How should I remove sketch from a board?

Hi,
I will remove a sketch from the board while someone drawing over it.

His hand is moving, camera is also moving, so obviously it will be hard
But I want to learn what is the most effective and easiest way to do it.

I think I gotta clone stamp every frame in the end

can we see the shot? basically it would require:

1. stabilizing the shot

2. clone (not frame by frame*) or other ways of removing the drawing (like an effect of some kind or exporting a frame to Ps, cleaning, then returning).

3.  re-introduce the motion back

4. rotoscoping the Arm

5. fix anything that need fixing (like lighting changes)

here's a thread demonstrating such technique:

Re: Problems with tracking

whatever technique you choose, it's not easy stuff and require a lot of practice and effort from a beginner.

*the reason frame by frame does not work for cleaning up a video is that you could never overcome the inconsistencies of the brush strokes in time. it will be very apparent that the pixels were altered. the only time frame by frame works is if the movement is abrupt or very fast.

Thanks a lot for your great response
Here is my footage:  Animated GIF - Find & Share on GIPHY

The scene will be cut to other shoot after drawing 1 line and will come back fastly while other line is drawing. After 4 cuts there will be no more need to hide the sketch because of actual drawing
So I just need to handle this about 7 seconds only while he is drawing actual lines

the method I described will be suitable for you. for rotoscoping, if the movement is this fast in real-time and not because of your GIF export, then this will be rather easy using Rotobrush. nevertheless, as I said, this is no beginner stuff and to pull this off successfully will require a lot of practice or a professional.
