Fine red horizontal lines through media

PostFri Feb 05, 2021 5:34 pm

I'm testing out the latest beta and I'm seeing fine red lines through all of my media. RED, prores, doesn't matter. MacOS 11.2. Exports from this footage have odd strobing in some of the tones.

Do the exports also show the lines?

Yes, as I mentioned the exports also show strange strobing in certain warmer tones. Currently seeing these issues with ACES and DaVinci color managed workflows. Non color managed has no issues.

Alright.

I haven't seen anything similar with my own ProRes ACES projects in any version of Resolve for Windows.

Possibly it's a mac bug.

If this is a 'trash can' MacPro, it might be a faulty GPU.

Not a GPU issue as I just downgraded to 16 and catalina without issue. Probably an issue with eGPUs under Big Sur/DR17 as I have a Sonnet eGPU enabled via purgewrangler

Fyi, I eventually figured out it was Resolve's noise removal that was causing these lines. Delete that node, no more lines.
