Don's test is excellent, and the comparison gallery he set up is a tremendous resource. I have it permanently bookmarked on both my computer and my phone - and would recommend that everyone interested in such things do the same.
4'x4opal diffusion
I also agree with others, the steampunk set video doesn't really go a long way of showing the nature in variety of shadows created by various diffusion materials. In fact I'm quite sure the camera was on the exact same axis as the light itself, except the light was raised.
Opal diffusionvs frost
Hi,Don McVey from London did a pretty extensive test of every lee diffusion filters: http://donmcveydop.com/lee-filters/
Almost what would be more informative (and boring) would be to throw a 2D shadow on a white wall from a black cut-out shape lit by a lamp with different degrees of diffusion on a 4x4 frame.
Trouble with a face is that some are rounder and smoother than others - for example, a hard light on a baby's face almost looks like a soft light.

Opal is just thinner and lighter so it diffuses less than a heavier material. It's almost like a frosted shower curtain effect, similar also to a 1/2 Soft Frost.

It may help you. As David Mullen said, when you compare 251 to Opal Frost, same light loss but a lighter diffusion for Opal Frost.Hope it helps.

But one thing that I find interesting though. If you put a beautiful woman (or man) in front of any light, he or she will always look great anytime whether it be a match stick or a soft sun.
Argh! What a waste :( the particular framing they chose for that (and the distance of the diffusion from the subject it looks like) makes it damn near impossible to judge the actual shadow qualities of each particular diffusion.

If you have to compare this 2 diffusions: 215 vs opal frost, which I think they diffuse the shadow very similar, what would be the difference in the quality of light throught it?
I agree with Mark. While well intended I thought they should have used the same size sheets of diffusion in front of that 2k for accuracy. Also noting what happens when the diffusion is a foot away or 4 feet away from the light. Or something like that.
Opal tends to rattle in a breeze though, it is not as soft and flexible plastic material as 1/2 Soft Frost and it is not as rigid as a heavier plastic diffuser.
"Trouble with a face is that some are rounder and smoother than others - for example, a hard light on a baby's face almost looks like a soft light"
I don't think I said that. That would be a little dramatic. But in some shots they used approx. a 4x4 piece of diffusion and there are others where they used what looked like a normal sheet or scrap of diffusion. W all know when a light goes through diffusion, the diffusion becomes the source. The hardness/softness changes and so does the wrap around the subject depending how translucent or opaque the gel is. They easily could have kept the diffusion the same size for a true comparison at the distances they established. I don't think that is too much to ask.
Hate to use this tired phrase, "It is what is is." Someone took the time to set his up and attempt to help people less learned out. Sorry if you view it as a total fail.
