It's about the same file size and NVENC renders very quickly. Each conversion took about 1 hour (give or take 10 to 15 minutes). In the end, just hit the green Start Encode button, and then HandBrake GPU encoding will start. X265 uses more time but produces vastly smaller files at NVENC vs x264 vs QuickSync. It will look the worst out of the three, but the difference in quality would be very little. If you want to stream 4K at 60fps, you’ll need a video bitrate range between 20,000–51,000 Kbps. GamersNexus Best Settings for Recording and Streaming - EposVox While NVENC delivers acceptable image quality, AMD does not. Adaptive quantisation in two modes using VAQ. However at a similar encoding time the picture quality of X264/5 quality is better compared to VP8/9. It wasn't unusable, without a doubt, yet NVENC used to eat a ton of subtleties. So an AV1 encoder with even better quality would have been nice addition.
264 is worse than x264 Medium and Slow, as well as Maxwell and Pascal NVENC. In x264 crf code, there are functions (ipratio & pbratio) where I-frame quantizer should be lower than P frame by 3 and B-frame quantizer should be higher than P frame by 2. AMF _ VCE on NAVI- Quality Analysis vs NVENC, X264 _ RX 580! RX 5700 _ RX 5700XT. x265 is an open-source HEVC encoder, originally ported These encoders produce H. 265/HEVC video encoder on Windows, Linux and FreeBSD, I decided to ask for guidance when it comes to compressing Anime (live action will follow at a later time) in the Doom9 forums. 265 (NVenc) encoder with all the other video options on their default settings. X264 faster is the usual compromise (quality vs latency) but with the 20 series cards Nvidia claim Nvenc at 6000kbit/s is equal to x264 fast, a setting that generally is too taxing on the cpu to use.
