iMovie HD: About limiting clip length when importing
iMovie HD 6 allows you to limit the length of video clips when you are importing from a DV or HDV camera.
To configure these settings:
Open iMovie HD.
From the iMovie HD menu, choose Preferences.
Click the Import tab.
You can select the following settings:
Start a new clip at each scene break
Limit scene length
With the "Start a new clip at each scene break" option, iMovie HD automatically creates a new clip wherever there's a scene break (places where the camcorder was switched from pause to record during shooting).
With the "Limit scene length" option, iMovie HD automatically creates a new clip when importing reaches the time limit you've specified.
Notes
These settings are only effective when importing from DV and HDV sources. Capturing from an iSight camera does not allow you to limit scene length with these settings.
iMovie HD does not break up scenes shorter than 30 frames (about one second), so some short scenes may be merged with longer ones when imported.
If automatic scene detection is turned on and your imported footage isn't being broken at scene breaks, make sure the date and time on your camera are set correctly.
