Is it possible that what you are seeing is the inter-frame motion of the 59.94p frames? In other words, let’s say your camera actually records 59.94p and FCP has to remove duplicate frames during capture. But duplicate frames are not removed for some reason–option not checked for instance. In the downconvert, both of the 59.94p frames are displayed within the 29.97p frame. So, whenever there is motion, there is a stair-step caused by the display of both 59.94p frames as one 29.97p frame. I don’t know if this happens or is possible, but it’s a theory. On still subjects you wont see it because both 59.94p frames will look essentially the same–no inter-frame motion.
I do wish someone could explain this. I’ve had a similar issue with 59.94p shot with a Panasonic HVX-200 and encoded to MPEG-2 for SD DVD. On moving subjects, there is an ugly, big stair-step or jaggie. I haven’t found the way to get rid of it completely. Using the Panasonic frame rate converter doesn’t work because the speed gets cut in half–unless I’m missing a setting in the FRC.
Anyhow, I don’t want to hijack this post to another subject, but to propose the above theory.

Chroma won’t work with this method either. You’ve subtracted the other colors out of the white, so you get no comparison of blue and white bars.

Adjusting hue is a process of comparing the various colors to each other so that they are in the correct balance, right? So, if your source image only has one color, how can you compare anything?
When you use the blue-only switch you are seeing all the colors of the source through only the blue gun. You are seeing yellow, cyan, green, magenta, red, and blue through the blue gun only. When you adjust the hue and chroma controls, you change the balance of those colors and you’ll see the intensity of the individual areas change with respect to each other–again, all through the blue gun only.
With a blue-only source, you’ll get no comparison and thus no change in intesity between, say, the yellow and cyan bars. They’ll all change in usison and thus defeat the comparison you’re trying to make.

That wouldn’t work because you need to have all the colors coming to the monitor. You could easily get a blue filter. The article below says a Wratten 47B is the one you want.

RAID-1 will have write performance equal to only a single disk. It’s read performance will be comparable to a RAID-0 two-disk array. RAID-0 speed will outstrip it by far if more drives are added to the array.
