![]() ![]() Introduced with the first-generation Maxwell architecture, second generation NVENC adds support for the high-performance HP444 profile (YUV4:4:4, predictive lossless encoding), and increases encoder throughput up to 16× realtime, which corresponds to about 1080p 480 Hz with the high-performance preset. The high-quality preset is considerably slower but produces fewer compression artifacts Second generation, Maxwell GM107 The published 8× rating is achievable with the NVENC high-performance preset, which sacrifices compression efficiency and quality for encoder throughput. Actual throughput varies on the selected preset, user-controlled parameters and settings, and the GPU/memory clock frequencies. NVidia's documentation states a peak encoder throughput of 8× realtime at a resolution of 1920×1080 (where the baseline "1×" equals 30 Hz). ![]() The first generation of NVENC, which is shared by all Kepler-based GPUs, supports H.264 high-profile (YUV420, I/P/B frames, CAVLC/CABAC), H.264 SVC Temporal Encode VCE, and Display Encode Mode (DEM). (In H.264, NVENC always has B Frame support, max 4096x4096 resolution, and max 8-bit depth) NVENC has undergone several hardware revisions since its introduction with the first Kepler GPU (GK104). Nvidia chips also feature an onboard decoder, NVDEC (short for Nvidia Decoder), to offload video decoding from the CPU to a dedicated part of the GPU. , the restrictions were loosened in 2023 allowing up to 5 simultaneously encoding video streams. Professional cards support between 3 and unrestricted simultaneous streams per card, depending on card model and compression quality. 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. Until March 2023 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. It also works with Share game capture, which is included in Nvidia's GeForce Experience software. ![]() 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 was introduced with the Kepler-based GeForce 600 series in March 2012. ![]() Even if you look away from the camera, the AI will create the illusion you're still looking the right way.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. Maxine Eye Contact - this tool uses artificial intelligence to make it look like you're constantly maintaining eye contact during video calls, live streams or recordings.Whether that's dogs barking in the distance or the hum of your air conditioning, Nvidia Broadcast promises to make your voice clearer and your stream more professional. Noise removal - this app also includes an improved version of RTX Voice, which uses AI to actively remove background and environmental noise from your microphone.Thereby overlaying your camera feed over game footage without having to faff about with green screens. At a basic level, you can simply blur your background but you also add custom virtual backgrounds and even create green screen effects without a green screen. Virtual backgrounds and blurring - Nvidia Broadcast offers the ability to adjust the background of your camera's view in a similar way to what you've probably already seen with Zoom, Skype and other apps.Nvidia says this is like having your own cameraperson and ensures you're always at the centre of the action. Auto framing - using artificial intelligence, the app can track your movements, meaning it'll follow you around the room if you're moving about within the field of view.Nvidia Broadcast offers various useful features that include: ![]()
