VCD MPEG-1 deblocking script?

[ChiDragon]

I have a movie that's only available on VHS and VCD, so I'd like to try watching the VCD on my HDTV (lower vertical resolution but much better color than the VHS).

Does anyone have a good script to do deblocking and graining?

a vcd better than (retail) vhs..i'd be curious to see that
You know you can enhance colors in software

Yeah, I'll take a VHS source over a VCD any day. Anyway, for deblocking VCDs I use DeBlock_QED. If the default isn't good enough you can strengthen it.

Or others, take your pick:

I attempted to match the colors with ColorYUV when I did the capture, but still came out with weird tints.

Thanks for the links.

(And if anyone recognizes the film, there was no point getting into it in the OP, but while there is a DVD release I want the open matte version.)

The VHS one looks better from those stills.

To me too, the VHS one looks sharper and more detailed but the colours bleed a little... maybe you could align and sync both versions perfectly (syncing should be possible if you load them side by side in an avs script and go through it with VirtualDub or something to see where potential de-sync occurs, for aligning maybe convert to greyscale and overlay both in substract or multiply mode and shift around until it fits) and then combine the Y value of the VHS and the UV values of the VCD? Something like YToUV(clipU=VCDRip.UtoY(), clipV=VCDRip.VtoY(), clipY=VHSRip)

Possible (some resizing is needed) - but there are easy fixes for the VHS chroma too. Hard to be sure from that sample, but it looks like it needs moving up by a few lines, which would solve most of the visible problems. A bit of denoise+awarpsharp on the chroma might help too.
