Hi Samuel - it would be helpful if you added screenshots of your Blender render and project settings, and your DaVinci Resolve export & project settings

# Weird (interlacing?) artifacts in my rendered video

(Asked by: username_0 on 2020-12-06)

I've been making a YouTube outro for my channel with blender recently.

I exported the outro in blender using the QuickTime container together with the QT / QT Animation video codec at 60fps. Everything worked just fine until I tried to put the outro after a test video using Davinci Resolve 17. The test video I exported with Davinci at 30fps using the mp4 format and h.254 codec had weird line artifacts. I did a bit of googling and discovered that my problem could have something to do with a thing called interlacing.
I think it might be caused by the process that's "scaling down" a 60fps video to 30fps... But I am completely unsure how I can solve this problem...

Any suggestions?
