I'm grading a feature shot on REDone 4K.
I'm grading into Davinci 10.1.2, in half resolution.
Sometimes lines and colour artefacts appears on the image, not only on scope or via UltraStudio 4K, but also on the GUI of Davinci, il looks like de debayering problem (I haven't Red Rocket). The only solution to solve the problem is to restart the computer... I haven't tested yet, but I think it could appear in the render also.
Maybe not enough gpu memory. What is your hw config and sequence settings? how many nodes?
Sonnet Echo Epxress III with Esata card, FirewireCard, SAS card.
I get much worse image than these. Usually though, simple restart of Resolve solves, but still embarrassing in front of clients.
This may interest you.. Robin.
I was rendering a job yesterday, but the last clip of a project would not render at all with "your GPU memory is full. try reducing nodes.." message. This didn't make sense at all since the clip had much less correction than other clips in the job. After failing to render the clip with lots of different approaches, I tried to click off "force full debayer.." option on Deliver page although I had "full debayer" option turned on on the camera raw tab of the config page. To my surprise, it just rendered.
I'm not sure what caused this, but it's worth a try if you are in a trouble.
Thank's for your feedback. On my side I always rendered with "force full debayer", the problem seems then to come from somewhere else. But yesterday I downloaded the last version 10.1.3 and I will re-render the feature today to test if the render problem is still there.
