Glad to hear you resolved your issue and thanks for the update Maz.
SMIL region is in built, it using for smooth transition settings . It would not create any issue in your output or rendering.
Thanks for your input.....BUT....... I still cannot render in PREL7 a slide show created & imported from pse7 and edit in PREL7 using the 'breakapart' facillity. It will render but will not stay rendered when saved. The only way to stay rendered is to delete the 'region' video bit and introduce a tracke matte colour.
I await your advice on how to stay rendered after saving the project.
Cathrine, Have you seen my reply to your post? I am keen to know if it's me or the program?
