Limelite:
While in FCP with the timeline active, hit “M” twice. This brings up the “marker” dialogue box. You’ll see an option for “chapter markers” in that box. Whatever you name that marker will automatically be carried over to iDVD as a chapter heading. Then, when you’ve finished marking your sequence, export the quick time. Be sure to activate “export chapter markers” when doing this.
Note: Do the chapter markers in the FCP timeline as your last step of the process. These markers are only locked to the timecode of the sequence and do NOT update if you shorten the sequence. For example, if you put a chapter marker one minute into your sequence , then go back and trim out the first 15 seconds of your sequence, that chapter marker stays put and is now 15 LATER than where you put it. Other than this, the process works quite well. Dragging a sequence with chapters into iDVD will result in an automatic creation of “buttons” representing the chapters.
