This is a highlighter that is useful in many circumstances. I initially designed this one to be used in sports videos, highlighting a specific player. ScoutNationHD, a well-known YouTube channel that showcases players, uses this highlighter. Check out this video to see it in action.
The file includes 2 versions: one has a light blue fill, while the other has no fill.
Note that this is a PNG sequence that can be imported straight into your project.
