<p>The tracker is designed to track whatever you put inside the tracker's window.  It doesn't matter whether you want to track something in the middle of your frame or on the edge.  All that matters to the tracker is that it can "see" enough detail of whatever it's being told to track that it can lock on it in the various dimensions it can track: pan, tilt, rotate, zoom, and 3d perspective.</p>

<p>Your background looks really tricky to track because it's very low contrast (relatively speaking).  You could dramatically boost the contrast of your background, for the purpose of building a good track, then use that tracker data on the non-contrast-enhanced image.  Just use a square or a circle over a small but distinct area you want to track and it should be good.</p>

<p>I am completely new both to video editing and DaVinci Resolve 14.</p>

<p>I would like to apply stabilization to a clip which has a constantly moving and changing object in the middle. Therefore I only want to track points which are <em>outside</em> of a certain region in the middle of the screen.  Is it possible to mark the middle region by drawing a power window and then track everything that is <em>outside</em> of it?</p>

<p>So far I have been trying to manually draw an "inverse window" which selects mostly everything except the middle.  Is this the right way to go about it?</p>

# DaVinci Resolve: Track with points outside of a window

(Asked by: username_0 on 2017-09-13)

I am completely new both to video editing and DaVinci Resolve 14.

I would like to apply stabilization to a clip which has a constantly moving and changing object in the middle. Therefore I only want to track points which are *outside* of a certain region in the middle of the screen. Is it possible to mark the middle region by drawing a power window and then track everything that is *outside* of it?

So far I have been trying to manually draw an "inverse window" which selects mostly everything except the middle. Is this the right way to go about it?
