I liked the look of this. I must start using green screen again but Alpha over is just as quick unless I want the title to cast a shadow then green screen doesn't work.
Adrian: Unfortunately iMovie doesn't allow much in the way of manipulation with green screen objects. Pan and zoom are possible but I would have liked to dissolve or fade between the two sets of words. I think the only way would be to make the titles with the green background as a stand alone ordinary video so all available transitions can be used and then add that to the main video.
Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
