After Effects Workspace

Here is an example of my typical After Effects workspace. I like to have my Project Files on the far left with the Effects Control Panel to the right of it. This allows me to select any layer from the Comp’s Timeline and immediately see the effects applied to the selected layer without having to manually open the Effects Panel. I also keep my Motion Tracking panel next to the Timeline and below the Effects and Presets so I can quickly enter into Motion Tracking mode.

Flicker Opacity Expression

//FLICKER OPACITY
blinkSpeed =10;
n = Math.sin(time*blinkSpeed);
if (n<=0) 0 else 100;

Oscillate Position on X-Axis Expression

//OSCILLATE POSITION BACK AND FOURTH ON X AXIS:
amplitude = 10;
frequency = 3;
temp=amplitude*Math.sin(time*frequency)+amplitude;
// add the result to the current x pos
temp=temp+transform.position[0];
//plug the new x into slot 0. y is currently left unchanged
[temp, transform.position[1]]

Make a Layer Bounce Expression

//MAKE A LAYER BOUNCE:
bounceSpeed=7;
flight=01;
bounceHeight=3.5;
t=Math.abs((time*2*bounceSpeed)%2-1);
t=linear(t,flight,0,0,1);
b=Math.cos(t*Math.PI/2);
value - [0,bounceHeight*b];

Flicker in to 100% Opacity Expression

//FLICKER IN TO 100% OPACITY:	
//Adjust this flicker frequency to your taste
flickerFrequency = 150;

op = value;
if(op > 0 && op < 100){
    reverseAmt=100-transform.opacity;
    wiggledAmt=wiggle(flickerFrequency,reverseAmt);
    roundedAmt=Math.round((wiggledAmt/100));
    roundedAmt*100;
}

Bounce on Marker Event Expression

//BOUNCE ON MARKER EVENT (put in scale):
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
}
if (n == 0){
value;
} else {
max_dev=20; // max deviation in pixels
spd=20; //speed of oscillation
decay=6; //how fast it slows down
t = time - marker.key(n).time;
s = max_dev*Math.sin(spd*(t))/Math.exp(decay*t);
value + [s,s];
}

Pendulum Swing Expressions

//PENDELUM SWING:
veloc = 10;  //how fast it swings
amplitude = 50;  //how high
decay = .999;
amplitude*Math.sin(veloc*time)/Math.exp(decay*time);
————————————————————————————

//PENDULUM SWING ON MARKER EVENT(put in rotation):
n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
}
if (n == 0){
value;
} else {
veloc = 10;  //how fast it swings
amplitude = 100;  //how high
decay = 4;
t = time - marker.key(n).time;
s= amplitude*Math.sin(veloc*t)/Math.exp(decay*t);
value + s;
}

Oscillate Layer in an Elipse Expression

//OSCILLATE LAYER IN AN ELLIPSE:
//Custom Adjustments:
radiusDistX = 30;  //set to zero for up/down oscillation
radiusDistY = 100;  //set to zero for sideways oscillation
period = 1; 
// DON'T ADJUST
value + [Math.sin(time*period)*radiusDistX,
-Math.cos(time*period)*radiusDistY]

Add $ and Comma at thousandth place Expression

//ADD A “$” AND “,” AT THE THOUSANDS PLACE ONLY:
//ADD SLIDER CONTROL TO TEXT
v="$"+Math.round(effect("Value")("Slider").value);
if (v.length > 3){
v.substr(0, v.length -3) + "," + v.substr(-3);
}else{
v
}

Load External .TXT in AE Text Layer Expression

//CALL EXTERNAL .TXT FILE TO LOAD IN AE TEXT BOX
try{
myPath = "~/Desktop/source.txt";
$.evalFile(myPath);
eval(thisComp.name)[0];
}catch(err){
"MISSING";
} 

//SCRIPT TO PLACE IN .TXT FILE
var comp1 = ["Text 0", "Text 1", "Text 2"];
var comp2 = ["Text 0", "Text 1", "Text 2"];
var comp3 = ["Text 0", "Text 1", "Text 2"];
var comp4 = ["Text 0", "Text 1", "Text 2"];
