Apple DVD Studio Pro 4 - Manual (Page 71)

• Motion Estimation: Choose a Motion Estimation setting that provides a balance between
quality and speed of encoding. This setting controls how much time is spent determining
the motion between video frames.
• Good: The fastest Motion Estimation setting. This mode does well even with significant
amounts of motion between frames, if the motion has minimal interfield motion
within frames. For example, footage that has been exposed to frame-rate conversion
or other effects processes tends to have little interfield motion. In general, use Good
with the One Pass encoding mode.
• Better: A good general purpose Motion Estimation setting. The Better mode provides
good results even with complex interlaced motion. Better works well for almost all
types of interlaced video sources, even shaky footage from hand-held consumer
camcorders. In general, use Better with One Pass VBR and Two Pass VBR.
• Best: This is the highest quality Motion Estimation setting and should be used for
the most demanding and complex motion for interlaced sources. It is slower than
the Better mode. In general, use the Best mode to maximize quality when using One
Pass VBR or Two Pass VBR.

• Method: Select when you want the asset to be encoded.
Note: An advantage of selecting “Background encoding” is that, once the assets are
encoded, the encoded versions of them appear in the Simulator and the Viewer when
playing a track. This makes it possible to see the video as it will appear on the DVD,
and not the QuickTime version. See
Is That the QuickTime or MPEG Encoded Version?
for more information.
• Background encoding: The encoding begins as soon as you import the asset. The
encoding takes place in the background, allowing you to continue working on your
project. A progress bar appears in the Status column of the Assets tab. Once the
encoding process finishes, the Status column displays Done. See
Default Columns
in the Assets Tab for more information.
• Encode on build: The encoding does not start until you complete your project and
build the VIDEO_TS or HVDVD_TS files.
Using the Integrated MPEG Encoder
Depending on the Method setting in Encoding Preferences, video assets can either begin
encoding as soon as you add them to your project, or they can wait until you perform a
build of the project.
