Interesting Avisynth resizing thread at doom9.org
 
http://forum.doom9.org/showthread.php?s=&threadid=70734

Im at my office now, so I will check that this weekend. :)

Do use your skills to check it out! A little over my head, but it does look interesting.

In that thread, he claims: "- moving areas of each frame are softly resized and blured"

How can you apply filtering to a moving object, if there's no function in AviSynth that will give you a "sector" ( or what we already tried a while ago, by splitting a frame in quadrants) :!:
I don't see any function on that script that can apply blur to a moving object, without applying to the rest of the frame.
Or maybe I'm still not fully awake :lol:

"I think" its something with "maskedmerge" or at least its logic.

Do you remember my PN some time ago dealing about motionmask testings?
You also answered there something about separation of the image in quadrants for motion detection.

I once did several days some testings using motionmask and MrTibs MADmask (only avs 2.0) ... it could be a way, but the thresholds of motionmask for example are very difficult to set so the Edges i.e. on static objects won't get blurry too!

hi Inc,

that sounds like a long ago snip froma thread, regarding the MA script
imrovements on motion estimates on a block-by-block bases. I think there
was talk about this long ago, in seeing if someone would create such a
filter (or .avs script) for this. Way too much reading in my days here.. I don't recall whatever became of this. Oh yes..
it was proved to be too slooooooow hehe..

I think that's what you're refering too :lol:

You're right vhelp :)
It's buried deep deep in this forum, when I tried slicing each frame into quadrants, and doing blur only on the parts that had motion.
It worked, but it was SLOWWWWWWW :lol:
The script I did, will be perfectly useable in the year 2010, when we are running 20Ghz CPUs :rotf:

:mrgreen:

I knew it !! Time for more coffee and reading :roll:
Yes, the good old days of testing testing testing.. debug, debug, debug..
And, there might be some new things coming up soon :lol:

Yep! Its damn slow! :)

But I think the logic, to play a little with "masked edges" and performing a bulr on them would be quite interesting.
I don't think we gonna fall in love with exactly that script, but very interesting "views" in it

By changing the debug to 1 or 2 you can see which parts are motion or edge masked .... and for ma that could be a motion mask where it could perform a blur

@ kwag
Do you still have the script? Would be interesting to try it out. Even though it's adapted for the year 2010+... :wink: :D

@ incredible
How do you get the HybridFuPP.avsi to work? Could you please post your script? I'm getting an error in VirtualDub saying 'There's no function named "MotionMask"'. What values do I have to use for resizing? Now I simply put "HybridFuPP(480, 480)" but I'm guessing that's wrong :?:

rds_correia 02-16-2004 02:41 AM

Aha!
I think we need to download some sort of filter(maybe MotionMask) in order to use HybridFuPP.
But that you will find in doom9 thread audioslave.
Check it out again buddy.
C ya

incredible 02-16-2004 05:57 AM

Please read the thread there carefully cause I exactly got that error in vdub too, ... You need to download a special version of masktools.dll.
The download is mentioned there.

:wink:

And stay updated! As he every day releases updates of his function.

It's buried deep deep in this forum. Do a search for "quadrant", and you'll find it somewhere. I can't even remember where it is :lol:

audioslave 02-16-2004 12:58 PM

@ kwag
Still searching for your script... a LOT of posts to read through. :D Don't know if I have the patience to read 'em all. Thanks anyway. :wink:

@ incredible
I found the correct version of MaskTools and now it works like a charm! 8) :D

Thank you guys!

incredible 02-16-2004 01:32 PM

Watch his pics there and I can duplicate them!
Very sharp static parts and on the other hand a bit blurred moving parts. :D

BUt ..... its sloooow! :(

Found it :!:

Original idea was ARnet_tenRA's ;)

New version of this function/filter: 0.6b.
Looks by faaaar better than versions 0.4b and 0.5b. Give it a spin. :wink:
I encoded "Underworld" with this and got CQ70,55 for this 2 hours movie - with 128kbps audio :!:

incredible 02-25-2004 04:18 AM

Did you recognise any speed-improvements? Cause thats the reason why I dropped it "till now" .... sloooow, even on my machine :(

audioslave 02-25-2004 04:42 PM

Well, I don't really know about that... I don't think it's that slow at all. The whole movie took me about 4:45 to ancode on my AMD 2000+. Not that bad I think. :wink:

bigggt 02-25-2004 06:39 PM

Does anyone have a link to masktools 1.4.9 because i can't seem to find one

Edit-I finally found it :D

incredible 03-02-2004 01:14 PM

Well I installed Fupps new Version of that function and I say:

:jawdrop:

Its faster then the old one (no probs at 352x288 and about a little less then realtime on a 480x576 ... on my machine)

To the left the treated frame using HybridFupp and to the right the original.
Its a 480x576 capture.
What I discovered is that with setting "low" much noise went away (not seen in the pic but its true) and --- I its REALLY funny --- only the motion objects did get an unsharpen kick.

Look at the Boat at the faces of the couple! And on the other hand the little details on the top of the roof of the house right... they've been kept!!
