A blend table entry that sets the cross-fade time between two clips.
The cross-fade is linear, with no easing. The weight of the old clip goes from 1 to
0 and the weight of the new clip from 0 to 1. Positions and scales are
interpolated linearly, and rotations take the shortest path.
F32 = 0.20000000298023224 The cross-fade time, in seconds. The fade runs on the clock of the new clip: the elapsed time is multiplied by the playback speed of that clip, so a clip that plays at double speed fades in over half the time.
0 or less is an immediate cut.
