不知道在哪个版本的时候SSS突然发现After Effects 的MP4格式无法输出了，原来ADOBE为了与软件之间的流程化工作，所有去掉了AE内部的H264的编码，转而发送到Media Encoder中进行渲染，相关的不稳定信还是很大的，所有此编码器插件就开发出来了。
不是经常用这个插件，为什么呢，一是流程化的工作太重要了，在AE软件中直接输出一个是耽误制作时间，二是在AE中直接输出比在Media Encoder中输出机器卡太多了，所以自由的选择。
AfterCodecs v1.5.0更新日志：
1.5.0 (Current version) – Oct 20, 2018
* Updated for CC 2019
* Our ffmpeg fork executable is now called ffkroma, don’t forget to update if not using the Windows installer ! AfterCodecs needs at least version 4.0.2-93
* HAP codecs improvements :
– New Hap Q Alpha profile ! Automatically selected when rendering “Hap Q / Hap Q Alpha” and exporting an alpha channel (“RGB + Alpha” in AE, checkbox in PPro / AME)
– Best quality : new HAP algorithms are equivalent in quality to original Vidvox / Quicktime algorithms
– Faster compression : those algorithms were optimised with fast processor instructions, including AVX512 for recent workstations, and multithreading (up to 3 times faster depending on your content and configuration)
– For Hap and Hap Alpha you have the choice between 3 methods of compression, each with their own tradeoff between speed and quality
– Multiple By 4 Resolutions in HAP limit removed, you can now render any resolution you want
* Warning on OSX : Adobe changed their way of interpreting AfterCodecs ProRes 422, it has now a color shift on reimport in Adobe CC 2019 (only), please use ProRes 4444
* Unable to Undo (CTRL+Z) when using automatic AE RQ Comments bug fix, now this feature has its own sub menu in “Composition” top menu under “AfterCodecs Settings”
