Levels Correction

Can anyone provide me with proper levels correction for this? My monitor's colors/brightness/contrast are so screwed up (monitor is 8 years old) I have no way of doing this until I get a new monitor. Thanks!

RE: Levels Correction

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.

RE: Levels Correction

I used the method scharfis_brain gave on a clip I have. The VirtualDub filter reads: 0.0-0.83>1.00>0.00-1.00 RGB How do I rewrite that for the levels filter in avisynth?(I thought I needed intergers except for the gamma?

@scharfis_brain Thanks. Now that you've told me its's obvious:) It just never occurred to me that the values came from the box not the line that I posted.
