My iMovie09 seems to be dropping number of available color when I import anything. This effect is noticeable in particular in black and white movies. Anytime people are in a room or whatever and, for example, walk by some shadows, there is extreme pixelation of all the low-lights and they jump all around hopping from one shade of gray to another (extremely distracting). An entire wall of a room can look like jaggies moving all around. One thing is that, even though I'm importing and then export with the full original size options selected, the movie seems to come out in 960 size anyway. But that may be separate issue. The main thing is that the movie seems like it looses its number of colors during import. Anyone have any ideas what's going on with this? Is iMovie just not for HD movies. This is driving me nuts.
