    Healing dead pixels?

    Navarro Parker Level 3

      I was reading about this script for Nuke that can heal bad NaN pixels in 3D renders:

      Is there anything similar for AE? There's no Content-Aware Fill for AE yet... is there?

          I can think of a few ways of solving this that might or might not meet your needs.  Of course you could just key out the dead pixels, and have a bg layer that's offset or blurred.

           

          Alternatively Re:Vision's RE:Fill is a (slightly) more sophisticated approach.   Either of those would be sufficient for solving single dead pixels.

            I find it hard to believe no one has requested Content Aware Fill for AE in the years Photoshop CS5 introduced it.

              That is the wrong conclusion to jump to.

               

              Algorithms that are easy (or even trivial) for still images are often much, much harder for sequences of images (i.e., movies), since still-image programs can make arbitrary decisions about image processing without considering how the same decision must be made for a very similar frame that is adjacent in time. Just think of all of the bad rotoscoping work that you've seen where edges "sizzle" because of small deviations from frame to frame... even though each frame seems fine on its own.

               

              Content-aware processing for video is a very rich area for research, and our best people are on it.

                The product demo videos of Mocha Pro Remove and the old Mokey make it look soooooo easy. I saw a video of it on the internet, so it MUST be true.
