Usage guide for Compositing with Carbon or MuxMan
Motion Concepts

Every element can have any of its parameters change through time, and appear at any time. To do this each element has a display time and a duration. The display time is relative to the start of the composite. This allows each element to appear later in the composite (and also allows the compositor to become a non-linear editor). Within that period of time "onscreen" each element has a list of transitions which themselves have display times and durations. Transition display time is relative to element display time, so moving the element in time does not alter the effects.

To create a motion composite first go to the timing controls and set a framerate and duration for the entire composite. Don't worry, it can be changed later.

Elements can either have a specific duration, or indefinite. Leave the duration at zero for the element to remain on screen for the rest of the composite. To create a motion element click on "create" in the "current transition" box. The transition will be set to all the available time on either side of the current time. Change this if you want it shorter with the TimeCode controls or the "set start" and "set end" (these set the respective end to the current position).

Now set the view time to one frame after the transition and, using the mouse or switching back to the position controls, alter the element to the way it should appear at the conclusion of the transition. Transparency and rotation can be altered using the blend controls, and colors altered using the color proc controls. You may also go back to the start and change that appearance as well.

Note: position, blend rotation, blend opacity, and color proc controls are active only during the frames leading up to the first transition for setting the base values, and after each transition (until the next transition) to set end values. At all other frames the controls will grey out.

There are functions in the right-click menu to "unbend" (restore aspect ratio), flip vertically and horizontally, and to "invert size" which causes the image to flip on both axes, effectively rotating it by 180 degrees. The size control can also go negative, and flips can be done with the mouse by dragging one edge over the opposite edge.

Source AVI playback framerate can be adjusted to synchronize or add effects such as slow-mo. Setting the framerate negative causes reverse playback from the start point, so make sure it is advanced. In other words if you wish to play 00:00:05.000 to 00:00:15.000 in reverse set the start time to 00:00:15.000 AVI times are calculated using the framerate in the file, so altering playback speed does not change the start time value.
