I tried your expression and found 2 flaws to it. It said that K1 is a function and it needed a number on line 22, and got out of reach for either markers or layers. So i modified it a bit. Tell me if it works, or what does’nt work, in case something is wrong. This is what i got
n= 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time){
n--;
}
};

prev = n;

next = (n>=marker.numKeys) ? marker.numKeys : (n+1);
K1 = prev;
K2 =next;

Val1 = thisComp.layer("val "+prev.toString()).text.sourceText;
Val2 = thisComp.layer("val "+next.toString()).text.sourceText;

T1 = parseInt(Val1.split(' '));

T2 = parseInt(Val2.split(' '));

U = marker.key(K1).time;

B = marker.key(K2).time;

TT = ease(time, U, B, T1, T2);

There is a script called iExpressions on aescripts.com . But has some costs to it. If you look for free information, i think your best bet is to google what you need and save it to your personal expression collection once you find it. And when you find something similar, but not quite what you need, you can always post on this forum and search for guidance.

One workaround would be to make a null and add a slider. And make the layer that the slider indicates visible, and the rest invisible. Something like this would fix the situation. In my case the layer is called “Controls” and the slider is called “Visible layer”. visibleLayer = Math.floor(thisComp.layer("Controls").effect("Visible layer")("Slider"));
if (visibleLayer == index) 100 else 0
The condition for this would be that your layers start at layer 1 and don’t have any other layers between them

I don’t really know what you ask. And how your start text look. You have something like “Starts Tuesday 6th March 9pm” and want it split, or you have multiple dates and want them split?

In the folowing expression the camera can not be parented as it will return the wrong value. You can use toWorld() or toComp() in that case(haven’t really used those, so i can not go in more detail). You put a null at the top of the bar and make it stay there. Then use this expression on your logo layers position. Modify mult until the position is the one you want. Mult should be the distance between camera and your logo. It is not my expression, I got it from here https://zacklovatt.com/points-along-a-line/

p1 = thisComp.layer("Camera").transform.position;
p2 = thisComp.layer("NullAtTopOfBar").transform.position;
mult = thisComp.layer("HELPER").effect("Distance")("Slider");

p1 + mult*(p2-p1)/length(p1,p2);

What if you reload the project after you replace the footage with a shorter one? Maybe it sticks to the duration in some kind of RAM way, like AE does with some variables used in scripts.

You will have to excuse my delay, i had to go to sleep and just got to the office right now. I have tested it with Dan’s expression and worked. The difference is that in my expression, i initiate the min with 0, which stays the minimum for all the duration. That is why it didn’t work. The big difference between Dan’s expression and mine is that his shows the value as it changes, while mine just snaps when getting to the keyframe. I recommend you try both. So for mine to work just change min initialization and use Math.mina =thisComp.layer("Shape Layer 1").transform.opacity
max = a.key(1).value;
for(i = 1;i<=a.numKeys;i++){
if (a.key(i).time <= time) max = Math.max(max, a.key(i).value);
}
max

Maybe the first value is tha absolute minimum… I have just tried it and it work on my side.

You should use Math.min instead of Math.max

This should not be so hard. Should look like thisif (layerProperty.expression == ''){ //the layer does not have an expression
layerProperty.expression = yourExpression;
}else{ //the layer already has an expression
expr = layerProperty.expression;
layerProperty.expression = yourExpression +'\n'+expr;
}

layerProperty should be the property you choose and yourExpression should be the expression you use. The ‘\n’ is used there as an empty line.
