Tracking Power Windows: Tips and Tricks in DaVinci Resolve

What do you normally do if you arent moving keyframes to the grade on that tug car, in this scenario, if you dont use keyframes? Also, I occasionally run into situations where the tracker cant lock a good “track” for more than a few frames on items like sunglasses, car parts, or other reflective surface. How do you best handle those cases? Thought of keyframes but keyframing too close causes unnatural jitter, yet far away and they aren’t accurate enough. Would love to know how other handle this type of situation, especially when in tight timelines. Many thanks!!
