I'm not sure if those color adjustments really help. Desaturating color helps make bad cinematography less obvious but it doesn't really go at the problem. It's easy to see the color doesn't look as good as a usual film but does anybody know exactly why? What attributes is it missing? The other thing is temporarily increasing the saturation might help reveal the problems better.
I don't want to brag or anything but I think I have a pretty good eye for color correction. (I should thank this site as well as Lucas screwing up the 2004 dvds so badly for helping me develop it.) I enhance and crop most of the photos I upload to facebook while many others don't even bother to rotate the pictures (which FB lets you do easily) that are vertically oriented. I'm pretty good at removing a color tint and I just discovered on Vegas that I can adjust the midtones/highlights/blacks of color separately. From what I've observed the color space needs to be stretched out; that is colors look more vivid with more contrast if the bright areas don't have the same tint as the dark areas. This ability seems to be something 1 ccd cameras lack. I was able to use this 3 way color correction technique to great success for a music video I did of my sister. I used my TRV-615 Hi8 but I think the correction (along with more saturation) made a lot of the clips look like they were shot with a 3ccd camera.
Does it make sense that the attributes of the HD video to film could be similar (although not nearly as drastic) to differences between a 1ccd and 3ccd camera?
