PixieDust on 1080p videos

[ghstkhp]

hello i am trying to use PixieDust to make video more compressible but it doesnt work(message: "Error: System exception - Access Violation")

Note:i can use PixieDust on videos with lower resolution.

code:
"
LoadPlugin("DirectShowSource.dll")
LoadPlugin("LoadPluginEx.dll")
LoadPlugin("DustV5.dll")
DirectShowSource("input.mkv")
ConvertToYUY2()
PixieDust()
"

does anybody know how to solve this or is there another plugin to do the same job?

I believe that Pixiedust is an Avisynth v2.0 filter and quite old, also no source is available and so could not be fixed.
Any spatial/temporal smoothing/degrain filter will make your clips more compressable.
DCTFilter is intended to increase compressibility not sure how well this works though.

I personally like to use FFT3DFilter for such, with a gentle sigma of about 1.4->1.7 (way less than most people seem to use).

EDIT: HQDN3D (Hi Quality Denoise 3D), is a pretty fast filter, might be worth a try (FluxSmooth also fast I think but I dont really use it).

If improving compressibility is your main goal, you might wanna check out this post by Didée regarding the functions "SPresso" and "STPresso" :forum.doom9.org/showthread.php?p=1551871#post1551871

I'm an avisynth dunce - to even post on this forum raises my bloodpressure :o - but my hunch is that it could help you.:)

That thread really ought to either be destickied, obsoleted and remade in a modern fashion, or obsoleted through a topic edit like slapping a "[VERY OLD]" tag at the very start of the topic name.
Because while it's not wrong information, it's been ten whole years since the information was up to date with the methods used nowadays.

And if things haven't improved one bit since then, then I would be very much surprised.

Young man, if that filter was good enough for your grandfather, it's good enough for you. Now be quiet and eat your Convolution3D.
