Best and easiest way to remove tracking markers from green screen video
You can do this quite easily without content-aware fill or anything like it. I'd tackle this by doing the following:

create a rough shape for each tracking-point (the color doesn't matter)
track each point using the native after-effects tracker and apply the track to the corresponding shape.
All the shapes should now stick to their tracked point. Precompose all the shapes.
Under &quot;track-mattes&quot; you can now select your shape-precomp as &quot;invered alpha-matte&quot;. This cuts out the opaque areas of the shapes, effectively removing the tracking-points.
Key your footage.

I hope this helped you, have a nice day!
