On my calibrated monitor, the "original" images have much better color/tonal values. You've cooked them in the "restored" versions, and they definitely have illegal color values (for NTSC or PAL video). This is likely due to using a consumer LCD monitor with out-of-gamut color settings (fooling your eyes), and a heavy hand on the color knob (you trying to compensate for the monitor, and not really flaws in the video itself).
Your attempts to remove noise appear to mostly be using basic blur methods, which also lose a lot of the crisp detail on the original versions. There are some better NR methods we can use.
For color correction, Adobe Premiere Pro is an excellent tool
For noise reduction, Adobe Premiere is a joke. It will just ruin quality further. Never use it.
Same for Adobe Premiere audio filters -- lousy, lousy, lousy!
From what I can see, this restore project could avoid Adobe Premiere entirely. I think you need four key things:
1. Slight saturation boost.
2. Slight chroma noise reduction.
3. Noise reduction, temporal method A
4. Noise reduction, temporal method B
All of this could be accomplished in VirtualDubMod (not VirtualDub -- VirtualDubMod).
Can you cut off a small sliver of the original MPEG file (assuming this is an MPEG recording), and attach it to a post? Something less than 16MB in size. Then I could reply back with very specific settings.
If you want to learn even more advanced filter work, there may be some good Avisynth NR filters, for MPEG block/mosquito noise.
Also, please remember to attach images to forum posts -- don't link to images hosted on those photo/image sites, because those are not permanent. Read more here:
