Suggestions on how to "un-blur" a DV file ?

[Zetti]

Hi all,

I have a very nice concert music on VHS, but it's say a 3rd or 4th generation tape, colors are strong and blurred

I have captured it hrough a ADVC-100 device, so it's on DV format suitable for editiing;

Does anyone have an idea on how to try to improve it when converting to MPEG2 ?
OK, OK, I know miracles don't exist.....

Maybe a good setting at Premiere Pro ?
Or at Canopus Procoder 2.0 ?
Is there any kind on "un-blur" filter in these sw's ? I think so;

I don't use to do it, so I am not experienced on that;
Let me say that the blur is very typical of a high generation VHS tape, so you experienced VHS converters know what I am talking about;

Thanks,

Zetti

I think I know what you mean. Color 'bleeding'. Seems there is a VD filter to help, but I don't remember the one right now. I never had much luck, the only thing I found was to lower the color saturation, then you have very washed out colors. I guess once it's screwed up, it's hard to fix it.

Sorry, VD=Virtualdub. You might do a search for 'Virtualdub filters'. There might be something to help there.

Thanks, I've tried the Sharpen filter on Procoder, after 25 hours of encoding I'll see how it ends....

Here's a script I'm using with CCE & AviSynth to transfer an old football game from VHS to DVD...

AviSource("reallycrappyblurrybleedyVHSsource.avi")
Tweak(bright=-7,sat=0.90,cont=1.07)
_2DCleanYUY2(0,6,2,2,0,4,4)
ComplementParity()
SeparateFields()
odd=SelectOdd.Convolution3D(0, 32, 128, 16, 64, 10, 0)
evn=SelectEven.Convolution3D(0, 32, 128, 16, 64, 10, 0)
MSharpen(65,115,mask=false,highq=true)
Interleave(evn,odd)
Weave()

I'm capturing lossless to huffyuv, then running the script thru VDubMod and resaving to lossless huffyuv, then encoding the outputted file. Not my normal routine, but I get a better looking MPEG2 file for some reason when I'm feeding my encoder an AVI file that's already been processed as opposed to letting it filter on the fly durring the encode process.

I'm going to be re-evaluating some things after this.

Thanks, I'll keep your script as reference;

I got a good result using the SHARPEN filter on Procoder 2.0; actually the final file is TOO sharp, but better than the original one;
