BG Clips

Conceptually, all movie clips at the timeline level are considered BG (background) clips. Because in Scene Composition (SC) mode, each of these clips is to serve as a "canvas" for composition of scene objects. Depending on their purposes and attributes, BG clips are organized into 3 groups: story (clips), Generic (clips), and User (clips).

story (clips)

This is the default tab space (of Asset Bin) appeared when you first enter Compose section. This tab contains thumbnails that represent movie clips re-purposed from the "Read" contents. They can be dragged to the timeline, or to the preview window for editing and preview. The 5 tags on the left denote housing spaces for story clips from Act 1 through Act 5. Clicking on each tag will bring you to the respective space for the designated Act. In current Comixware release, only clips of the first tag (temporarily assigned for Act 5) are available. The rest of tag spaces are reserved for clips from other acts that are to be upgraded in the future.

On some of 'story' thumbnails you see a tiny blue square in their upper left corner. This is to indicate that these are 'loopable' clips. A loopable clip means, whether it's of static or animated nature, that it can be repeated continuously as a "loop" without interruption in its movement (or non-movement). You can "loop" such a clip to desired length using "To Cycle" command from the Sene Length menu in SC mode. This is useful for prolonging dialog sequence, for cycling action or for overall timing adjustment.
