Connecting video equipment
You can connect video equipment to your Power Macintosh so that you can
work with video images on the computer. With your Power Macintosh, you
can view video on your monitor, capture single video images, and save
digitized video in files.
Your Power Macintosh can display and use video images from a variety of
sources. To view video on your monitor, you connect video equipment to the
video input port on the computer.
Your Macintosh can work with two video formats:
m S-video
m composite video
S-video is a high-quality video format used by many video cameras and
VCRs. Most televisions, most VCRs, and laserdisc players use the composite
format. To find out which format your equipment uses, check the manual that
came with your equipment.
