Well, yes - but not in Proshow Gold. You need a video editor to be able to cut out pieces of the mp4 (unless you are talking about a case where someone in the video is holding a picture for example - you can still do that in a video editor but it involves a mask or overlay of a new picture for example). No simple way I can think of in Proshow Gold to edit an image out. In Producer, you could probably overlay the segment with a different image using keyframes)
You can't have too many gadgets or too much disk space !!
