I'm very new to After Effects. I wanted to create an effect and I did succeed in doing it but now I forgot how I did it and for the life of me I cannot figure it out anymore.
Basically I have 02 pictures - exactly the same but one is a black and white copy of the other. I want to somehow use layers to keep the coloured picture under the b&w one just erase the b&w picture on top to reveal the coloured picture underneath. The I want to use the brush stroke effect to make an animation to look like the piture is being coloured.
I even exported a video of when I did it. Heres the YouTube link so that you can understand what I want:
Its very simple I'm sure but please someone help me! I really need it and I'm desperate. Bear in mind that I'm a beginner so please explain accordingly :)
