[ACClarke]

thank's a lot for this
I will test it on some Manga stuff (bad NTSC->PAL)

[Koepi]

Very nice, will check it on STNG bad transfers...

Thanks & best regards

Can someone tell me what those settings do? I don't see any documentation anywhere :(

[WarpEnterprises]

unblend(clip, int "threshold", float "dthresh", bool "show")

unblend compares each frame to the previous and the next.

threshold is a noise threshold (~5). If a pixel is more different from the one in the prev or next frame it is not considered .

Then there is a calculation done which gives a kind of probability that the frame is a blend - that it can be "constructed" by blending the prev and next together.
Having a probability > dthresh (~0.03) will replace the current with next or prev.

You can check if you select a blended frame and increase dthresh until it shows it as blended.

Thanks for the info!

@people who use the plugin,
Could anyone of you provide a short readme, how to use this plugin?

[FredThompson]

It's also here: http://www.avisynth.org/~warpenterprises/

rePAL is there also and has a readme.

[Wilbert]

That's because I mailed them to WarpEnterprises :)

[FredThompson]

sparse homepage ya got there, huh?

[WarpEnterprises]

?? (somewhat cryptic)

[Wilbert]

I think he was referring to my homepage :) Anyway, I have internet at home since a few weeks. So, I will do something about it when I have some time :)

[FredThompson]

yes, I was talking about Wilbert's homepage.

I'm putting together a home for "dead" sites and translations to English. Would you please forward whatever notes you have?

Sorry to dig up an old thread, but this filter worked wonders @ default settings with some blended anime I had laying around.

Good show!

[WarpEnterprises]

As I have a backup of the AviSynth forum here is the post Bach deleted at the top.


unblend is a plugin based on warpenterprise's deblend algorithm and neuron2's decimate code, with YV12 support only. The aim is the same of deblend. The best usage is

avisource()
(smart)bob()
unblend()
decimate()

Of course you will need to play with some filters to achieve a smartbob, play with unblend settings - the default is unblend(threshold=5, dthresh=0.03, show=false) - and play with decimate settings.

will this filter unblur, I don't get what it does exactly. oh if it doesn't could someone recommend me a filter that does.

[Alain2]

Blur ~= within a frame, makes sharp edges becoming smoothes, over a defined radius

Blend = mix of 2 (ratio tbd, can be 50%/50% or others) or more original frames into 1, which can look like directional blurring on moving objects

What is the effect you want to try to revert ?

On anime, blending is very obvious, it looks like ghosted lines next to each other. That blurring, however, needs a sharpener and tweak to incrase saturation (and, tbh, a better source, you'll never get it looking quite like the top).

There's a quick anime guide http://www.techimo.com/articles/index.pl?photo=35

btw, repal() worked great for me..
