I used to make videos of my work using some free video making site such as "One Media". I know that Microsoft has a movie maker comes with windows operating system. Finally I got some time to try the Windows Live Movie Maker.
It is a breeze to make the movie from my pictures using the software. Here is the Bird, Nature and Love paintings collection. With the Windows Live Movie Maker, my video will have no advertisement from third party now.
The only difficulty is to find a suitable nice music to go with the movie. In this case, I download Beethoven's Moonlight Sonata. If you use some modern music, it may have complications of copyright problem.
