SUMMARY
When you capture a video input signal using Creative Lab's Video
Blaster capture card with Video for Windows, the preview window in
VidCap may appear in black and white. This will be noticed whenever
the video format in VidCap is set to 8-bit palletized. This occurs
because the default palette used by the Video Blaster consists of
greyscale, black and white colors only. To capture in color when the
desired color depth is 8 bit, a previously created palette must be
applied, or a new palette must be captured from VidCap.
The following steps describe the method to apply a previously created
palette to the current capture file:
- From the File menu in VidCap, choose Load Palette.
- Select the .PAL palette file and choose the OK button.
The following steps describe how to create a palette from the incoming
video signal:
- From the Capture menu, choose Palette or click the Capture Palette
button on the toolbar.
- Select the number of colors to be used in the palette (must be less
than 256).
- Choose the Start button to create a palette from the incoming
video signal or click the Frame button to build a palette from the
currently displayed frame.
- Click the Close or the Stop button to build a palette from the
selected frame(s).
NOTE: A Windows palette may hold 256 colors; however, 20 of these
colors are normally reserved by the system, leaving 236 colors that may
be specified by the system. Palettes that do not redefine the 20
system colors will be processed more quickly within the Windows
environment. This "236" color palette is known as an "identity
palette" and may be created in PalEdit.
