Hey folks…

Okay, a bit weird answering my own question but I found a solution by Dan Ebberts! it is not 100% as a wished but rather 99% ????

Since I use sampleImage and a precomp/mask for the scaling animation, the idea with the sampleimage came in great and handy! Thank you Dan!!!

The solution is from this topic:

L = thisComp.layer("sampleLayer_A");
threshold = 0.00001;
trig = false;
ss = [width,height]/2;
for (f = timeToFrames(); f >= 0; f--){
t = framesToTime(f);
v = L.sampleImage(L.fromComp(toComp(anchorPoint,t),t),ss,true,t)[3];
if (trig && (v < threshold)) break;
if (v >= threshold) trig = true;
}
t = trig ? time - framesToTime(f+1) : 0;

Hi Sander!

The script is amazing! Thank you!
By the way, is it possible to prevent it from randomly have same colors at any given frame?

Let’s say I have 3 layers (L1, L2, L3) that get 10 random colors (C1, C2, C3, C4,…, C9,C10)
First change delivers L1->C4, L2->C8, L3->C10
Second change delivers L1->C2, L2->C4, L3->C9
Third change delivers L1->C5, L2->C5, L3->C7 (<—- here I would like to prevent the script from randomly giving out the same color twice (or even 3 times). Is it posible?)

Thank you!

Best regards
Emil

Hi Jacob,

Have a look at Dan’s solution, he uses Math.max:

Thank you Dave.

Unfortunatelly the customer doesn’t have any AFX knowledge (and the AFX setup isn’t that easy for a newbie.
So I guess we stick to the AFX solution and deliver a final video. :/

Wow, Dan!
This expression is amazing! Thanks so much! For my purposes I have even defined over 15 colors!

I have inserted it onto the Fill Effect (Color) of a Solid in a Comp named “Comp A”.
I also have Comp B, Comp C, Comp D, Comp E and Comp F with the same setup (Solid with the same expression mentioned). The expression works like a charm.

Is it howerer possible to tweak the expression(s) so that the random colors are NEVER the same at any given frame? The use the same pre-defined colors but are never the same. With seedRandom it probably doesn’t work, because it’s still randomness.

Thank you!
Emil

Thank you Kalleheikki,

That’s my suspicion, too. Unfortunatelly.
I don’t think it’s possible to “transfer” the corner pin data from AFX into AE directly, or? That would be a big help.

Best regards

The customer doesn’t have After Effects and I would like to deliver a kind of a template where he can just substitute the footage. Also possible with Essential Graphics?

Thank you!!!

[Emil Stefanow]

Hi Kalleheikki,

Thank you for the answer! ☺

How do I replace a AFX Solid with a footage in Premiere (not FROM Premiere but IN Premiere)?
Thank you!

Best regards
Emil

Hi,
Let’s say you have a comp with following 3 layers:

1. Text
2. videocomp_A
3. videocomp_B

You want that when people type in “A” in the essential graphics text field, then Videocomp A is visible, when people type in “B”, then Videocomp B, or?

Put the following code in the Opacity of videocomp_A:

myTextLayerContent=thisComp.layer("Text").text.sourceText.value;
if (myTextLayerContent == "A") 100 else 0

and for videocomp_B:

myTextLayerContent=thisComp.layer("Text").text.sourceText.value;
if (myTextLayerContent == "B") 100 else 0

Best regards
Emil
