Perhaps add a very large, slowly evolving Fractal Noise on top of it in Overlay or softlight noise, that gradually fades away, to make it a bit less linear and uniform.

Hi,

this is a bit different from Dan’s example wich uses random directions I believe.
A true-er pong motion if you will: ingoing angle is always the same as outgoing angle. Like those really old windows screensavers.
change the values in the first three lines.

apply expression to position-param:

box=[20,20,300,220]; // box you want to stay in [x1,y1,x2,y2]
motion=[312,123]; // motion-vector in pixels per sond [x,y]
startpos=[160,120]; // startposition

// calculations:
w=box[2]-box[0]; h=box[3]-box[1]; corner=[box[0],box[1]];
delta=motion*time; pos=startpos+delta-corner;
xx=pos[0]%(w*2); yy=pos[1]%(h*2);

corner+[xx

D’oh !

I’m so stupid, the calibration in the effects window follows the one you set in the info window!
click on little arrow on the right-hand side of the info window and you can choose color-display as percentage, Web, HSB, 8bpc etc.

I don’t think you can

[Filip Vandueren]

set your property (opacity ?) to 50%
then add this expression:

o=wiggle(1, 50, octaves = 1, amp_mult = .5, t = time); // this is just a basic wiggle, amp set to 50
o<50?0:100;


the last cryptic line is shorthand for [if o is less than 50, give 0, else give 100]

Forget about it 😉

It’s a nice effect and I had thought about it before;
I just need someone else to get me going before I go and find a solution 😎

By The way, I think you get the best effects when you use something like 10 ms, and maybe 2 pixels instead of 1.
As I said with frame-blending enabled (if it’s a video layer, if it’s a pre-comp you need to enable the frameblending there.)
You can use positive or negative values to get a different effect, and the vertical sometimes gives way better results.
Depends on the motion.

I look forward to seeing your final movie if you can upload it somewhere ?

Clever 😎

BIt simpler than mine, haha
