Since I don't like the blockiness of point resize to retain all the color information, I decided to try this method where I resize the luma with the best resizer I know of and resize the chroma with point resize. I used the following Avisynth script:
LoadPlugin("nnedi3.dll")
a = AVISource("RM2Video.avi")
chroma = a.PointResize(a.width * 2, a.height * 2).ConvertToYV24(chromaresample="point").ConvertToYV12(chromaresample="point")

luma = a.ConvertToRGB24().nnedi3_rpow2(rfactor=2, nsize=4, nns=4, qual=2, pscrn=false, cshift="LanczosResize", ep0=100).ConvertToYV24(chromaresample="point").ConvertToYV12(chromaresample="point")

last = luma.MergeChroma(chroma)
return last
This script runs very very slowly on my computer, but I think the output is worth it. Here is an example of the output: http://www.mediafire.com/?1a0ncg1i2mchypn

While I know you mean well, this just sounds too disgusting for me. Please choose better comment next time.

I love you. Seriously, you're one of the best encoders TASVideos has ever had! Edit: Upon further investigation, it appears there is a few... catches with this filter. I retract my comments.

No offense, but I think I prefer the point-resizing method we are using. I don't really like the blur.

Yep, to each their own. I sure don't like the blockiness, as stated in my first post =p. I think this blur is cleaner and better than any upscale I've seen on fly, and all the color is there!

Here is an example of this filter at work. Mind you the image is what the encode will look like as the color in those images is fixed to be in 2x2 pixel blocks (except the original, obviously). The links are in this order: Original 2x 4x 8x http://img703.imageshack.us/img703/7060/temp0.png http://img708.imageshack.us/img708/2678/temp0o.png http://img838.imageshack.us/img838/7060/temp0.png http://img831.imageshack.us/img831/7060/temp0.png

I mentioned this to Aktan previously, but I'll mention it again here: I think the above results are unacceptably blurry (for me, not necessarily from a site perspective) for not much benefit. Considering the additional processing time I don't think it is worthwhile.

Here is a complete example using this resizing on the latest Rockman 1: http://www.mediafire.com/?eb3po3pqiew0ylb
