This parameter appears only when Time Remap is set to Constant Speed.
Retime Value: Displays the time value of the clip at a given frame. When you set Time
Remap to Variable Speed, two keyframes are generated at the first and last frame of the
clip. The two default keyframes represent 100% constant speed. Adding keyframes to
this parameter and assigning them different 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: Sets the In point of the layer, in both constant and variable speed modes. Adjusting
this parameter moves the layer In point to the specified frame without affecting the
duration of the layer.
Out: Sets the Out point of the layer, in both constant and variable speed modes. Adjusting
this parameter moves the layer Out point to the specified frame without affecting the
duration of the layer.
Duration: Sets the total duration of the layer. If Time Remap is set to Constant Speed,
adjusting Duration will also affect the Speed and the Out point. If Time Remap is set to
Variable Speed, adjusting Duration does not affect variable speed playback.
Reverse: This checkbox controls whether the clip is played back in reverse.
Frame Blending: 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 flow algorithm to blend the two frames surrounding the
desired frame. Using this method affects playback performance most significantly. 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.
