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 高一年级 13 不同版本不同预设的x265...

It's not a constant bitrate. Constant bitrate doesn't EXIST AT ALL in H264/H265 codecs. The bitrate is always variable (VBR). So you don't have to try to "avoid Constant QP". It's NOT "constant bitrate". It's "Quantization Parameter", which is simply a parameter that decides ho...
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 ...
