254 Pinnacle Studio 9
Using codecs that have not been certified by Pinnacle
Systems for use with Studio preview-quality capture
may produce undesirable results. Pinnacle Systems
cannot provide technical support for problems
associated with the use of codecs that are not so
certified.
Options: This button gives you access to any setup
options offered by the codec (compression/decom-
pression software) you have chosen.
Compression: Use this dropdown list to select the
codec you want to use.
Width, Height: These fields control the dimensions of
the captured video.
Frame rate: The number of frames per second you
wish to capture. The two numerical options represent
full-speed and half-speed video respectively. The lower
number (14.985 for NTSC, 12.50 for PAL or SECAM)
saves disk space at the expense of smoothness.
Quality, Data rate: Some codecs present quality
options in terms of a compression percentage (Quality),
and others in terms of the required data transfer rate in
KB/sec (Data rate).
MPEG type: Select one of the two flavors of MPEG
encoding: MPEG1 or MPEG2. The former is almost
universally supported on Windows computers; the
latter gives better quality for a given compression ratio.
Resolution: This is a dropdown list giving the
resolutions available with the capture options you have
picked. Increasing both the width (the first figure) and
the height by a factor of two increases the amount of
data to be processed by a factor of four.
