It would be a bit of work, but you could do it with a script. If it were me, I’d have the script build a separate comp for each location in the grid and randomly populate the sequence.

That’s the idea. 🙂

Glad to help.

Something like this:

dist = position[2] – thisComp.activeCamera.position[2];
linear(dist,4000,6000,100,0)

Is this what you’re looking for?

Animation > Keyframe Assistant > Convert Expression to Keyframes

In general, it would involve prompting the user to navigate to your text file, setting up a loop to read each line of the file until the end-of-file is reached, converting the text to floating point and creating a new position keyframe at the appropriate time (which, from your description, sounds like it would be the same as the line number).

It’s fairly straight-forward if you have some scripting exprerience. Unfortunately the learning curve for scripting is quite a bit steeper than it is for expressions.

I was afraid of that. 🙂

Something like this might work:

decayStart = 4;
decaySpeed = 4;
segMin = .3; //minimum segment duration
segMax = .7; //maximum segment duration
minVal = 0;
maxVal = thisComp.width;

end = 0;
j = 0;
if (time > decayStart){
  delta = time - decayStart;
  factor = 1 + delta*delta*decaySpeed;
}else{
 factor = 1;
}
while ( time >= end){
  j += 1;
  seedRandom(j,true);
  start = end;
  end += random(segMin,segMax)*factor;
}
endVal =  random(minVal,maxVal);
seedRandom(j-1,true);
dummy=random(); //this is a throw-away value
startVal =  random(minVal,maxVal);
y = position[1];
ease(time,start,end,[startVal,y],[endVal,y])
