【插件简介】AE软件虽然自带了很多输出格式选择，但是如果我们想输出特殊编码的时候，就需要借助其他工具，AfterCodecs 这款编码输出插件，就可以支持输出 H264，H265 和 ProRes 这些编码，渲染输出速度也比AE自带输出更快，且压缩的文件更小，画质更佳。

Native exporter for AE bringing you ProRes on Windows and h264 (x264 and x265) codecs for excellent quality and lightweight videos.

官网 http://aescripts.com/aftercodecs/支持渲染的编码：ProRes : LT / Proxy / Normal / HQ and even 444 that supports Alpha Channel.

x264 : best H264/AVC implementation, outperforming both Adobe Media Encoder, QuickTime H264 and AE’s built-in H264.

x265 : files are 30% lighter than x264 and it also supports 8K resolution.

x264 RGB : same as x264 but avoids YUV colorspace, best for storing separate channels in one video (UV map, Alphas…) for power users only.

1.2 更新内容：* Now macOS OS X compatible!* Two new plugins in the dropdown : “AfterCodecs .mp4″ and “AfterCodecs .mov”. There’s no more .ext and file renaming stuff (Removed the “Overwriting” options in Settings because not needed anymore)* You can choose ProRes 4444 Alpha depth now : 16 bits or 8 bits (smaller files, faster decompression)* Enabled lossless for x265 (same as x264 : 99 for 422, 100 for 444)* AfterCodecs will warn you if the width or the height are odd instead of displaying the generic error popup* 2 New shortcuts : ESC to exit AfterCodecs dialog, Shift+ESC to reposition it in the top left corner (use theses shortcuts if you have trouble with multiple screens for example)* ProRes 422 Bitrate matches more closely official Apple ProRes bitrate than before, and are now re importable back into AE on OSXBUGS FIXED :* Slight color shifts in ProRes has been mostly correctedWARNING :* Items in previous projects that uses AfterCodecs won’t be compatible with the new version, you’ll have to reconfigure them !* Windows : ProRes 4444 8 bits Alpha cannot be re imported in AE 16 bpc projects* OSX : ProRes 422 when re imported in AE CC 2014 and older have color shifts ! Everything is fine for CC 2015 and CC 2017支持Win系统：After Effects CC 2014 – CC 2017
