总结:h265压缩率并非传说中的比h264高50%,h265压缩1080p视频能小20-30%左右,720P视频能小15%-20%左右,h265要达到比和264高50%压缩率除非视频分辨率达到4k。nvenc压缩的视频相同画质情况下比h264中速压缩的视频要大10% 4楼2019-08-24 09:21 收起回复 啃烧饼的龙 初三年级 12 不同版本不同预设的x265...

@bradleyseposInteresting. Thanks for the link. I'm seeing a 30x performance difference (yes, 30 times faster) with NvEnc H.264 vs software x264, so my results definitely don't agree. My tests with H.265 are even more dramatic in favor of NvEnc. ...
自带的编解码比核显好用,尤其是编码快。同等级别的剪映编码,H265/H264比UHD630核显快3倍左右。 游戏性能,也能凑合用。下能玩Switch模拟器,上能玩VR游戏ALYX。 跑AI绘图,拥有4GB显存,可以运行。 这代支持DP1.4和HDR,也就是说,能够兼容新的显示器做观影用。使用核显UHD630,是无法支援HDR显示器工作的。
video. For each of these conversions, I used identical settings except I changed the Constant Quality option in HandBrake. Each of these used the H.265 (NVenc) encoder with all the other video options on their default settings. Each conversion took about 1 hour (give or take 10 to 15 ...
