User Guide
Use the scrolling bar to select a custom setting for Speed v. Quality.
This will affect how fast or slow the encoding is processed based
on the quality of the output you need. Rate Control and Bitrate
selections will also affect the quality of the video as well as the file
output size. Higher bitrates lead to better quality but larger files.
We’ll also cover some of the Rate Control options under “Your First
Multipass” section.
Codec
- Speed/Compression performance, Frame Control,
Motion Estimation
Under the Codec tab, you can select the Codec Performance. The
default encoding mode is “Balanced,” which finds a happy medium
between the degree to which the file is compressed and the speed
at which it is encoded. You also have the following options to choose
from, depending on the result you are looking for from your file:
•
Fastest:
conversion will finish quickly; designed for high
resolution live capture or slower computers. This could result
in some quality loss. Higher bitrates can compensate for some
of the quality loss.
•
High Performance:
a faster conversion but slightly lower quality
than Balanced with moderate compression. Higher bitrates can
compensate for some of the quality loss.
•
Better Quality:
conversion will take slightly more time but
compression is efficient and quality is retained.
•
Extreme Quality:
creates highly compressed files with production
quality video, but conversion is much slower.
•
Insane Quality:
when quality is your sole concern, regardless of
the time it takes to complete.
Other options in this tab include Frame Control and Motion
Estimation. For more information on how these affect your video
output, take a look at the DivX Codec User Guide (opens an .exe file).
Video
- Custom Resolution, Aspect Ratio, and Image Processing
The Video tab lets you set custom aspect ratios or resolutions if you
do not want to use the defaults defined by the DivX profiles.
Under Video Resolution, you can select from standard Aspect Ratios
(Square Pixels, PAL 4:3, NTSC 4:3, PAL 16:9, NTSC 16:9) or set a
custom PAR for both the input and the output. Or, use the “Custom
resize” option to set a custom resolution.
Advanced Settings
You’ll notice that on the bottom of every tab is also a button called
“Advanced.” This button opens an advanced Settings window where
you can enter manual CLI codec settings, change your Temporary
Files Folder, as well as some other settings such as disabling the
feedback window.
