Lot's of thread to remove hot spots out there. Try google raw hot spots + Magic Lantern
In my case:
- First, during the take: I tried not to work with high ISO for a lot of time. That cause some pixels with problems.
- Auto clean - only the camera do this, not your hands - dust.
- I use to put in the conversors "stripe corrections". I have the hope that this help...
- In DaVinci Resolve, if I have dead pixel, I place a "transparent mask" and apply in each spot some blur, in youtube are a couple of videos. Maybe you have always in the same place and you can save your mask and apply when is a big problem for you.
Hope this help you.
