Red artifacts in footage

PostThu Jul 27, 2017 5:28 am

When importing raw footage to Davinci I get weird red dots and lines on the footage. They don't show up on when playing it back on the camera's monitor. Only when playing them on Davinci, these artifacts get baked into the export too.

:x :x :x :x

This was a paid shoot and I'm very worried that there might not be a solution to it.

Davinci Studio 14.6
Ursa Mini 4k EF

Pleas Help!

Specs

OS Sierra 10.12.5
8gb ram
Intel iris pro 1536 mb
i5 2.7ghz

using Davinci Studio 14.6 Beta

UPDATE:

I deleted Davinci 14.6 beta and reinstalled the current studio version and the problem was solved. No more artifacts, also exported the same clip and everything seemed fine.

It would still be helpful to have a frame to look at, so we can try to reproduce the issue and see what's causing it.

Do you see the artifacts in stop, or only when the clip is playing?

Here is the original dng file:

They were barely visible in stop but very noticeable while playing.
