Guys, any hints? Am I tripping on expressions? 🙁

I just tried this as for in and out animations (100%/100% to specific and specific to 100%/100%)

t = thisComp.layer("PERGUNTA");
v1 = key(1).value;
v2 = key(2).value;
tRect = t.sourceRectAtTime(time,false);
tUL = t.toComp([tRect.left,tRect.top]);
tLR = t.toComp([tRect.left+tRect.width,tRect.top+tRect.height]);
myRect = sourceRectAtTime(time,false);
myUL = toComp([myRect.left,myRect.top]);
myLR = toComp([myRect.left+myRect.width,myRect.top+myRect.height]);
margin = 50;
linear(v1,[(tLR[0]-tUL[0] + 2*margin)/(myLR[0]-myUL[0]),(tLR[1]-tUL[1]+ 2*margin)/(myLR[1]-myUL[1])]*100,[(tLR[0]-tUL[0] + 2*margin)/(myLR[0]-myUL[0]),(tLR[1]-tUL[1]+ 2*margin)/(myLR[1]-myUL[1])]*100,v1);

Ok, I’ll try that! Thanks

Hey, Kevin, last question I guess.
I have a composition with a 30 min video that I applied the effect.
Before rendering, should I ram preview the entire composition?
I tried to render but the result failed, a lot of repeated frames, except the ones I had ram previewed.
It’s a little bit confusing, let me know if I’m not clear.

Thanks a lot, Kevin.
Your tips were awesome.
I re-downloaded AE 2014 and found the effect very useful.
As you made me aware of the CTI, I’ve being testing it so easily.
Also found this creative cow’s tutorial very useful:

I guess that’s all, thanks!!

[Rafael Braz]

Thanks, Kevin!
I’ll try that and then give you a feedback.
Just a quick question, what CTI stands for?

[Rafael Braz]

Well, I guess this video explains it all…

Apparently I should use “pre-multiplied” instead of “straight” on render settings.
The exact reason I still don’t know, I haven’t watched the video entirely yet, but changing this settings made the whole difference.

I have a bunch of layers and colors mixed, the option “on transparent” resulted in the most satisfying look.
I tried to create a black solid behind everything to avoid the transparency but the render remains the same.
I will not import in any editing program.
I guess my solution is to use the option “on black” and try to achieve the same result.

The funny thing is that for a client preview I recorded my screen playing the composition and then cropped. Lol.

When I render using “on black” it works, but I can’t manage to get the same results
