BMPC Fixed Pattern Noise solution

Recommended Posts

First you need to record noise from the camera you are trying to de-noise from.. the technique used was recording with lens cap on at 600 iso, film gamma, 10bit. Then 150 frames of the noise was averaged into a static. That was done in Nuke with the FrameBlend node, which created the "fingerprint" for that specific camera. Then a subtract was done in flame using the generated graphic with the clip, but most NLE's have some way of taking 2 clips and doing a math operation. 

 

By adjusting the levels of the fpn graphic, you can control how much of the pattern you are taking out of the clip.

 

Hopefully this can help fix some footage out there while everyone waits for a firmware update.
