Mewa Film User's Guide/Scripting
Mewa Film scripting offers the artist a huge creative freedom, not only by giving the ability to use a wide variety of expressions and script code directly within any parameter of the application but also by giving the ability to create scripts.
Scripts can be written for numerous purposes, one of the most common uses is the automation of a specific set of tasks.
An expression is any non-numeric entry, such as a variable or a mathematical expression. Any parameter can use an expression. Some expressions, such as time, are extremely simple. When you type the expression variable time into a value field, Mewa Film returns the numeric value of the current playhead position. For example, if the playhead (current time in player toolbar) is parked at frame 1, typing time into a value field returns a value of 1 in that field.
