Okay, I see the field banding. There are a few ways to fix it but I think the essayist is to de-interlace it. I know you said you already tried that. If you de-interlace the clip in Motion it throws the Tracker off. De-interlace the clip in FCP and then export it out as a new clip. This is called “baking”. That will solve the problem if the de-interlace filter gets rid of the field banding. Also, the shot looks great. Hope this helps.
