Re: Digital doodles
What lies beneath the moving pictures:
The masked area (in red) is the part of the picture that will remain static. The mask can be painted on as shown or a border drawn around it instead. I found painting an overall mask easier. The area with the arrows will move in the direction of the arrows. More or fewer arrows determine how the image moves.
the masked area on the right of the sky is necessary to stop the edge of the photo being dragged into the movement.
Going by experience, the mask has to overlap into moving area quite a bit to stop the part that should remain static from animating.
