This is a puzzle... now i am puzzled :) (Strange noise)

[Q-W-Y]

Hi,
I fight with a strange noise. I have tried many filters, but it still results in soft color spots...
Could you help me please?

Cut from original DV source (5 MB) (http://www.ceskyinterier.cz/files/QWYforumDoomDVcut.avi)

btw Is there any way to increase resolution of this video?

Thank you very much..

To clean this I would recommend either SmartSmootherHQ or maybe one of MarkFD's Deen filters. SSHQ is for the VDub family, while Deen is for AviSynth. Also be sure to take off any prior filters before trying SSHQ/Deen. As for the noise at the edge (particularly the left side), your best bet might be to just crop off the few bad pixels.

Also, you could increase the resolution with any of AviSynth's resize functions (BicubicResize, etc.), but the real question is why? It will just result in a larger file after reencoding, and a greater loss in quality when played back at a different resolution than whatever you resize it to.

MarcFD's site is here: http://ziquash.chez.tiscali.fr/
SmartSmotherHQ can be gotten here: http://neuron2.net/hiq/smoothhiq.html

@QWY:
- why is this Video uncompressed YV12? (explaining its large size)
- why is it deinterlaced?

also, I do not see the mentioned color spots. (please explain mire)

also, for better hints, a UNPROCESSED file, as it comes directly from the cam, is needed!

FYI, colours (except maybe green) will always be blurry on a 1 chip.

i'll have to see a chunk of the source DV (remember to have "direct stream copy" set in virtualdub).

maybe limitedsharpen could be applied just to the chroma?

btw, there's some crud on your lens - look at the highlights blowing out on the foldbacks on stage - they go off to one side slightly. this might have a noticable effect on chroma, but probably not (there seems to be a little bleeding off the blue keyboard).

Any ideas Scharf?

I found this:

bob()
temporalsoften(3,8,12)
separatefields().selectevery(4,0,3).weave()

being useful

the output is interlaced. do NOT deinterlace it.
encode it interlaced.

Why? Interlaced takes more bitrate...

[scharfis_brain]

Interlaced looks smoother and crisper!
Encode for DVD!
