Q: iMovie

Is your first clip a picture or a video? I thought I read you can only do it with a video.

Same issue. After putting all the video clips together and adding a theme, it locks up at about 95% of rendering the video when adding a theme. Hopefully they will fix his soon

Are you able to select a theme at all and it just not showing up? If so do you have a title style selected under clip settings? You need to have a title style selected in order for the theme to show up.

After adding theme, have you double tapped on clip and select Title Style to either opening, middle , or ending?

I too am unable to access my iPhone4's iMovie app's title style option. Does not function, and has yet to appear. What is shown as a demo on the apple site for the iMovie, and what was shown at the Keynote that introduced the app, does not, apparently yet show in real-life, and in person. Looking forward to them fixing it.
