I have a video in which I would like to paste a photo, but without loosing the audio. So for example from second 23 to second 27 the video is replaced by my photo, but the original audio is still played. How should I do this?

Currently you can overlay a video on top of another, in a static position. I suppose overlay could be extended by making x/y depending on time, but currently not yet possible. Patches/feature requests are welcome.
