What is SSATool?
SSATool is a utility designed to help create Advanced Substation Alpha (SSA) scripts. Various utilities such as time shifting are available, as well as more advanced effects generators like karaoke and gradients.

What do I need to run it?
As of version 3.0, SSATool is programmed C#, which requires the Microsoft .Net framework. Currently, I am using 2.0, so you will need the 2.0 framework, available from Microsoft here. There is ongoing work to make an open source version of .Net (Mono), which you may try if you don't use Windows.
