Removing a light leak in camera

[Eugene Lehnert]

Hello-

I’m trying to fix some wedding footage I shot with Nuke. There was some light leaking into my camera. Any ideas how to reduce the flashing?

I tried averaging frames together and blurring it then subtracting it from a blurred original shot and adding the result to the original but the effects last over too many frames.

Any ideas?

Thanks

hi there,
have you tried the “curvetool” ?
you can analyse the brightness difference and use these to drive a color correction.
and i think in the sapphire plugin package is somethong like “FlickerRemove”. ths could help to.

hope this helps
cheers,

I tried the Flicker plug-in on the Flame but the strobbing is too long I think. I’ll look into the curves function. Maybe that will work.

Thanks. I tried taking the average intensities of a clip and subtracting it from a good reference frame and adding the results to each channel. The clip looks slightly better. Is there a way to use the curvetool to control the blacks, gamma and highlights? Is there a way to drive a levels tool this way?

To control the blacks, gamma and highlights I would have to isolate different parts of the image and get their averages to drive a grade node I suppose? My shots has a lot of movement though. This might prove complicated.

Hey there 🙂

you could try Gentle Fury’s Matchgrade-Gizmo. It also is capable of flicker-fixing. Hope it helps.
