how to apply LUT to Live capture?

Hi,

I try to apply LUT using image/Lookup Tables/... on Live capture 
(File/Import/Video) but ImageJ doesn't allow me to do that. It pop up the 
window saying "Color tables cannot be assigned to RGB Images." So I try to 
change capture window to 8-bit using Image/Type/8-bit but the Exception window 
pop up and list class names as below:

java.lang.ClassCastException: [B
 at QuickTime_Capture.displayFrame(QuickTime_Capture.java:131)
 at QuickTime_Capture.preview(QuickTime_Capture.java:124)
 at QuickTime_Capture.run(QuickTime_Capture.java:66)

Does anyone know how to solve the problem?
