FCPX is different. I had quite a time to figure out how to create a DVD with chapter markers from FCPX.
Here is how to do it:
- Hit M twice. This will create a marker and open it for editing
- Use the third icon from the left – this shows up as ‘Chapter’. You can either leave it as chapter numbers or give unique, descriptive titles for each chapter.
- Use the movable marker to choose the desired placeholder image on the chapter menu.
- Export using the ‘share’ button and voila, you have the chapters all neatly lined up
This video explains it very well.
