Removing Dead Pixels

Hi, thanks for everybody's help so far.

One on the cameras the footage was shot on has dead pixels (which show up as white spots). Its a dance pice in a theatre so the background it black. Was wondering if it was possible to set a qualifier on white pixels so I can turn them down. Tried but no luck. Cant use hit them with picker, if I zoom in enough to get then they are off screen (shame you cant scroll around window when it is zoomed in.

Any ideas?
Ben

You can use the middle mouse press and drag to scroll around the image.

[Ben Edwards] "Was wondering if it was possible to set a qualifier on white pixels so I can turn them down."

Stuck pixels don't move around (but moving objects in the picture content obviously complicates the correction) so what I normally do is crate a teensy weensy power window and set a blur so that the pixel is naturally migrating towards whatever the adjacent pixel values are.

This approach breaks down whenever an edge crosses the qualifier, so it requires a keyframe/tweak. So the technique either works a treat or (depending on picture activity) is more trouble than its worth.

However, it doesn't require any plugins or roundtripping pass-back and forth.

I use your power window technique as well, but I usually do a noise reduction rather than a blur. Blur is less resource intensive (won't slow down the machine) but NR will be less visible.
