hi.. how did you figure this out, and how did you change it? I bought fastcut online, received a product serial and registered with magix -- everything seems fine but when exporting movies it also adds the "made with fastcut" scene to the end.
I don't have Fastcut, but it would seem to me that the text in question is just that, text. Scroll to the end to where you see the Made with FastCut, select the T button at the right of the screen for the text editor, and you will probably see the text in the box. Simply change it or delete it. You may have to select the last scene first.
I have Fastcut. When you click "Finish Movie" the popup has a list to choose what quality you wish to make it in (720pi, 1080pi,etc...). At the bottom of that popup there is a checkbox that says "add fastcut closing credits", uncheck this box.
