The Earth\ Spin\ 1-bit\ qtrle.mov file i have (2a73988ea94a1201a9cf477d71d3ff29) plays with 2 shades of blue in quicktime no white, identical to what the output with this patch looks like I will thus apply this patch unless there are some objections where can i find the file that plays with 3 colors ?
