Rendering Considerations When Creating Traditional Motion Effects
When you first create a traditional motion effect that requires rendering, you can render immediately or create an unrendered version that you can render later in your workflow.
The Avid editing application creates traditional motion effects using one of four different types — Duplicated Field, Both Fields, Interpolated Field, and VTR-Style. The Duplicated Field and Both Fields types enable some motion effects to play in real time; the Interpolated Field and VTR-Style types always require rendering.You select motion effect types based on the quality you need for the final motion effect, the rendering time that each type requires, and the media with which you are working (some types are useful only when you are working with two-field media).
  For more information on motion effect types, including their relative quality and their compatibility with different types of media, see Traditional Motion Effect Parameters.
Your Avid editing application allows you to preview some kinds of unrendered traditional motion effects in real time even if they require rendering for final playback. The application cannot preview other kinds of unrendered motion effects; these effects will play as filler until they are rendered. The following table provides a summary of playback capabilities for traditional motion effects.
