Hello to all on the forum. Im quite new to the editing part, and am seeking advice on how to have a foreground motion image (eg head of a person) with a separate motion background image? The image does not have to be cropped around the foreground image, but i would like to find a programme that can vary the shape of the foreground image.

Also would like to know where i can gather some video effects/transition ideas from (eg internet sites) without sitting down and watching 1000 videos!!

Any help appreciated. Thanks in advance!
