Note that Baseline Profile, such as that used by iPods, does not support B. Command line reference. 2,and I use command line to encode with hevc_nvenc,it works ok. Setting frame rate (in picture / frame rate) doesn't seem to do anything (all resulting clips are 25fps). The only real downside is that at lower bitrates, NVENC isn’t quite as crisp as x264, especially for fast moving games. Search for local Photographic Processing & Printing near you on Yell. TU117 is an interesting lower power part that could be useful as a single slot card, esp for htpc. Default value is 0. Similar to the consumer GeForce GTX 1060 (Laptop), it is based on the GP106 chip with. For low motion content (i. Some remote desktop solutions produce intermixed frames and because of fade-out and fade-in-effects, some frames will not provide a clear reading. It's a physical section of our GPUs that is dedicated to encoding only. keyint=15 - This is setting the maximum interval between keyframes to 15 frames. 1 (trước đây là OBS Multiplatform) là phần mềm ghi và stream video trực tiếp, hiệu quả. Setting it to 0 will let driver use the default dpb size. We have found that much of the quality issue with Hardware Accelerated encoding is due to it being limited to ~60mbps. Suggestions range from silencing the console to applying the "fps=xxx" filter, but when I apply the fps filter it adds stutter to my video, and silencing my console isn't really an actual solution as I lose visibility of everything else.
