I’ve been using Adobe Premiere Pro CS3 recently to put some videos together and thought it was about time to start authoring DVDs with chapters. It seems you can’t import Premiere projects into iDVD with chapter markers and nor can you set specific chapter markers in iDVD (just equally timed markers).
Instead I tried importing the Permiere project into Encore which DOES accept chapter markers but Encore appears to be the single most bug ridden Mac application ever. And multiple Google searches seemed to support this theory.
So ultimately I made the inefficient but effective decision of exporting the Premiere project, importing it into iMovie (thereby doubling the amount of storage space needed), adding chapter markers and then sharing with iDVD.
