Looks like an interlacing issue.
Either you’ve got progressive footage in an interlaced timeline, or interlaced footage in a progressive timeline.
If your project is progressive, select that first shot and go to the ‘Info’ tab of the inspector, Settings view, and tick the Deinterlace checkbox. That should clean it up – verify that setting for each clip in the timeline.
If your project is interlaced, you’ll want to change it to progressive (changing the project frame rate only works on an empty timeline, however you can switch from Interlaced to Progressive with an existing edit) and then make sure that all of your interlaced shots have that Deinterlace setting active. You can change it in the browser before you start an edit, just be aware that changing the setting on the master clip in the browser won’t affect the bits that are already in a sequence. Anything after that will be groovy.
