Removing Hot Pixels Effectively
on Jan 25, 2016 at 12:51:20 am

I’m coloring a short film shot on RED, which has a number of hot pixels in some of the shots, and I was wondering if anyone has a good method for removing hot/dead pixels. In the past I used a freeware plugin in FCP 7 called Dead Pixel Remover that worked a treat. I’ve yet to find anything that really works in Resolve.

I’ve tried making my own masks and blurring them, which just creates a visible smudge in the shape of the window. Windowing and qualifiers to try and darken or lessen the pixel, in addition to a blur, still doesn't really work. I have Sapphire and used a combination of windowing and S_GrainRemove, which works for some smaller pixels, but doesn’t cut it, or looks too noticeably blurry for larger ones.

Is there another tool, or method, or plugin that works better? Something that actually samples adjacent pixels and works like an active clone tool (instead of just creating a smudge over the pixel)?

I’d like to keep it inside Resolve if possible and I’m not sure how using an outside program like PFClean will work with my workflow. Because I’m using R3D files and need that latitude, I don’t want to take those into another program and have to export out to a Quicktime or TIFF or DPX and lose my camera raw.

Any ideas are much appreciated.
