We've picked up a Lowell catalog at NAB and after going through the lineup, we've got our wish-list items circled. (The same units my son was leaning towards before NAB.)

Well, I meant the color temperature of the background video you're keying in, rather than the color temp of the green screen. You had, for example, some daylight (very blue) as background, while your car was lit very orange. If it doesn't look like your background and foreground are lit by the same source (the sun, in this case), it's much easier to spot the key.

Agreed. We applied some correction, but our lighting options were limited.

Just because it has 4:2:2 in front of it means almost nothing by comparison to what it once meant.
