Looks like interlacing artifacts to me.
Assuming you want / need progressive output, there are a couple of things you can do when using interlaced source material:
1) Make sure your project is set to progressive.
To do this, select the project in the browser. The upper portion of the inspector’s Information pane will show your frame size and frame rate, audio configuration, and color space settings. You’ll also see a “Modify” button – that’s what we’re after. You can change frame size, codec, starting timecode, audio configuration, and switch between interlaced and progressive. Keep in mind that you can’t change frame rate once you have media on the timeline.
2) Make sure your media is set to deinterlace.
Select the clips you want (in the browser or timeline), and in the inspector’s Information pane, select ‘Settings’ from the pop-up menu at the bottom of the pane. Once there, you’ll find the ‘Deinterlace’ checkbox.
Ideally, you’d set this prior to edit so that you only have to do it once in the browser. Any clips edited into the timeline prior to making this change will also need to be changed.
