Apple Motion 4 - Manual (Page 60)

When Motion Blur is enabled in the View pull-down menu (View > Render Options >
Motion Blur) and you are using the default export preset (“Movie - current project and
canvas settings”), your project is exported with motion blur. (The default codec used
is Apple ProRes 4444.) When this default setting is used, any options chosen in the
View pop-up menu (or the View pull-down menu), as well as settings in the Project
Properties dialog, are exported.
However, if you choose any another preset, motion blur is disabled and must be
manually enabled. For example, if you choose DV NTSC Movie, motion blur is disabled.
You can override a preset’s settings, as described below.
Note: When opening a Motion project in another application such as Final Cut Pro,
Motion Blur in the View pop-up menu controls whether or not motion blur is applied.
For information on overriding current project settings for motion blur on export, see
Overriding Project Settings Selected in the Render Pop-Up Menu .
• Field Rendering: Turning this setting off disables field rendering, which is required for
smooth motion playback on a TV monitor. Field rendering nearly doubles rendering
time, so disabling this item will typically result in a significant performance improvement.
When Field Rendering is enabled in the View menu and you are using the default export
preset (“Movie - current project and canvas settings”), your project is exported with
field rendering. (The default codec used is Apple ProRes 4444.) When this default setting
is used, any options chosen in the View pop-up menu (or the View pull-down menu),
as well as settings in the Project Properties dialog, are exported.
However, if you choose another preset, field rendering is enabled based on the selected
preset itself (whether that particular codec requires fields). For example, if you choose
DV NTSC Movie, field rendering is enabled because fields are expected. If you choose
DVCPRO HD 720p24 Movie, field rendering is disabled because it is a progressive-scan
(no fields) movie format.
Note: When opening a Motion project in another application such as Final Cut Pro or
DVD Studio Pro, the Field Rendering setting in the View pop-up menu does not control
whether field rendering is applied or not. This is controlled in the Project Properties
dialog (press Command-J). When Field Order is set to anything other than None, field
rendering is used in the other application, regardless of the Field Rendering status in
the View pop-up menu.
For information on overriding current project settings for field rendering on export,
see
Overriding Project Settings Selected in the Render Pop-Up Menu .
• Frame Blending: Turning this setting off disables frame blending in the Canvas. Frame
blending can smooth the appearance of video frames by interpolating the pixels
between two adjacent frames to create a smoother transition.
