NVEnc can provide faster and more efficient video encoding than CPU-based encoders.I have tested several videos and with all of them the following error message appears towards the end of the conversion process and the video is not written correctly (there are always a few seconds missing at the end and the index - e.g. Ease of use: The encoder is easy to use, with a range of configuration options to allow users to customize the encoding settings.Software integration: The encoder can be integrated into existing software packages with minimal effort, allowing it to be used in a wide range of applications.Scalability: The encoder can scale from low-bitrate 720p up to 8K resolution.

High-performance encoding: The encoder is optimized for high-performance encoding, allowing it to encode multiple video streams in parallel with minimal impact on CPU utilization.Low-power performance: The encoder is designed for low-power consumption, enabling the encoding of high-resolution video streams without the need for a powerful processor.Low-latency performance: NVENC enables low-latency video encoding and decoding, which is essential for applications such as video conferencing, streaming, and gaming.The encoder can encode up to 8K resolution video streams with a maximum bitrate of 16 Mbps. High-quality encoding: The NVENC encoder supports the H.264 and HEVC/H.265 video codecs, which are widely used for recording and streaming video.The technology enables the encoding of high-resolution video streams in real time, while still providing an excellent quality-to-file size ratio.

NVENC can be used for a variety of different applications, including video streaming, video conferencing, gaming, and more. It provides a fully-enclosed, end-to-end encoding and decoding solution that delivers low-latency and low-power performance for a wide range of applications. NVIDIA Encoder (NVENC) is a feature in NVIDIA graphics cards that enables the hardware-based video encoding and decoding of the H.264 and HEVC/H.265 video formats.
