Previous versions of this product were known as Knoll Lens Flare. I'm glad to see the name change, as Lens Flare alone under-values the myriad of possibilities that you have with Knoll Light Factory. It does much more than create a simple lens flare in a shot. For my tests, I used Knoll Light Factory in After Effects and also in Final Cut Pro. As I will discuss, certain elements work better in After Effects than in Final Cut Pro.
Installation is simple.
Inside are four installers. For FCP, or AE, launch the Knoll Light Factory installer. When you launch FCP, you will find the plug-ins in the Effects Tab of the Browser, under AE Effects. In After Effects, they are located under the Effects Menu. They consist of three main plug-ins, Light Factory, Light Factory EZ, and Light Factory Spectacular.
