x265不同preset下的参数集合
来源：互联网 发布：ug数控车编程软件 编辑：程序博客网 时间：2024/05/23 17:16
整理了X265不同Preset下的默认参数（仅作参考）
不同的Preset将直接影响编码的速度和解码后图像的质量，Preset级别越高，编码速度越慢，解码后的质量也越高；级别越低，速度也越快，解码后的图像质量也就越差，可以通过几下几个参数调节编码速度和解码后图像质量。其中最常见的参数
Coding QT: max CU size, min CUsize : 32 / 16 //设置CU的大小
x265 [info]: Residual QT: max TU size, maxdepth : 32 / 1 inter / 1 intra
x265 [info]: ME / range / subpel /merge : dia / 57 / 0 / 2 //表示运动估计的算法，运动估计范围，子像素搜索及其范围
x265 [info]: Keyframe min / max /scenecut : 25 / 250 / 0 //设置最大最小GOP及场景切换
