I wanted to make a short video of one image becoming another, in a sort of transformation. I thought that some kind of interpolation could help me so i downloaded ffmpeg. But I don't really now how to do it. I think I need to first make a video with only 2 frames and them use interpolation to do the magic, but I'm not really sure. Can anyone help me?
You may use this old, but very good program: Sqirlz Morph.
Its advantage is that it's a freeware, it has graphical interface, it's own help and tutorial, and it's easy to use.
