and destination clips are matched during the period of transition producing
a seamless result. By default, Minimum Motion Loss is used to find likely start
frames in the source and destination clips when clips are appended to a script.
Optimized transitions can be computed by using Optimize Transition in the
upper right-hand corner of the Transition Editor dialog. Optimized transitions
use a minimum foot sliding method to compute transitions. Optimized
transitions take longer to compute, but produces very smooth motions.
Although only one arrow is used to represent a transition between two clips
in the Motion Flow Graph, any number of transitions can be named and
stored in the Transition Editor representing that transition. If, for example,
you create 5 different transitions between two clips for one script, all of these
transitions are available in a new script that uses the same two clips. Think of
Motion Flow Graph as a data storage area; if all of the scripts are deleted, the
transitions are preserved and can be stored in an MFE file.
Automatic Transitions
When you create a script, default transitions are used between the clips. Default
transitions use minimum motion loss and are quick to compute. However,
the best quality transitions are the optimized transitions. Once the Transition
Editor is open, the first thing to try, before manual editing, are the optimized
transitions (upper-right corner of the dialog).
Length (Transition Duration)
Set the duration of a transition in the Length field. A value of 10, for example,
creates a transition of 10 frames between the source and destination clips.
During the period of transition, the velocity of the source clip is interpolated
to the velocity of the destination clip. If the transition takes place at the last
frame of the source clip and the first frame of the destination clip, and Length
is set to 10, then the last frame of the source clip is interpolated with the first
10 frames of the destination clip.
Editing Transitions Manually (Ghosts)
Manually setting the Start Frame for the source and destination clips offers
the most control. Unwanted motion in either clip can be avoided and judging
the best Start Frames for both clips is left to you.
The Ghost area Frame spinners allow you to view and scrub the source and
destination clips by displaying stick figures (ghosts); yellow and red stick
figures represent the source and destination clips. When a suitable Start Frame
