Horizontal lines in fusion edited footage

Hi, I'm using Da Vinci 15 to my full satisfaction but now I got stuck - I edited some clips in fusion tab (brightness, contrast, etc.) and after changes on the very place of selector in edit tab I always find horizontal lines on few frames. It's really annoying, because I have to turn all changes back and let the clip unedited... If I change position of the selector, position of errors changes... Any idea, please?

That's interlaced, it seems.

but how to get rid off it? And in the same time use Fusion edits?

What's your final delivery, progressive or interlaced?

You can de-interlace under "Clip Attributes".

Truly - I can't find any setting progressive / interlaced... in clip attr. (right click on clip) or in delivery setup..

You need the Studio version for the de-interlace option.

You can with the free version select field processing in Project Settings, master project settings.
