AE - Stopmotion and Jitter Jitter

//by Steve Roberts ad Creativ COW


For Frame rate use:

time>posterize

--------------------------------------------------------------

And for jitter:

t=time+random(.1);
valueAtTime(t)

or more Tweaks


t=time+random(.09,.2);
valueAtTime(t)

AE - Opacity -Dealy form Index layer

//(hacked) form a Dan Ebberts expression.

http://www.motionscript.com/mastering-expressions/follow-the-leader.html

delay = 10; //number of frames to delay
op = thisComp.layer(index+1).opacity;
d = delay*thisComp.frameDuration;
op.valueAtTime(time - d)

AE - Sample color from image.

Source: http://www.motionscript.com/design-guide/sample-image.html


Can be used with fx: Fill (color) in the solid layer

target = thisComp.layer("background");
target.sampleImage(transform.position, [width, height]/2, true, time)

AE - link to another Comp Syntax

thisComp.layer("Rotating Lens Part").transform.zRotation+88.7*.673

becomes:

comp("name").layer("Rotating Lens Part").transform.zRotation+88.7*.673

comp("Sign").layer("Slave").transform.scale

AE - Position - invert position

//FROM VIDEO COPILOT
//Mylenium

pRef=thisComp.layer("Dot A").position;

X=thisComp.width-pRef[0];
Y=thisComp.height-pRef[1];

[X,Y]

AE - Particels - emit with markers

p = 9999; //number of particles to emit
fo = 7; //falloff time for emitting particles (in frames)
//(*falloff values less than 2 don't seem to emit any particles*)

m = thisComp.marker;

t = m.nearestKey(time).time;
