Hi

Yes you can apply effects and manipulations to video in GEM.  The 
pix_ objects exist for this purpose.  Pix_offset will change color 
values by adding or subtracting a static value from the image. 
Pix_invert inverts the images color values.  You can also convert the 
RGB image to grayscale.  There are lots of other objects available 
for doing everything from blur to mixing to chroma-keying.  Various 
non-pix_ objects also manipulate the image in unique ways using 
openGL.
