>> properties" on the camera. The vertical viewing angle should be changed to
>> 0.75; leave the horizontal viewing angle at 0.67.
>> Next, create your Alice movie as usual.
>> At the very beginning of your movie, create a duration 0 visible change
>> (e.g. turn light brightness to 0 and then to 1). We will need this to
>> align the timing of the left and right clips. It serves the same purpose
>> as a clapperboard in a regular movie.
>> Move the camera 0.05 m left for the viewer's left eye.
>> Play the movie, then start the video capture (command-shift-5 on Mac).
>> Hit Restart on the Alice window. If you don't see the light black out, hit
>> restart again. Sometimes it's not visible, so you have to keep restarting
>> until you see the light blink.
>> Stop the recording at the end of the movie.
>> Move the camera 0.10 m right for the viewer's right eye.
>> Record the movie again. Make sure you see the light black out at the
>> beginning. When you save the recording, make sure you know which clip is
>> right and which one is left.
>> Trim each clip so it begins right after the light turns on. (You can use
>> QuickTime Player on Mac).
>> Create a new project in iMovie, and add both clips. Add the right clip
>> first so you know which is which. The one you add first is considered the
>> main clip. Add the left clip so it overlaps with the first clip.
>> Line up both clips on the left. Trim the longer clip to the length of the
>> shorter.
>> Select the upper clip and choose Split Screen.
>> Share the video to a file or whatever you want.
