I followed the tips in this thread, today, and managed to make a time-lapse movie from over 3,000 photos at 0.1 second per frame. I'm using iMovie 10.0.9.
I think it went like this:
- Import the photos into iMovie as a new event.
- Your view should now be of the clips (photos) in that event.
- Ensure the View... Sort Clips By... shows Date so the clips are ordered in time sequence.
- Create a New Movie using the No Theme style, within that same event.
- In the Clips pane, Select All (cmd-A) to select all the clips.
- Add To Movie (press the "E" key).
Hopefully you will not see any transitions between clips! That happened to me on my first attempt, in which I dragged the clips into the timeline. Maybe my approach (press "E" to Add To Movie) avoided those automatic transitions. I can't find any magic setting or preference that controls the addition of automatic transitions, but maybe I stumbled across such a setting and don't remember it.
- Click one of the clips in the Timeline pane, then Select All (cmd-A) to select all the clips in the timeline.
- Choose Windows... Movie Properties (cmd-J) and click Settings in the Preview pane.
- In Photo Placement choose Fit.
If you don't see Photo Placement click on the crop icon (a rectangle with extended sides).
- Click the information icon (an "i" with a circle around it).
You should see a Duration box; erase what is in that box and type 0.1 (for a tenth of a second) or whatever duration you want each photo to consume in your video.
- Now you have the core of a time-lapse movie!
- Add titles if you want.
- If you want to add a transition, like a fade to black after the last clip, or a fade between clips, you'll need to select the neighboring clip(s) and extend their duration longer than 0.5 seconds (the default duration of a transition). After the transition is inserted you can fiddle the duration of the neighboring clip(s) to get the effect you want.

These photos were captured with a Nikon D300 camera on a tripod and set to Interval mode with a 20s interval. I used iMovie to present them at 0.1s each (200x real time), to add titles, and to add a pause and fade-to-black at the end of each day's photo sequence.
