Title: FPS Override - massive "dead/hot" pixels
Post by: 350D on May 23, 2015, 07:18:21 AM
Check this video first:


on the second half of the video (night time) you can check for hot/bright pixel overlay.
What is that and how to get rid of that?
I'm using latest build for 6D and FPS override setup with low light value.
I've checked this one year old topic (http://magiclantern.fm/forum/index.php?topic=6927) already with no luck...

It's not dual iso, dual iso can cause horizontal lines, not random dots.

It's weird, looks like it grows over time, and the white dots are very static, they don't move.
Is it also visible in the DNG's ?

@Licaon_Kter here is no workflow, movie recorded directly in camera using FPS override function.
@Levas no DNG available, this is a mov file from camera

Ah, looks like the fps override screwed up some stuff.
Looks like the canon in camera software is doing something with the dead pixelmask.
Only timing looks really bad...
What framerate did you use for fps override?
I remember reading somewhere that 1fps more or less can make a difference with fps override.

That was 1 or 3 fps settings, what you can recommend for 6D?

I have never used fps override for normal mov files, so I can't recommend any setting, just trial and error.
I shoot timelapse with raw photo's and the build in timer from magic lantern.
