About setting the display format
For best results you would usually set the display format color
depth to match the video source color depth. If the display format
and video source color depth do not match, the device driver or
video capture application converts the color resolution of images
as they are captured. This conversion can put extra demands on
the video capture workstation CPU.
Note: For a definition of color depth, see
“Color depth, bits per
pixel (bpp)” on page 45 .
In some cases; however, you may want to set the display format
to a different color depth than the video source. There are a
number of possible reasons for doing this. For example:
• You are recording captured images to video and your video
codec is not compatible with the color depth of the video
source. In this case you could set the display format to match
the requirements of your video codec.
• You want to save disk space. Setting display format to a lower
color depth reduces the size of recorded image files or videos.
Using a lower display format color depth means that the video
and image files saved by the video capture application are
smaller and use less disk space.
