Can one translate this into: "I am just too lazy to do the levelling myself" ?!? anyway. - open that video in VDub. - add the levels filter - enable the preview. - set the gamma to 5.0 - adjust the black-level slider until the first pure-black pixels show up - set gamma to 0.050 - ajust the white level slide until the first white pixels are passed through - set the gamma to a value around 1.0 (+/- 0.2) that's it.
