1. A method comprising:

receiving, by a computing system, a video stream that includes multiple frames captured by a physical camera;

identifying, by the computing system and in a current frame of the multiple frames of the video stream, a location of a feature of an object that is depicted in the current frame;

determining, by the computing system, a stabilized location of the feature in the current frame by:

determining a potential stabilized location of the feature in the current frame and the identified location of the feature,

determining a second distance between the potential stabilized location of the feature and a previously determined location of the feature, and

wherein the determining of the stabilized location of the feature comprises determining a weighted average of the first distance and the second distance, subject to the first distance being within a cropped range of the video stream; and

generating, by the computing system, a stabilized view of the current frame using the stabilized location of the feature.
