![]() Needless to say, it always massively outperformed h264_nvenc in terms of quality for a given bitrate, while also being slightly faster. Using the 'slow' preset, av1_nvenc outperformed hevc_nvenc in terms of encoding speed by 75% to 100% while performing above tests. It produces fewer artifacts and the ones it does produce are less jarring to my perception.Īt higher bitrates I had a hard time finding differences between the two encoders in terms of subjective visual quality. GIF/WebP/AVIF creation, and more ffmpeg mp4 webp mkv hevc x264 x265 hdr vp9. In terms of quality at low bitrate cbr settings, it seems to outperform it even. Thats why using NVENC allows you to play games at a higher framerate and. The encoder seems to be trading blows with hevc_nvenc. ffmpeg -strict 2 -hwaccel auto -i 'inputfile.mp4' -c:v hevcnvenc -rc vbr -cq 24 -qmin 24 -qmax 24 -profile:v main10 -pixfmt p010le -b:v 0K -c:a aac -map 0 'outputfile. Use the following command to obtain a list of all NVIDIA GPUs in the system and their corresponding ID numbers: ffmpeg -vsync 0 -i input.mp4 -c:v h264nvenc -gpu list -f null Once you know the index, the -hwacceldevice index flag can be used to set the active GPU for decoding and encoding. Timo Rothenpieler merged the NVENC AV1 encoding support and summed it up as: This is the setting I use for NVENC HEVC on Turing cards. It has become most important and widespread codec in the industry. ![]() This weekend, FFmpeg added support for using NVENC AV1 with the new NVIDIA GeForce RTX 40 series cards. NVENC and NVDEC can be effectively used with FFmpeg to significantly speed up video decoding, encoding, and end-to-end transcoding. NVENC Performance Test Setup H.264 emerged 15 years ago and has become an ubiquitous video coding standard. Using the FFmpeg variant does not improve quality, so it is enough to use the built-in encoder for. ![]() ![]() With the Intel Arc Graphics, AMD Radeon RX 7000 series, and NVIDIA GeForce RTX 40 series, GPU-accelerated AV1 encoding is now widely available for this royalty-free video codec that is becoming more and more popular. If you have an NVIDIA GPU, set the Encoder to NVENC. ![]()
