Hi hjfilmspeed, AFAIK, when a camera gets hot, and it does if the sensor is dumping images continuously, the heat causes sensels to get "hot" or act in strange ways, the same way heat debilitates everything. The BMPCC camera, by the way, goes through batteries because it uses powered Peltier cooling on the sensor--or so I've heard. In short, there's a good chance you're going to get hot pixels if you keep the camera on, shooting video. The bigger question is can you be certain, even if you have a hot pixel list, that more pixels won't get hot as the camera continues shooting?
In normal video, the hot pixels are mostly smoothed out, but in astronomy, if that's what you're doing, it's not so simple.
You can just open a DNG in Photivo (for example), load the image at 1:1 in "unbayered" mode, get the position of each "dead/hot" pixel, and feed it into any DNG to TIFF conversion routines through a badpixellist.txt file where each pixel is in x,y, time (you can just put 0) coordinates.
Anyway, if there is a concrete need to create some sort of fix, let's talk, otherwise, let's just keep it on the list of things to do?
