Capturing a color palette when capturing analog video
The data type of a video sequence plays an important role in determining
the resulting size and display of your captured file. For example, 24-bit
True Color video contains the most colors and generally occupies the most
disk space (this is suitable for videos featuring a variety of colors such as
outdoor shots). To retain some color while at the same time saving disk
space, choose the 8-bit data type which, depending on your video capture
board, is either Grayscale or Indexed-256 Color. Indexed-256 Color data
types use a predefined color palette to show colors and are best suited for
low color videos, such as animations, and for video intended to be played
back in 256 color display modes. (True Color video will not display well in
256 color display mode as it often contains more colors than the monitor
is capable of showing.) In Video Capture, you can select which frames in
a video to create the color palette from.
To capture a color palette:
Click the Capture Palette button on the Standard toolbar or Palette:
1.
Capture Palette to open the Capture Palette dialog box.
Specify the number of frames from which you want to create the
2.
palette in the Continuous frames entry box.
If your video source contains simple images with few significant
changes, you only need to specify a low value, such as 5. If colors
change rapidly, specify a higher value. Generally, the more frames you
select, the greater the range of colors held in the palette. (You can
select from 1 to 100 frames.)
Select a capturing option from the Mode group box. If you want Video
3.
Capture to capture the frames for you, select the Auto option and enter
a value for the duration between captures. For example, if you specify
two seconds, a frame is captured every two seconds. (You can specify
an interval from 1 to 100 seconds.) If you want to capture specific
frames, select Manual.
