Some deblocking filters do not work.

Avisynth 64
Not working Deblock_QED. The preview window does not open.


Avisynth 32
Not working Deblock_QED. The preview window opens, but does not see the difference between the right and left windows

Not working AMDCT. The preview window opens, but does not see the difference between the right and left windows

Works fine here, seems like an issue with the source.

Works fine here.
Depending on the the source the default values might simply not showing much of a difference.
For amDCT set Smoothing->Quant to 31 that should show a difference.
For Deblock_QED using Deblock_QED(quant1=40,quant2=40,uv=1) should also be visible, but QED is meant for light deblocking so depending on the source differences might not be that easy to spot.

With the same source preview window working on Vapoursynth.

This filter works with the above settings, but the difference is hardly noticeable.

This filter also works, but the difference is hardly noticeable.
(quant1=40,quant2=40,uv=1) there are other parameter names - Edge, Inner, Chroma Deblocking, border, block

That does not really say anything.
Since I can't reprodcue the issue my guess is that it is an issue between the source filter and the source.

About deblocking filters in Avisynth: So everything works fine and the filters simply do not work for your source as you hoped.
