Bad Bars of noise in my raw video //// banding issues.[5D3]
« on: March 21, 2014, 01:42:23 PM »
Just thought I'd put it out there... Why am I getting such bad banding...

Is it just my camera orr whats the deal.. Evident black noise bands consistently down my camera.

Camera info? ML nightly version info? Resolution info? Crop non-crop info?

I am using in camera iso controls,

Nightly version V2.3NEXT.2014Jan17.5D3113

just shooting at 1920 1080 and no crop. Just 1x. I shot a bunch of footage all weekend and same result. hmm I dont see this in anyone elses footage.

So i am thinking maybe its the fact I am not using the magic lantern ISO, I thought the issues with using mulitples of 160 in ISO was fixed with the 5dmkIII and was only a 5dmkII issue. maybe I am wrong? :)

It's the same pattern noise as reducing the gains to much with iso_research tools.

If raw2dng doesn't fix it, upload a sample (a DNG frame should be enough).
