Getting a snow grain glitch over top of my Sony footage in editing and final exports

Report · Sep 30, 2022

Camera: Sony Alpha 1, XAVC HS 4K 24p 4:2:2 10 Bit

OS: Windows 10 Pro 64 Bit

GPU: MSI RTX3090

64GB RAM

Software: Adobe Premiere Pro Version 22.6.2 (Build 2)

I'm shooting on a Sony Alpha 1 and I've had this issue since last year. I was hoping it'd be fixed by now but it doesn't look like it is. Any idea what could be causing it? This effect does not appear on top of my DJI Osmo Pocket 2 4k footage. Support was not helpful, they got me to change my Preview File Format to be QuickTime so I did that but it didn't change the grain then they disconnected when I sent them this picture as an example. As you can imagine this makes the product unusable for me as-is so I'm thinking of paying for Davinci Resolve as an alternative software. Any ideas what could be causing this or how to fix?

As seen on footage in Premiere Pro:

Footage played back in VLC (no grain so it isn't on original footage):

Hey defaultgt2ryxss846j,

Welcome to the community, and sorry for the issue. I do see the snow grain that you're referring to. Do you have the most recent version of Nvidia Studio Drivers (not the Game Ready Drivers)? Could you go to Sequence > Sequence Settings and let us know what your working color space is set to? Also, go to Project Panel > Right-click on footage > Modify > Interpret Footage and let us know if the colorspace override is selected. Would it be possible for you to share a sample source file through a personal message for us to reproduce this issue on our end?

Thanks,

Ishan

Hi Ishan! Thanks for the reply.

I have NVIDIA Studio Driver Version: 517.40

Working color space on Sequence Settings is Rec. 709

Will share source file. My smart VFX friend thinks it's a problem with the Sony codec talking to the image renderer inside Premiere pipeline but he's not sure what. He recommended I transcode the footage in another format using a different app like VLC.

Also if I switch the Color Space Override on to Rec 709 it still does the same thing.
