Well, to explain how I made the second effect, think of it like this:
When you want to use a green screen or blue screen, you have to 'key' it out. You generally select a color that would be on the screen to made transparent, and then you increase/decrease range and feather to make it ideally so only and all of the screen is taken out. But if you OVER key, as in you make the color range too large, then it bleeds into making your set transparent. That idea sparked me for this effect. I made the range of the chroma key to include the main lighter colors of Mr. Invisible.
In this way, only parts of him (and the rest of the set) are visible, but when you place that video over a background of the same thing (without Mr. Invisible, as is well known with method 1), the only thing that appears to be partially keyed out is the walking minifigure, in this case.

In a phrase: made from bad chroma-keying. 

As for that tutorial, Noodle, it is an effect I've seen before and really liked. I'm not actually needing invisibility for any project as of yet, this was something just to try out once I had that idea of using software in a new way.]]></content>

But I probably won't use it, 

A) Because I can't

and 

B) I prefer on set effects.]]></content>

			<content type="html"><![CDATA[Interesting... I'm still not 100% sure how you did that, but I agree, the second did look a little more "realistic" and definitely less amateur-ish.

As far as transparency tutorials, I used [url=http://www.digitalvideofuel.com/predator2.htm]this one[/url] a while back for a live action project. It's a much different look then what you seem to be going for, but perhaps it'll make you think of something else to try.]]></content>

This is n idea I had a little while ago, and I just wanted to test it out. I formalized it a little more, trying out the generic method of invisibility, but the main point was to try "Method 2" with the chroma keying. I find it didn't turn out quite as I had hoped, but it still would work. Different chroma keying software would have different outcomes with this effect (this time I did it straight through Final Cut Express), and just by coincidence, I think it might work better if I were to try through iStopmotion (though less manual controlling of the keying)...

Anyways, if anyone else has a general (non frame by frame editing version) way to create invisibility, I would be curious to hear about it.

Oh, and yes, Moo-ack.
