VIDEO CONVERTER PRO FOR MAC
FLICKER REDUCTION: When
this switch is in the NORMAL
position, the Converter sends images
using fully interlaced Composite,
S-Video, and RGBS video signals.
However, thin horizontal lines in
the images might appear to “flicker”
on and off at a very fast rate. This
annoying flicker, if present, can be
virtually eliminated by setting this
switch to the FLICKER REDUCTION
position. There is a tradeoff with
this feature: you might notice a
slight loss of vertical resolution,
detail, or brightness.
FREEZE IMAGE: You might
want to freeze a frame of an image
sequence on the screen without
having to mess around with your
software. If this switch is moved to
the FREEZE IMAGE position, the
image on the Composite, S-Video,
and RGBS outputs is frozen. It will
remain frozen until you move the
switch back to the NORMAL
position, at which time whatever
image is currently being received
through VIDEO IN will be displayed.
4.3 Other Features
• If the computer input signal is
no longer present on VIDEO IN
because the computer has been
turned off or the input cable has
been disconnected, the image
will automatically “freeze” and
the LOCK indicator will go off.
• The VIDEO OUT output will
always display what is present on
the VIDEO IN input regardless
of the “display mode” the
computer may be in. If VIDEO
IN is at 1024 x 768 resolution,
VIDEO OUT will also be
1024 x 768. This is
not true
of the
Composite, S-Video, and RGBS
outputs: images in Macintosh
modes beyond 640 x 480 lines
will appear scrambled and out
of sync when translated into
these formats.
• The Converter supports both
the low-res 512 x 384 and hi-res
640 x 480 Mac modes. Some Mac
models will boot in one mode or
the other depending on the type
of monitor they are connected
to. The Converter makes use
of this capability: if a low-res
monitor is connected to its
VIDEO OUT output, it will
force the Macintosh to boot in
512 x 384 mode, but if a hi-res
monitor (or no monitor) is
connected, it will force 640 x 480.
