Hi Folks,

I'm new here and am looking for help brightening different parts of a movie and darkening other parts. I know how to use the filters for the complete movie, but have not found out how to do it at different levels on different sections of a movie.

Is there an easy way to do this in VirtualDub?

TIA for your responses.

Try the Conditional Filter.

Thank you, Cyberman, better late than sorry I guess. Video editing is after all only a small part of my photography hobby, so I actually spend very little time on it.

I have tried a few things since to correct this irritating exposure problem with no satisfactory results. The conditional filter is simply too cumbersome, too complex to use. I am dealing with an automatically adjusting exposure with my digicam (I wish I had a way to set exposure to manual but can't) and the self adjusting exposure drives me nuts.

Even the deflicker filter hardly has any effect.

If anyone out there is working or knows of a filter so set light values according to a reference within the video sequence, I'd love to know about it.

Thank you all in advance smile.gif

I´m searching for that too, now.

Maybe Donald Grafts Histogram filter will help, though it´s not temporal.
Perhaps some AviSynth filter can do it.
