【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.

1.1.2 更新内容：* Crash bug fix* ProRes bugs fixes* Added a “AfterCodecs AV Muxing” Dialog at the end of the render* Added encoder metadata to ProRes with AfterCodecs’ and ffmpeg’ version (for example “ProRes HQ (AFC 1.1.2 3.2.2)”)This info can be seen in AE and PP* Added fast decode for x264 / x265 when resolution > HD* In the preview text under “Format Options” little description of chosen encoding parameters (for example “x264 Q75 (Streaming)”)* The encoding window is not always on top anymore* Prevents overwriting files with the same name before launching render, asking to rename the file OR overwriting OR cancel the render支持Win系统：After Effects CC 2014 – CC 2017
