In this Episode of Red Giant TV, Aharon Rabinowitz shows you how to create the look of Filmed computer screen (what it looks like when you film it with a handheld camera) using After Effects and elements created with screen capture software.
Expression for Creating Wiggle with Ease:
freq=.5; //frequency: fill in or tie to a slider
amp=30; //amplitude: fill in or tie to a slider
octaves=1; //default value
amp_mult=0.5; //default value
period=1/freq; //time taken for each wiggle move
pCount=Math.floor(time/period); //number of wiggles performed so far
sTime=pCount*period; //time when current wiggle begins
eTime=pCount*period+period; //time when current wiggle ends
p1=wiggle(freq, amp, octaves, amp_mult, sTime); //start position of current wiggle
p2=wiggle(freq, amp, octaves, amp_mult, eTime); //end position of current wiggle
ease(time, sTime, eTime, p1, p2); //ease the wiggle

Hmm…it looks like things are taking a while to load. Try again?
