. Application and library s ...

Nvidia Quadro
Quadro was Nvidia's brand for graphics cards intended for use in workstations running professional computer-aided design (CAD), computer-generated imagery (CGI), digital content creation (DCC) applications, scientific calculations and machine learning. Differences between the professional Quadro and mainstream GeForce lines include the use of ECC memory and enhanced floating point precision. These are desirable properties when the cards are used for calculations which, in contrast to graphics rendering, require reliability and precision. The Nvidia Quadro product line directly competed with AMD's Radeon Pro (formerly FirePro/FireGL) line of professional workstation cards. Nvidia has moved away from the Quadro branding for new products, starting with the launch of the Ampere architecture-based RTX A6000 on October 5, 2020. To indicate the upgrade to the Nvidia Ampere architecture for their graphics cards technology, Nvidia RTX is the product line being produced and developed m ...

HEVC
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 (AVC, H.264, or MPEG-4 Part 10). 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. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses integer DCT and DST transforms with varied block sizes between 4×4 and 32×32. The High Efficiency Image Format (HEIF) is based on HEVC. , HEVC is used by 43% of video developers, and is the second most widely used video coding format after AVC.

Bandicam
Bandicam (stylized as BANDICAM) is a closed-source screen capture and screen recording software originally developed by Bandisoft and later by Bandicam Company that can take screenshots or record screen changes. Bandicam consists of three main modes. One is the Screen Recording mode, which can be used for recording a certain area on the PC screen. The other is the Game Recording mode, which can record the target created in DirectX or OpenGL. And the last is the Device Recording mode which records Webcams and HDMI devices. Bandicam displays an FPS count in the corner of the screen while the DirectX/OpenGL window is in active mode. When the FPS count is shown in green, it means the program is ready to record, and when it starts recording, it changes the color of the FPS count to red. The FPS count is not displayed when the program is recording in the Screen Recording mode. This software has a maximum frame rate of 144 FPS. Bandicam is shareware, meaning that it can be tested fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Coding Engine
Video Code Engine (VCE, was earlier referred to as Video Coding Engine, Video Compression Engine or Video Codec Engine in official AMD documentation) is AMD's video encoding application-specific integrated circuit implementing the video codec H.264/MPEG-4 AVC. Since 2012 it was integrated into all of their GPUs and APUs except Oland. VCE was introduced with the Radeon HD 7000 Series on 22 December 2011. VCE occupies a considerable amount of the die surface at the time of its introduction and is not to be confused with AMD's Unified Video Decoder (UVD). As of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN). Overview The handling of video data involves computation of data compression algorithms and possibly of video processing algorithms. As the template compression methods shows, lossy video compression algorithms involve the steps: motion estimation (ME), discrete cosine transform (DCT), and entropy encoding (EC). AMD Video Cod ...
