Rendering and Rerendering Existing Traditional Motion Effects
In certain situations, you might need to render or rerender existing traditional motion effects. To do this, follow one of the procedures described in Rendering Effects.
Information about the type and render status of motion effects appears in the Timeline in the same form as that used for other effects. Each motion effect type has a distinct effect icon, as shown in the following illustration.
Duplicated Field Motion Effect icon
Both Fields Motion Effect icon
Interpolated Field Motion Effect icon
VTR-Style Motion Effect icon
Color-coded dots appear on Motion Effect icons to indicate whether they require rendering.
Use ExpertRender to identify motion effects that require rendering.
When you render motion effects, the Avid editing application checks the Motion Effects Render Using option in the active Render setting. If the Motion Effects Render Using option is set to Original Preference (the default setting), the application makes no change to the type of motion effects when it renders them. If the Motion Effects Render Using option is set to a specific motion effect type, the application changes all motion effects to that type when it renders them.
Whenever the Avid editing application changes the motion effect type during a rendering operation, a message appears in the Console window, providing information about the change. For more information, see Creating and Using Render Settings and Displaying Information About Motion Effect Type Changes.
The following is a list of the circumstances in which you might need to render or rerender motion effects.
  You need to render any motion effect that requires rendering for successful playback if you did not render that effect at the time you created it. This kind of effect appears with a blue dot in the Timeline until it is rendered.
  You might need to render a motion effect so that it will play successfully in a complex sequence even if that effect would not normally require rendering. (Motion effects that display a green dot in the Timeline might not play back in real time under some circumstances.) For more information on overall real-time playback capabilities, see Understanding Effect Playback Capabilities.
  You might need to render or rerender motion effects when you edit them into a sequence and perform trims or apply transition effects. If an effect that was previously rendered (no colored dot in the Timeline) or that previously played in real time (green dot in the Timeline) changes in such a way that it requires rendering, it will appear with a blue dot in the Timeline. Only those parts of the Motion Effect clip that have been changed by your editing require rendering. Using the Render Ranges command in the Timeline Fast menu, you can see which parts of the motion effect require rendering. For more information, see Customizing Render Ranges Display.
