Fixing colors

My camera started shooting in false colors for unknown reasons... Now my clips look a lot like you can see at minute 1.11 in this footage:
http://www.timandjoe.co.uk/Google-Street-View-Animation

Is this a "known issue" of digital cameras?
Not being able to fix it by hardware, I'd like to attempt a SW fix: I installed this plugin in virtualdub, which allows replacing single colors; but how do I know the color of a pixel? i found ColorPicker plugin, but it requires manual coordinates input...

Can I in some way save the palette of a frame in the "pseudocolor plugin" format?

The simplest way to pick color: hover over preview window and hold shift. You will see overlay window with decimal rgb values etc.

The image at 1:11 is solarized:



If this is what you have, it is possible it's because you enabled a "solarize" special effect in your camera. The only way to un-solarize would be to determine the color curves applied in the effect and apply the inverse curves with something like mt_lut. Not easy, and maybe not possible.

Not possible, I think. A solarisation curve maps colors in a many-to-1 fashion (two different input levels may map to the same output level), so you can't invert it.

Ah ok, you talked about the preview window of the plugin, not of virtualdub...

Thanks.
