Hello there!

I got the a7s for like 7 months now. And since day 1 I am struggling with noisy footage. After researching about different PP settings, exposures, grading. I still getting noise (also in daylight), even in my mid-tones. So some people advised me to go to the shop. So I went to the shop. And I told them about this problem.

 

He asked which ISO I do shoot. I said between 800 - 1600/3200. And he answered that I have to shoot at 3200 for best quality. (I already did a lot of shots with 3200, but I thought that I give it 1 more try). But still had noisy footage. So I did this simple test with scopes from premiere. And what I see in my scopes is that in my mid-tones and shadows I see dancing pixels.(watch 0:25)

 

You can see moving pixels in the black background, on the LED light controller (in the colored buttons, and the grey part) and also in the green parts of the mini cactus.

I use a7s + 55mm 1.8 Zeiss. (+ Sony SDXC card 128gb 94mb/s)

 

You guys are my last hope. 

I hope I have explained clear enough to understand for you guys.

Surely as the ISO increases, so does noise?

No that not how a a7S works.

Your Chocomel C0264 looks like it's covered in lint... GREEN lint of the fuzzy variety. Mucked with a bit of the image and it's clear to me something's in there.
