Mistika 的前身叫：Jaleo，这个西班牙的软件目前仍然是最受好评的广告和电视剪辑软件。因为支持著名的5Dbox，所以它的特效功能也一点也不落伍。特别是JaleoHD版本，可以支持长片的多轨道高清实时剪辑和合成。所以北京和广州的很多作MTV、广告、电视剧、数字电影的后期公司仍然在使用它。在后期软件中间，Jaleo的剪辑和实时效率，仍然是剪辑师中口碑最好的！现在我们有了 新的软件名字叫Mistika。

Mistika作为一套后期高端实时全功能系统，能做到在所有剪辑、特效、调色及立体影像制作过程中采用4K非压缩全实时在线制作，即所谓的“所见即所得”，不使用代理画面通过显卡预监显示的调色。

cmiVFX Mistika Advanced Channel Keying

For over 15 years, node-based compositing applications were the backbone of a film pipeline. These days, we rely on procedural-based software to create both visuals and audio effects in just about any creative industry. To better assist the art of color correction and keying, a method of channel extraction was created called “Maynard Keying” (Sometimes known as M-Key or Modular Key). This workflow relied on node-based software exclusively in order to achieve the goal of combining various channels into solid-object extractions which would work with semi-transparent areas. Many keyer tools have come a long way since the beginning. In some cases they can handle an entire key all by itself without needing to do any extra work. The problem that still exists is that not all shots have good lighting and reduced noise.
