For any who have not seen this unit, it'a awesome.
The screen caps are not great to begin with, but you can see on the left how much more accurate the colors are. You can adjust brightness, contrast, color saturation and hue with this unit. "So whats the big deal, I can do all that in my NLE" you say? True you can, but in doing so you increase the rendering time significantly. If you're in a time constrained situation, this is a God-send. I've found that almost every home video can use some amount of correction. They also have a unit that does sharpness and detail, but I dont find it near as noticeable.
