Parameters in the Inspector
•
Time Remap: A pop-up menu that sets how time is remapped in the clip. There are two menu choices:
•
Constant Speed: Retimes the entire clip using the same value.
•
Variable Speed: Animates the speed of the clip over time.
•
Speed: A value slider that sets the speed of the clip as a percentage. The default is 100%. Values
lower than 100 play back the clip more slowly than its original speed and also extend the
duration of the clip. Values higher than 100 play back the clip faster than its original speed and
shorten the duration of the clip.
This parameter appears only when Time Remap is set to Constant Speed.
•
Retime Value: A value slider used to adjust the time value of the clip at a given frame. When
you set Time Remap to Variable Speed, two keyframes are generated at the rst and last frame
of the clip. The two default keyframes represent 100% constant speed. Adding keyframes to
this parameter and assigning them dierent Retime Values makes the speed of the clip ramp
from one speed to another.
This parameter appears only when Time Remap is set to Variable Speed.
•
In: A value slider that sets the In point of the layer, in both constant and variable speed modes.
Adjusting this parameter moves the layer In point to the specied frame without aecting the
duration of the layer.
•
Out: A value slider that sets the Out point of the layer, in both constant and variable speed
modes. Adjusting this parameter moves the layer Out point to the specied frame without
aecting the duration of the layer.
•
Duration: A value slider that sets the total duration of the layer. If Time Remap is set to
Constant Speed, adjusting Duration will also aect the Speed and the Out point. If Time
Remap is set to Variable Speed, adjusting Duration does not aect variable speed playback.
•
Reverse: A checkbox that controls whether the clip is played back in reverse.
•
Frame Blending: A pop-up menu that sets the method used to determine how the image
is blended during each frame of playback. The Frame Blending pop-up menu contains the
following items:
•
None: Displays the frame from the original clip nearest the source frame.
•
Blending: The default setting. Displays a blend of the individual pixels of adjacent frames.
•
Motion-Blur Blending: Applies a motion blur algorithm to the blended frames.
•
Optical Flow: Uses an optical ow algorithm to blend the two frames surrounding the
desired frame. Using this method aects playback performance most signicantly. To display
frames properly, Motion analyzes the clip to determine the directional movement of pixels.
Only the portion of the clip used in the project (the clip between the In and Out points)
is analyzed. When you choose Optical Flow, an analysis indicator appears in the lower-left
corner of the Canvas.
