OutputRes
Two fields where you enter the horizontal and vertical output resolution you want to
convert the media to, to scale it up or down. Scaling an image sequence using the
OutputRes parameter of the Convert options results in higher-quality output than
using Shake’s Transform nodes.
Recursive
Turning this parameter on enables a different resizing method, which can be sharper
when enlarging some kinds of images. Try it on one or more representative frames to
see if it helps.
Note: The recursive setting may also enhance unwanted noise, depending on the image.
AntiAlias
Turning this parameter on improves the quality of conversions when you’re scaling
media up. For example, when converting standard definition video to high definition,
turning on AntiAlias smooths out jagged edges that might appear in the image.
Details
A built-in sharpening control that lets you add detail back to an image being enlarged.
Unlike other sharpening operations, the details setting is able to distinguish between
noise and feature details, and generally doesn’t increase unwanted grain. Increasing
this parameter may introduce jagged edges, however, which can be eliminated by
turning on the AntiAlias parameter.
Motion
Two options determine the trade-off between image quality and processing time. Fast
makes motion interpolations using a mesh warp, and is generally the only setting
necessary for purposes of remastering.
Note: Best, the most processor-intensive mode, uses motion vectors to track each pixel
from frame to frame to interpolate new frames, and should only be necessary when
doing retiming. For more information on the parameters available for the Best setting,
see page 37.
DeInterlacing
Similarly to the Motion parameter, two options let you determine the trade-off
between image quality and processing time—Fast and Good. These settings represent
two levels of mesh warping used to interpolate data from both fields of each frame.
