Damn… I appreciate your help a LOT anyway, dude, you’re awesome.

I’ll try to explain again in case of someone else shows up…

The idea is to be able to control the time remap randomness as an effect, turning it on and off whenever I need.

So it would begin with a specific still frame, then I would turn the ‘effect’ on to make it begins to change the frames randomly and then turn it off back to the specific still frame.

I think it would be better with expressions because otherwise I’ll have to make 3 layers, the first with the specific still frame, the second with expression changing the frames randomly, and then a third layer with the specific still frame.

Damn, sorry for that.

Now it’s working, with the sliders on!

I set them to 0/0 and when I want it to start, I keyframe it to 1/3.

But it’s not looping the frames, it just plays once.

Just to summarize it, I’d like to control in keyframes the start and stop points to the frames begin to change randomly in loop mode and then stop whenever I want.

Yea, the ideia is to be able to control the time remaping expression starts and stops.

I tried to isolate the layer in a new comp to make tests and now when I use this expression, I get an error message:

Error at line 3 in property ‘Time remap’ of layer 1 (‘C 2’) in comp ‘teste’.
Expected: ).

tStart = 1;
tStop = 3;
if (time > tStart && time < tStop){
t = time - tStart;
frameDur = 15;
f = timeToFrames(t);
seg = Math.floor(f/frameDur);
seedRandom(seg+1113,true);
rf = Math.floor(random(3));
framesToTime(rf)
}else 0

When I’m using this expression linked to sliders, nothing happens, even when I set them to 1 and 3, like you said… 🙁

tStart = effect("Slider Control")("Slider");
tStop = effect("Slider Control 2")("Slider");
if (time > tStart && time < tStop){
t = time - tStart;
frameDur = 15;
f = timeToFrames(t);
seg = Math.floor(f/frameDur);
seedRandom(seg+1113,true);
rf = Math.floor(random(3));
framesToTime(rf)
}else 0

[Rafael Braz]

When I paste this code on time remap, it works just as I want it.
But what I’d like to do is to control when this expression starts and ends, otherwise I’ll have to split all layers in order to control it.
I’m sorry if I wasn’t clear.
Thanks a lot for your support, though.

tStart = 1;
tStop = 3;
if (time > tStart && time < tStop){
t = time - tStart;
frameDur = 15;
f = timeToFrames(t);
seg = Math.floor(f/frameDur);
seedRandom(seg+1113,true);
rf = Math.floor(random(3));
framesToTime(rf)
}else 0

[Rafael Braz]

Yea, I tried 1, 3, or 0.01, 0.03, I dragged the slide all the way but nothing happened… :/

[Rafael Braz]

Nothing happens 🙁

[Rafael Braz]

Thanks a lot dude, I just had the opportunity to test it today.
How do I exactly do it?
I tried to paste the expression on both Slider and Time Remap, but I’m confused on how to relate them.

[Rafael Braz]

It works dude!!!! Thanks!!!!

Would it be too much to ask you how to make a slider or something to turn it on and off? So I can choose when I want the randomness to start and end?

[Rafael Braz]

Actually, this 3 years old expression I found works perfectly, but, I don’t know why, one of the frames is BLANK!
Why’s that for god sake? :`(

numFrames = 5;
minDur = 15;
maxDur = 30;

f = timeToFrames();
f0 = 0;
seedRandom(index,true);
while (f0 <= f){
f0 += Math.floor(random(minDur,maxDur+1));
}
seedRandom(f0,true);
framesToTime(Math.floor(random(numFrames)));
