I've done this with Ulead's editor and I haven't used Kdenlive much. What I would like to do is this:

I have two video clips A and B. I want video A full screen and video B in a frame or window in front of video A. I looked in the help and threads for moving frames, but didn't see anything. Is it possible to do this in Kdenlive?

Yes, just put both videos in the timeline, video b in track 1 and video a in track 2 (as long as b is higher than a). The apply the pan and zoom effect to clip b, so it is sized accordingly to where you want it in front of clip a.

Then, you just need a composite transition between the 2 clips

hope that helps
