Is there something like "auto adjust" to quickly improve video light/contrast/color?

I just got a lot of somewhat low quality video files and I'm looking for a way to brush them up quickly. It doesn't have to be production quality, but just some basic adjustments for brightness, contrast, white balance,...

For photos there is some kind of "auto adjust" in almost all picture editing software that does a mostly decent job. So I was wondering: Is there something similar for video? Preferably in KDEnlive but I would also be willing to use any other tool that runs under Linux.

And yes, I know, that a manual correction will give much better results, but I'm lazy, it is a lot of material and I don't need perfect results for this particular project :-)
