hello,
i get some highlight dots in my raw video when shooting with high iso (12800).
1. convert my mlv file with mlv_dump to dng files. Open first file and it looks good in PS camera raw. Original dng file here
2. import dng files in Davinci Resolve and get some highlight dots. My project settings is Cinema DNG  with BMD Film and "highlight recovery" checkbox enabled
3. After export from DR to MOV file highlighs dots keeps. Screenshot from MPC-HC

MOV file for example

I try use --fixcp and --cs2x2 but nothing changes. How to fix ?

It's a common issue for all canon cameras shooting RAW. Some have more, some have less dead-hot pixels. In RAW mode you shouldn't really go over 3200 or even 1600 ISO.
6D - 5D - NEX - M50!

What could help a little is remapping hot/dead pixels.
google for canon pixel remapping body cap.

Ok, i`m understand my mistake. But what can i do to fix in exist mlv file ?

I through that hot\dead pixels are stable on matrix. But on video they are chaotic moves during all file.

@sterid
You can try my app to convert mlv/raw files.
It has Hot/dead pixel remover.
MLVProducer. p.s. sorry for my bad english.

thax, your function "remove hot px" work fine.
But I just change my workflow to use Adobe Camera Raw before import in Resolve. ACR has built-in function "remove hot pixels".

sterid

Unfortunately ACR didn`t remove hot pixel in file. ACR just don`t show hot pixels....

I find this function in different tool - MlRawViewer (Just press 0 and add to export queue). Great!
