PD Pro 4 Tutorials

	Here's another set of tools: In the 'Other FX' category, where various special effects can be found. The animated threshold uses something like the threshold filter and interpolates the parameter from 0% to 100%
	Animated flicker uses two colors, as set by the primary and secondary colors of project dogwaffle. The filter renders these colors, alternating between the two from one frame to the next. The Strength can also be adjusted.
	This is a quick way to add a flickering or strobe-like effect as if looking at an old, interlaced cathode ray tuve or TV from the 1950's The primary and secondary colors were set to black and white.
	You can also specify a subrange, i.e. a start frame and an end frame for the effect to apply. Here we set the start at about frame 30 instead of frame 0. The last frame was around 80 instead of 120. Thus, the effect is not present for the first second and last second or so. Also, the Strength was set higher, causing a stronger alternation between bight and dark strobes.
	Or you can combine this with further processing in other FX filters. For example, in this example we used the Timeline editor from the Animation men u of PD Pro. In the VIdeo category of the Timeline filters, the "Video lines" effect was applied.
