Timewarps Render
Using
Determines the processing method when your Avid editing application render or rerenders
Timewarp effects.
The Original Preference, Duplicated Field, Both Fields, Interpolated Field, and VTR-Style
options are the same as those for Motion Effects Render Using (see the preceding
descriptions).
The Blended Interpolated and Blended VTR options are also available. These options add
pixel blending to the Interpolated Field or VTR-Style techniques. Your Avid editing
application blends, or averages, pixels from the original frames or fields to create
intermediate frames or fields. For example, at 25% speed, your Avid editing application
creates three blended images between outgoing Image A and incoming Image B. The first
blended image weights the pixels from Image A at 75% and Image B at 25%, the second
weights the pixels from Image A at 50% and Image B at 50%, and the third weights the
pixels from Image A at 25% and Image B at 75%. Objects in motion from Image A to
Image B appear to fade out of Image A and fade in to Image B.
Timewarp effects that render using Blended Interpolated or Blended VTR render less
quickly than Interpolated Field or VTR-Style.
Motion Effects
Render Using
Determines the processing method when your Avid editing application renders existing
motion effects. The following options are available:
• Original Preference: Effects render as whatever type they were when originally created.
• Duplicated Field: Displays a single field in the effect. For two-field media, this drops
one field of the image, resulting in a lower quality image. For single-field media, this is
usually the best choice because of its speed (the other options do not improve effect
quality for single-field media).
With JFIF resolutions, this option causes the effect to render in the shortest amount of
time. With DV and MPEG resolutions, the effect renders approximately as quickly as it
would if you select Both Fields as the rendering option.
You can use this option to remove unwanted field motion in interlaced material brought
into a progressive project.
• Both Fields: Displays both fields in the effect. For example, the first two frames of a
half-speed (50%) slow-motion effect repeat the original Frame 1 (both fields) twice.
This option is good for shots without inter-field motion, NTSC or PAL film-to-tape
transfers, and still shots. With footage that includes inter-field motion, this option
might result in minor shifting or bumping of the image because it disturbs the original
order of fields: a Field 1 appears both before and after the corresponding Field 2.
The effect renders relatively quickly. For best results with this option, use evenly
divisible frame rates.
