Try changing the second line to:

[Math.min(temp,100),100];

Seems like this should work:

x = 764 – (100 – comp(“MAIN”).layer(“CONTROLLER_PercentTargets”).effect(“Slider 1”)(“Slider”))*(764-112)/100;
Math.min(x,764)

Try this:


n = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time) n--;
}
if (n > 0){
time - marker.key(n).time + framesToTime(parseInt(marker.key(n).comment,10));
}else
0

Play around with this:


seedRandom(index,true);
tStart = 2;
dur = .8;

myStart = random(tStart);
t = time - myStart;
if (t < .5*dur)
ease(t,0,.5*dur,[0,0],[120,120])
else
ease(t,.5*dur,dur,[120,120],[100,100]);

The only thing I can think of would be a hack, but it might be useful. You could have a source text expression like this:

if (time < 0)
“your_extra_long_word_goes_here”
else
value;

Then you could use sourceRectAtTime() with a negative time to get the width of just that word. Then I’m not sure what you do, but hopefully that’s useful…

Try it this way:

clamp(transform.scale,[45,45],[85,85])

Varying the hold time will mess up the entire expression, so you would need to go to a more cumbersome model, like this:


easeTime = .2;
minHoldTime = .1;
maxHoldTime = .5;

seg = 0;
segStart = inPoint;
curT = inPoint;
while (curT <= time){
seedRandom(seg,true);
holdTime = random(minHoldTime,maxHoldTime);
period = easeTime+holdTime;
segStart = curT;
seg++
curT += period;
}
t = time - segStart
amt = 36;
(seg-1)*amt + ease(t,0,easeTime,0,amt)

If you’re using a text file, the numbers start out as text, correct? So (I.m guessing) your expression must be using parseInt() or parseFloat() to convert the text to a number. If so, you can use isNaN() after the conversion to see if it actually created a number. Like this:

n = parseFloat(yourText);
if (isNaN(n)) n = 0;
n

What does the expression that’s controlling the opacity look like?

I can’t think of anything an expression could access that would be unique for each AE launch. You do get that automatically with scripting though, so I guess you could have a simple script populate a slider with a random number and use that as the random seed for your expression, but you’d have to remember to run the script each time you launch AE.
