You want to inlay the characters in a set you already previously filmed → film 2 (let’s imagine this scenario).
Transfer your two videos on your pc. Now open EKD, go in the menu Video > Converting images into a video (… and transform your two films into images [if your films are .avi DV, or mpeg2, mpeg1, EKD will do it without any problem]).

Once you do thist, you have to make the compositing between your background images (images in the film 1) and the images of your characters (images in the film 2) … in EKD … Image > Various > Image Composite. To end the process, you have to transform the mixed images into a video file, and (in EKD) … by the menu Video > Converting images into a video.
