Generic (clips)

There are 2 kinds of generic BG clips: static and animated. They are stored under bin tab in tag 1 and tag 2 respectively. (Note: Tag 3 and 4 are vacant in current release. These are spaces reserved for future assets implementation.)

Static BGs

Tag 1 contains 10 background clips that are made of static images. The default length of these clips is 60 frames which equals to 5 seconds long. But you can use Scene Length control to prolong or shorten these clips to any length you want in Scene Composition mode.

Animated BGs

Tag 2 contains 12 background clips that are made of animated images. Like static BGs, the default length of these clips is 60 frames. But you can use Scene Length control to prolong or shorten these clips to any length you want in Scene Composition mode.

Since they are animated backgrounds, other than the looks of the clips, their respective moving directions (left, right, toward or away from camera) also define these clips. These directional attributes are indicated on thumbnails by a red square symbol that has a white arrow in it. Depending on which way it's pointing, the arrow denotes the moving direction of that particular background:

Left pointing arrow = panning to the right.
Right pointing arrow = panning to the left.
Up pointing arrow = moving toward camera.
Down pointing arrow = moving away from camera.
