Avisynth: Possibly reduce background flickering?

I ran some recent tests and I found that using BicubicResize instead of LanczosResize+MergeLuma(Blur(.2)) actually gives me a higher quality image and reduces the slight background flickering I was getting before.

Here is my old script:

Code:

Import ("C:\filters\functions.h")



AviSource("E:\Shrek.avi")

LegalClip()



GripCrop( width=528, height=480, overscan=2 )

GripSize(resizer="lanczosresize")



mergechroma(blur(1).blur(1))

mergeluma(blur(0.2))

SpaceDust()

FluxSmooth()

DctFilter(1,1,1,1,1,.5,.5,0)



GripBorders()

LegalClip()

SampleClip()

And here is my new script:

Code:

Import ("C:\filters\functions.h")



AviSource("E:\Shrek.avi")

LegalClip()



GripCrop( width=528, height=480, overscan=2 )

GripSize(resizer="bicubicresize")



mergechroma(blur(1).blur(1))

SpaceDust()

FluxSmooth()

DctFilter(1,1,1,1,1,.5,.5,0)



GripBorders()

LegalClip()

SampleClip()

Let me know your thought/results using this.

If your talking about when all of a sudden the video will go brighter then darker in certain areas then I would be interested in testing this to. I thought it was just my JVC DVD player trying to compensate when the movie got a little darker. I don't remember this happening with my APEX, but I also just started using LanczosResize too. Wierd. I switched to Lanczos because it gives a little sharper picture than BiCubic (.75) but if this new resizer is the cause of the flickering then I should go back to Bicubic.

Just so you know, when I switched to BiCubic I removed the MergeLuma(Blur.2)) line from my script. I figure that the loss of sharpness by not using Lanczos could be counteracted by not using Blur.

I was just compairing Bicibic to Lanczos because I don't use MergeLuma or MergeCroma.
