Hi.. I love the new filter TomsMoComp, but i try to find the best and i have noticed this problem with the SearchEffort

The first picture is with TomsMoComp(1,0,1)
"0 being practically just a smarter bob" (in readme.txt)

look the edge of object (rooftop), the edge is not clean
same result with SearchEffort 15,20,25 etc...

why i have best resultat with SearchEffort "0"

Thx for you help!

I can't see the image but I'll bet I can guess. There seem to be increasing artifacts at SE levels > 5 so I recommend SE=5 for almost all purposes in Avisynth.

That is especially true I think for noisy pictures and maybe those with video text overlays.

Did you try SAVE AS.. for downloading picture

and yes my source is noisy (Cable TV) and with SearchEffort 5 my probleme is not 100% resolved because I can see little artifact on edge etc.. The best result is with "0"..

But what do you mean about "smarter bob"

Thx again

"smarter bob"..

Pardon my sloppy terminology there. In DScaler we've somewhat gotten into the habit of referring to any deinterlace method that relies only on a single field as a "bob" method, even if it does more than line double and doesn't even bob up and down much.

At SE=0 TomsMoComp uses an edge based line averaging technique to try to preserve diagonal lines somewhat, avoiding the stair step jaggies sometimes seen on line doublers.

At SE=1 or above it starts to also look for useful info from the prev and next video fields.
