|a=FLICKER(seed, prob(1/X), max, min)|
|Items in CAPS are 0/1 switches or switches with more options than 0/1.|
This is the seed for the random number generator. Using the same seed will provide repeatable results.
This is the probability that the frame will flicker. You can think of the value entered as "The film will flicker every THIS MANY frames, on average." A value of 1 will insure that the frame will flicker every time. A value of 100 would mean the film only flickers every 100 frames, on average.
This is the maximum percentage change that the film can flicker. A value of 100 would mean that the brightness can change up to double its current brightness. This value can be negative, it means that the frame will darken.
This is the mimimum percentage change that the film can flicker. A value of 10 would mean that the brightness can change to no less than 110% its current brightness. This value can be negative, it means that the frame will darken.
Some of the controls have a Trend button next to them. These trend buttons allow you to set variables over a series of frames. Each frame of any animation may be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Trend graphs have equidistantly spaced vertical lines. For animations under 100 frames in length, each of these lines represents a frame in the animation. The number of frames in any one sequence can be altered using the Sequence controls item from the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.
