In Depth: Repairing Damaged Pixels
Updated March 20, 2015 10:02pm PST – Added BG Pixel Blaster for FCP X
First, lets get semantics out of the way. The term damaged pixel refers to several types of damage that can be recorded on a camera. The damaged pixels I’m referring to in this article are often caused by damage to a camera with CCDs or CMOS sensors. The damaged pixels can be white, black or sometimes even colored, but they are caused by different problems. I’ll try to explain this as simply as possible.
Dead pixels or burnt pixels happen when all three sub pixels (red, green and blue) are permanently turned off in the camera. They show up as black in the footage.
A hot pixel is when all three sub pixels are turned on, showing up as a white pixel in footage.
A stuck pixel is when one of the three sub pixels are turned on, so it can show up as red, green or blue.
You can also experience what could look like damaged pixels if the sensor is dusty or dirty. In that case, get your camera cleaned professionally. You can risk serious damage to the camera if you’re swabbing the sensor when shutter’s curtain or mirror closes. If you’re seeing out of focus areas, this may be caused by a dirty lens.
Here’s an eHow video on dead pixels.
There are a lot of methods that will work in a lot of host applications. There are tools out there that you wouldn’t consider to do the job but will actually take care of damaged pixels with ease.
First, Ryan Koo talks about how to fix damaged pixels in After Effects with the Clone Stamp tool. Read the tutorial
CC Wire Removal Tool
Wire removal tools are a great way to deal with damaged pixels. The purpose of wire removal tools is to remove wires or fishing lines on actors or props in your visual effects shot. Mark each end of the wire, then the wire removal tool will blend the adjacent pixels to cover the wire. You of course may need to track the wire if it’s moving, but wire removal is pretty straight forward. Read The Art of Wire Removal from FxGuide for more on wire removal.

RiverCityGraphix shows you how stuck pixels are fixed in AE with his method.
There are several other wire removal plug-ins on the market that may work just as well for fixing damaged pixels, like Boris Continuum Complete BCC Wire Remover. If you have another give it a try.
This Final Cut Pro effect preset was created to remove unwanted pixels from either “locked-off” shots or stills. Brendan Gibbons, the creator says, “The idea behind it was a simple way to help remove dead pixels, but you could also use it as a “digital concealer” to remove spots or blemishes etc.”
There are also lots of plug-ins out there made specifically for fixing damaged pixels, and others meant for bigger jobs but will do the trick quite well. Here are a few that you may already own.
BCC Pixel Fixer is made especially for this problem. Place a cross-hair over the bad pixel. BCC Pixel Fixer takes care of it. I demoed this plug-in at NAB and it’s very easy to use and works fantastically well. It is also great for removing dust and dirt from the frame.

RE:Fill is made for repairing holes and scratches. A tiny pixel is not too small of a job for RE:Fill. The description says, “selecting the nearest “good” pixel, mirroring pixels about a hole’s edge, or cloning from another ‘good’ region… and the good region can even come from another point in time or from another sequence altogether.”
There seems to be a lack of RE:Fill tutorials online, but it comes with a manual.

Note: If you’re a software developer and you’d like me to add your product to this list, email michele[at]toolfarm[dot]com with information on how your plug-in can do the job. A link to a video tutorial on the subject would be very helpful. It’s nothing personal if you were not included on the list!
If you’re having this issue with your own gear, this is worth a try. They don’t give instructions on the video, but just point your camera at this and record for 10 minutes. I haven’t tried it myself so I can’t guarantee anything, but it’s supposed to work. Warning, this one is seizure inducing!
