this might work, it’s another way to orient to path.
the box you want to orient to null’s bezier path looks like this.

//position data
thisComp.layer(“Null 1”).transform.position

//rotation data
v=thisComp.layer(“Null 1”).transform.position.velocity;
radiansToDegrees(Math.atan2(v[1],v[0]))

//////////

if that doesn’t work, you’ll have to use a dummy system.
name your rectangle “box” and paste this in rotation of the arrow. this will always auto orient to the layer being called to.

follow2 = “box”
diff = sub(position,this_comp.layer(follow2).position);
(Math.atan2(diff[1],diff[0]) * 180/Math.PI) + 180

cc light burst, radial zoom, blurs, etc.. there’s load of ways. just watch all these tuts.

updated a small bug.
dur = Math.floor(thisLayer.outPoint-thisLayer.inPoint);
and then I realized beginCount = 25; /which needs to be fixed.

I took the liberty to update Dan’s expression for you. It will count as fast as the text layer is long in the project, so just size the text layer as needed. Also, you’ll want to go to paragraph-right align text.


numDecimals = 0;
commas = true;
dollarSign = false;
beginCount = 0;
endCount = 24698526;
dur = Math.floor(thisLayer.outPoint);

t = time - inPoint;
s = linear (t, 0, dur, beginCount, endCount).toFixed(numDecimals);

prefix = "";
if (s[0] == "-"){
prefix = "-";
s = s.substr(1);
}
if(dollarSign) prefix += "$";

if (commas){
decimals = "";
if (numDecimals > 0){
decimals = s.substr(-(numDecimals + 1));
s = s.substr(0,s.length - (numDecimals + 1));
}
outStr = s.substr(-s.length, (s.length-1)%3 +1);
for (i = Math.floor((s.length-1)/3); i > 0; i--){
outStr += "," + s.substr(-i*3,3);
}
prefix + outStr + decimals + " m";
}else{
prefix + s+ " m";
}

The warp layer is usually a better version of the original footage, if you read the help file it says so. reading the foundry’s kronos pdf gives more detail about local estimation. i tricked timewarp into using a whole different frame to warp the fields together.

The lower field shouldn’t get motion blurred if the motion blur is off, but in low quality footage with small details, sometimes turning off the warp layer improves the antialiasing creating really really nice deartifacting capabilities. yes, the upper field is timestretched at 50%.
There’s no timeremapping. and ww1 footage has fields off.

another feature is fps changing. if you change the final output comp to a new framerate, it will automatically interpolate eg 23.976 film look from 59.94 fields/sec. as long as you match the timestretch of the 2comp and timewarp comp, you can trade smoothness for artifacts. they cancel each other out.

as far as I know, you can’t access the individual points of particular.
you can always wiggle solids in 3 dimensions, then write a quick script or expression that attaches each 3d point as ends to the beam.

it would be pretty easy because the solids are circular to begin with so you don’t have to worry about angles.

also, I haven’t tried this, but what if you duplicate your particular comp and have one with trails on with smaller size and one with trail off with larger size. I don’t remember how particular creates it’s randomness code so this may or may not work.

omg…once again, I over-complicate things…simply use time as a timeremap

x= effect(“Slider Control”)(“Slider”); // turns 50% into timestretch 50%
x=x/25;
time*x;

that isn’t confusing..ha! well I believe what you what is simply re-import another copy of your project into itself then drag the comps out you need again. also aescripts has a comp to project script.
