Notice that you can “see into” the video by looking at the images stretched across time,
just like looking at filmstrips unrolled on a table. Each “filmstrip” represents a video clip,
or a segment of video that begins at the moment the camera started recording and
ends when it stopped recording. Typically, each Event includes several video clips, one
for each time you started and stopped the camera while recording the Event.
By default, iMovie displays one image for every five seconds of video in a clip; you can
change this setting to “unroll” (expand) the filmstrips further, or “roll them up” (contract
them), depending on how you like to work. The duration of each clip is visible on its
left end as you move the pointer over it.
To expand or contract the filmstrips:
 Drag the clip thumbnail slider to the right to reduce the number of images displayed
for each clip, making each filmstrip shorter.
 Drag the clip thumbnail slider to the left to increase the number of images displayed
for each clip, making each filmstrip longer.
Expanding and contracting the filmstrips using this slider does not alter your video in
any way; it only affects the view you have while you’re working.
