Problem with a job. Draw My Life.
on Mar 6, 2019 at 2:21:56 pm

Hello guys!
First, I apologize for the writing, I'm using google translator.
Second, I'm new here so if I'm posting in the wrong place I'm sorry.

I'm doing a work in draw my life. To improve the work I would like to do some animations in motion graphics, for after effects.
But I have a problem, my clients are a bit complicated, sometimes they ask for the change of a drawing on paper. I guess from the after effects I can crop the old drawing and put a new design suggested in the change.
But I have to make a frame-by-frame cut-out whenever the designer's hand goes over the new drawing.
This clipping takes a lot of time to do since it is frame by frame.
So I would like to know if anyone knows a technique to facilitate this, or something that I can change in production, like a different lighting or a different camera position.

I use a Gh4 filming in 4K and an ARRI lighting kit with a lighting balloon

Thank you for your help....

PT-BR: (I hope that's what you speak).
Na maioria das produções mais baixas, a mão que desenha é filmada em chromakey, a gente só simula a posição da ponta da caneta conforme revela o desenho. Pela sua descrição você está realmente desenhando algo ou filmando sobre o branco, é isso? Se for o caso, dependendo da iluminação, da pra fazer um key pela cor da pele da mão pra evitar rotoscopia.

On most low cost productions, we shoot the hand in green screen, we just simulate the drawing while positioning the pen's tip as its being revealed . From you description I see you're either actually drawing or you're just shooting the gestures on white. Is that it? If that's the case, depending on the lightning, you could generate a key for the hand and avoid rotoscoping.
