The Curious Case Of Stuck White Pixels

Ho Ho,

I´m a little concerend about a possible fault/bug in the BMCC. I recently found white stuck/dead pixels in BMCC footage. John Brawley made a comment on BMCuser about it, saying that the camera possibly doesn´t always map out stuck pixels (which are perfectly normal on a CMOS Sensor but need to be mapped out).

My latest find was in philip bloom´s documentary:

I just wanted to show it. Maybe BMD has overlooked the dead pixel mapping function is not working flawlessly.

John commented on another post of mine saying that the BMCC checks for dead pixels on startup. Just wondering how well it really works :/

Yep, the cam does that but there was a bug in the preproduction models causing this function to not work properly on startup every time. John said he sometimes switched the cam off and on again until the mapping function worked
