ACR should have a little bit of color noise correction by default.  hot pixel is not a problem.

What do you mean by: "hot pixel is not a problem" ... For me that´s a problem

you can use pencil correction on ACR. so there's no problem.

Thanks - works fine!

Btw: From where are these green dots? this is new in raw - i´ve never seen them on the h264 recordings...

Maybe this will help:

Step 1 Detach the lens from your Canon camera and use the cap

Step 2 Turn your camera on. Go to the menu and select "Sensor cleaning" under the utilities menu.

Step 3 Turn the dial to select "Clean manually" under the sensor cleaning option.

Step 4 Turn the dial to select "OK" and then press the "Set" button. The mirror will lock up and the shutter will open. Allow the shutter to remain open for at least 30 seconds.

Step 5 Turn your camera off and reattach the lens. Take a few test shots to see if the problem has been corrected. In most cases the red or white pixel will no longer be a problem because your camera has been remapped

If it does not help the first time, then change the ISO settings and try again.

I read some where you have to disable ML? or the bootflag

Is it possible to do it with ML enabled or best to turn off whilst doing remapping?

Its working with ML too. Or simply remove your card..
