[2][3] 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.
[10] (In H.264, NVENC always has B Frame support, max 4096x4096 resolution, and max 8-bit depth) 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).
NVidia's documentation states a peak encoder throughput of 8× realtime at a resolution of 1920×1080 (where the baseline "1×" equals 30 Hz).
Actual throughput varies on the selected preset, user-controlled parameters and settings, and the GPU/memory clock frequencies.
The published 8× rating is achievable with the NVENC high-performance preset, which sacrifices compression efficiency and quality for encoder throughput.
The high-quality preset is considerably slower but produces fewer compression artifacts 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.
It supports HEVC 8K, 4:4:4 chroma subsampling, lossless encoding, and sample adaptive offset (SAO).
Nvidia Video Codec SDK 8 added Pascal exclusive Weighted Prediction feature (CUDA based).
The initial launch of the Nvidia GeForce GTX 1650 was exempt from this generation however, as it used Volta NVENC instead of Turing.
Nvidia announced the next-gen NVENC with 8K 10-bit 60FPS AV1 fixed function hardware encoder in Ada Lovelace GPUs.
