314 Chapter 3 Basic Compositing
When selecting Optical flow, an analysis indicator appears to the left of the transport
controls underneath the Canvas to show that the clip is being analyzed.
If you play back the project before the analysis is complete, the clip will appear as if
Frame Blending is set to None. Once the analysis is complete, the indicator disappears,
and the clip will play back properly. If you wish, you may view more detailed
information about the clip analysis and stop the process before it is finished.
Important: When importing interlaced footage and using the Optical Flow method for
frame blending, if Field Dominance is not set to the correct value, artifacts may appear
in the retimed object.
To display more information about ongoing clip analysis, do one of the following:
m During active clip analysis, click the analysis indicator.
m Choose Window > Show Task List.
The Background Task List appears.
The Background Task List shows all processes Motion is working on in the background.
Each task is labeled, has a progress bar, and displays text describing how far along the
task is. You may cancel current and pending operations by pressing the stop button
next to the progress bar.
End Condition: A pop-up menu that lets you set how playback continues when the
end of the clip is reached. There are four options:
 None: The default setting. The object’s duration in your project is equal to the
duration of its source media file.
 Loop: When the last frame of the clip is reached, the clip loops back to the first
frame and plays again. This can cause a jump in the clip’s apparent playback unless
the clip was designed to be looped seamlessly.
