Hi,
I have this old footage where the lighting used was too bright and it washed away the details . I tried using all sorts filters from histogram, levels, and gamma but cant get the features. All it does is darken the image. So I tried by saving in bmp and use it as logo and merge the footage with the animate bmp of the footage. but failed as it gave a rather plastic looking image and did not even produce the desired enhancements. Pls help me.

You might try Donald Graft's Hue/Saturation/Intensity filter.

May the FOURCC be with you...

Like I said it only darken the image but does not bring out the details. To describe the image I would say the light was too bright that the facial features disappear ( faceless at some point ). Tks

It's extremely hard to reintroduce details into a video that aren't there to start with, there may not be a way to repair what you're talking about at all. All I can say is to get extremely creative with the filters and hope for the best. sorry I can't be more helpful than that.

Have you tried the white balance filter by Jim Leonard? tends to work nicely most of the time for me, but like I said, if the details just aren't there, they just aren't there.

I might also help, if your source is analog, and you still have it handy, quite abit more than post capture filtering, to re-capture the original footage after adjusting the color and gamma settings in your capture device.
