I may have missed the discussion about this but when animating HRV, as the terminator moves across and the pictures descends into darkness the resolution goes to 'pot', square edged chunks of dark grey and black. I can see this effect on some of the LRIT images as well. Is this an effect of the lossy compression or the fact that graphics cards only use 8 bits even for a greyscale.

regards, Guy
