I CAN see a change between before filters and after filters before compression to jpg. Any suggestions on what I can use to remove the rainbowing and/or extra noise?

ConvertToYUY2()
TemporalSmoother(strength=3,radius=7)

Your unfiltered source looks pretty good to me. I'd encode that unfiltered especially if you're using a good detail codec (i.e. xvid). It looks pretty clean IMO.

The JPG compression is making it look better :P
The source is hoooooooooribly dirty.

I disagree. I may be biased because I prefer detail to smoothness, but look how much more detail there is in the source picture, I especially notice the increase in detail in the upper right area on that blue surface. Throw a nice detailed source like that at Xvid and you'll get great results IMO. If you really want to smooth it out, I think the filter combination you have is working pretty well.

I think Deen("a2d",5,10,30) might do a good job for you in place of Vague denoise. Of if you wanna use them in conjunction, maybe just lower the strength of vaguedenoise and use Deen("a2d",5,5,30). This should smooth the colors out a good bit, and help the rainbows a lot.
I'd also recommend using a temporal cleaner that can operate in yv12 colorspace. It's a shame to do a conversion just for that.

My choice would be:
Mpeg2Source("H:\Iria Zeiram the Animation\PROJECT -- 1.d2v")
Telecide(order=0,guide=0,post=0)
Decimate(cycle=5,quality=3)
VagueDenoiser(threshold=3,method=1,nsteps=6,chroma=true)
Fluxsmooth(5,-1)
i've removed the useless conversion, reduced the vaguedenoiser threshold as it's a bit high. Finally fluxsmooth remove the temporal noise that vaguedenoiser can't. On my own tests, these two filters seems to work well together.

I like deen's a3d in conjunction with vaguedenioser myself.

You've gotten rid of a lot of noise but other than that I really can't tell how well the filters worked because I don't know what it looked like before being compressed as JPEG. Try using PNG just so everyone viewing it knows for sure there aren't any JPEG artifacts.
