I use several dvd authoring apps. as well as VEM, on a regular basis. I try to use new and varied techniques, and to try to get to know as many features as possible, and so far I am quite satisfied and proud of my productions.
One thing I frequently need to do, is to take a map, and add a moving line or row of dots to show a route or progress during a documentary. The only way I have found to do this EASILY is to create several still images each one with a different line incorporated in it, and then merge them during the show to give the (crude) impression of gradual movement.
Is there a way to "draw a moving line" and superimpose it on a video footage? This is obviously a different requirement to using a normal green screen, or adding text, although if the adding text was adjustable over the full two dimensions of the frame that might be a thought?-Interested to hear how others get round this annoyance?
