Contents 45 Troubleshooting
Problem Live video is displayed in color, but captured clip/still is in black
and white.
Condition The Video format is set to 8-bit Palettized and a palette has not
been set for the clip/still. The Windows grayscale palette is used
by default.
Solution Set a palette for your clip/still. See the documentation supplied
with your capture application for details on how to set a palette.
Problem A large number of frames are dropped when capturing video
clips.
Condition The data rate required to capture the video clip is too high for
your system.
Solution Optimize your computer for streamed video capture as follows:
i. defragment your hard disk.
ii. make sure that the capture file, if required, is large enough for
the clip you are capturing.
iii. remove any disk caching programs, such as SmartDrive, if
you are capturing to hard disk.
iv. remove any disk-doubling software, such as Stacker and
DoubleSpace, if capturing to hard disk.
v. maximize the amount of conventional DOS memory by
removing any unused TSR programs or device drivers from
your AUTOEXEC.BAT or CONFIG.SYS files.
vi. capture the clip to memory if it is short enough.
If the number of frames dropped is still unacceptably high,
reduce the data rate of the clip by changing the image quality.
Try one or more of the following:
i. reduce the size of the image you want to capture; for example
capture the image at 160 x 120 instead of 320 x 240.
ii. reduce the audio quality if you are capturing audio. You can
reduce the sample rate (usually 44, 22, or 11 kHz), number of
channels (stereo or mono), or bits per sample (usually 16-bit
or 8-bit).
iii. reduce the number of colors in the image; for example
capture the image in 65 thousand colors instead of 16 million.
