Does anyone know if this filter exists for VirtualDub? I'd think since JPEG and MPEG use somewhat similar compression (i/DCT) that maybe it might be a good way of repairing some slightly artifacty videos (not real great for severe artifacts unfortunately).
also, nice filters in PSP are the Edge and Texture Preserving Smooth (edge for cartoons and such, texture for most else), Clarify and Automatic Saturation and Contrast Enhancement filters.

Well, about deblocking and artifacts ffdshow performs similar tasks and is open source. Some time ago I've been asking for a port of them as Vdub filters with little results. There is some kind of alpha filter but it's a complete port of ffdshow and it works in YUV.

| QUOTE | | Well, about deblocking and artifacts ffdshow performs similar tasks and is open source. | that's fine for deblocking, but the artifacts I'm talking about are the edge litter (kindof looks like an intentional paint stippling effect, except it's only because of the way it's compressed, I'm guessing it's what's referred to as ringing maybe) that JPEG and MPEG inherently have (if set at low enough of a quality level or bitrate, which ain't that low, really). from what I think I read a while ago (therefore probably wrong) the artifact I want to try to fix is caused by just the I frame, where the macroblock noise is because of the inter(intra? P and B at any rate)frames and motion vectoring
speaking of FFDShow, the latest build has a DScaler panel in it, does anyone know where to find DScaler plugins for it?? they're either not on DScaler's home page, or just incredibly well hidden, and I have used goggle (by way of copernic [hey, searching 10 different search engines at once is always a good thing]) to search elsewhere.

and while I'm at it, is there any word on a deconv filter yet? I've been using the standalone one alot more, recently, and I really think it needs to be able to determine the best method of deconv automatically somehow, right now, it takes way too long to deconv once, but when you pick the wrong method it can seriously do BAD THINGS© to a pic, then you have to go through and re-deconv again, taking another very long time.

The source is in CVS page at ffdshow´s page. Ffdshow also has ringing remover. Did you try using autodeblur from autoquant? It performs blind deconvolution with amazing results!!!

| QUOTE | | Ffdshow also has ringing remover. | But it doesn't help if you want to remove ringing while reencoding something (and yes I know it's not really a great thing to reencode lossy to lossy) instead of just playing it back

You can use ffdshow features thru avisynth with directshowsource comand. BTW there is a ffdshow vdub filter but you need to compile it and i never tested. I think deconv is on its way, one of these days we'll have a nice surprise!! Look into restoreinpaint page at sourceforge. |
