DeDot kicks butt (and so does it's creator theJam97)

[LB]

I miss that guy. Anyone know if he's still developing filters? He made IT() which is one of the best ivtc filters and he's made dedot which is hands down the best dot remover and even has it's own built in rainbow remover.

Anyway, I'm an avid fan of this plugin. Here is the script that created the image below:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3dg.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\IT_v1.03.dll")
Mpeg2Source("J:\Sample.d2v")
DeDot(20,20,15,5)
IT(fps = 24, ref = "TOP", diMode = 2)

And as you can see, DeDot is meant to be run before any IVTC and anything else. It should be run immediately after opening the .d2v file. Also, another reason I'm creating this post is because I've seen many people try DeDot() without any settings and get almost zero results. TheJam97 is japanese so he never made an english readme. But generally the settings I pasted above work really well.

And finally, the results. I just love this screenshot. Don't you? :)

the dedot settings you have there are the defaults... :) most likely if there's no results it's because the source has been processed (ivtc/deint) before dedot gets a look at it.

it's a bit of a coincidence - i only got this filter today and i'm liking it a lot too. it handled the crawls on FMP fumoffu really well - not completely gone, but muted to the point where it's not visible on a teev viewing through component leads (which is all you need for DVD). can't wait to try it on scrapped princess.

A quick little trick to remove any stray dot crawl is to load up MF's HQDering and apply it very lightly. It will remove any stray crawl since most of it occurs around edges.

I wish HQDering was updated and speed-optimized.

I think the creator intended camembert to be the replacement.

[Chainmax]

Well, mf didn't say anything in the Camembert thread about its intended use, but I think it's much stronger than HQDering. Besides, Camembert also has a deblocking mode.

I actually gave Scrapped Princess a try and experienced a "falling off the chair" effect meaning the filter performed really well. Granted that it doesn't work that well on moving picture and occasionally it produces some back dots there too but the end result is still worth it. Now if I can get IVTC working there too...

Is this filter designed for NTSC only? I remember trying it before and getting nowhere (and possibly even weird artefacts - I don't remember exactly) with a PAL source.

Hope you noticed this:

Worked fine with me (NTSC material). Haven't tried with PAL material but I cannot see any reason why it wouldn't worked with PAL too.

The periodicity of the noise is different. Imo, for ntsc you need to average two fields and for pal four fields to get rid of the noise.

I found a Translation of the ReadME DeDot.txt
Avisynth Plugin

DeDot (DeDot 0.3) : thejam


It reduces DotCrawl and Cross-Color. Maybe.

Changes
0.3
debug Check Cross-Color more strictly.
0.2
debug Remove green points flickering on the upper right corner.
debug Reduce garbage.


Requirements
MMX2 CPU.
Only used for interlaced materials.


Usage
Write in your avs file as follows:
LoadPlugin("path\De.dll")
# your sources and other filters
DeDot()


Parameters
DeDot(luma2d,lumaT,chromaT1,chromaT2)
default 20,20,15,5

luma2d
Spatial luma threshold.
This value is lower, DeDot detects more pixels as Dot Crawl.

lumaT
Tolerance of Temporal luma signals.
This value is higher, DeDot detects more pixels as Dot Crawl.

chromaT1
Tolerance of temporal chroma signals.
This value is higher, DeDot detects more pixels as cross-color.

chromaT2
Temporal chroma threshold.
This value is lower, DeDot detects more pixels as cross-color.


Warning
Filter before deinterlace and resize.
If pixels are mixed, difficult to detect.

I don't know well, but different TV tuners and Capture cards have
different appearing patterns of Dot Crawl and Cross-Color ?
If so, you may not get good results depending on environment.
