gh5拍摄的原始422 10bit all-i视频
mediacoder
ShanaEncoder
adobe media coder cc2018
这三个都试过了，x264/H264都只能转出420 10bit
mediacoder手动指定配置文件为hi10/hi422/hi444，等级手动5.1，都没用（auto就更不用说了）
ShanaEncoder只能指定hi10配置文件
adobe media coder cc2018和mediacoder一样手动指定配置文件和等级，勾上用最大色深渲染，也没用……

--output-csp i422

shanaencoder x265/HEVC 可以加参数-pix_fmt yuv444p 、-pix_fmt yuv422p 、-pix_fmt yuv420p
10bit 8bit都行。
x264 -pix_fmt yuv422p10 -f mkv -c:v libx264 -c:a libfdk_aac -crf 19.0 -profile:v high422 -level 5.1 -preset medium -tune:v none -b:a 128k -fdkprofile he -ac 2
即是yuv422 10bits同理yuv444 8bit就去掉yuv420后面的p10

一定要注意-profile:v high422你设置其他后，这个变为baseline就会出错，记住是在F8参数设置xml里改

我一般420或者444……

ffmpeg -i src.mkv -pix_fmt yuv422p10le -c:v libx264 -profile:v high422 -crf 19 -c:a copy target.mkv
FFmpeg真的是，好用到爆，我TM吹爆

ffmpeg画质没有hanbrake的好

我用格式工厂导出 直接变成444 10bit了
