just read.. I cannot figure this out!
I have footage of someone walking past a wall with graffiti along it, I used a tripod so the footage is stable and I have made a freeze-frame of the wall without the subject in it and taken out the graffiti and replaced it with brick wall using stamp tool.
Is there a way to have the subject walk past the wall with no graffiti and then have it slowly be painted in as he’s walking past. I’m sure theres a way but cant figure out how to change the background whilst someone is walking past.
please help! this is for my degree.
Thank You. x

If I understand you correctly, what you’d want to do is put the clip with the graffiti underneath the clip where you’ve removed it, then use a mask on the upper layer which animates over time to make the upper layer disappear. The property to key frame is Mask Shape. I’d also suggest that you draw the mask in the first frame of the clip using the pen tool and create a number of points so that you can adjust the mask tightly to the figure as it moves along. If you are not as interested in making the reveal look like the figure is the cause of it, you might be able to get away with a standard square mask and a bit of feathering. -R

It sounds like you have all the pieces you need.
The still with the wall with graffiti and no person in it is a “clean plate”. You can use Difference Matte to create a alpha channel for the person walking by- that is to remove the wall and just have the person on a layer. This way you can put the clean wall behind and reveal the graffiti on it using animated masks.
