thank you dave
i was ok with the RGB separation.
but i don’t think it is only a question of opacity.
there is something like a wiper with a very high feather.but i am not sure

i haven’t AE now so i can’t test
but it is something like that, maybe

Thank you for your answer.
I knew about this drost effect, but, as in my case the images don’t need to “blend”, i wonder if I could find a simply way to achieve the effect, maybe with an expression ?

[Emmanuel Gobert]

Very interesting, thank you Andy

[Emmanuel Gobert]

ok thank you for answering

[Emmanuel Gobert]

No answers, really ?

[Emmanuel Gobert]

No answers ?
Maybe a stupid question ?

This is for a monthly TV show, where the actor is shot in front of a white screen. Nothing else.
My work is, after editing, to put some graphic elements and some FX to enhance the scene.
So, to answer your question, because of a very limited budget, no special preparation for this shot.
So I am not preparing for the shoot (this is already shot), and I am not trying to “rescue” anything.

hi, maybe you can post a result ?

Hi everyone,
I’ve found this great expression which is solving my problem :

n = 0;
if (numKeys > 0){
n = nearestKey(time).index;
if (key(n).time > time){
n–;
}
}
if (n == 0){
t = 0;
}else{
t = time – key(n).time;
}

if (n > 0){
v = velocityAtTime(key(n).time – thisComp.frameDuration/10);
amp = 0.05;
freq = 3.0;
decay = 6;
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{
value;
}

I copy this in the rotation parameter, and on each keyframes that end a movement, it adds a little bounce effect.
found on gray machine.

Thanks,
I know about pen tool, because I know photoshop very well
So thanks for the links, I’ll try all that things
