My latest script

My latest script for speed and quality

Code:

[AVISYNTH_STM_BilinearResize]

0=BilinearResize(^TargetWidth,^TargetHeight)

1=Undot()

2=Asharp(1, 4)

3=STMedianFilter(^S_FilterThreshHold, ^S_EdgeThreshHold, 0, 0 )

4=MergeChroma(blur(^blur_chroma))

5=MergeLuma(blur(^blur_luma))

6=Temporalsoften(2,3,3,mode=2,scenechange=6)

7=AddBorders(0,^BorderTop,0,^BorderBottom)

^S_FilterThreshHold=8

^S_EdgeThreshHold=32

^blur_chroma=1.50

^blur_luma=0.1

I do not like at all bilinear as I found a lot of aliasing effect on curves with it. This point appart, your script looks correct.

Perhaps it misses the usage of gripcrop in order to have the possibility of adding an overscan border.

Note: bluring can go up to 1.58, not 1.50. You can win a little more space ;-)

I'll give bicubic a try. I thought I read that bilinear was better for reducing the image size?

When I ran a test clip, I found my new script gave more compression that the MA script.

I have that with almost all my static scripts.

MA script is the best for visual results, not for space gain.
