1. A method for automatically reframing a video conference participant in a video stream, the method comprising:
capturing video of the participant;
generating a pixel coordinate array for each respective frame of the video;
determining respective coordinates of a respective absolute center of each respective frame of the video;
detecting, within a first frame of the video, a first position of the participant within the pixel coordinate array;
calculating a participant center represented by participant center coordinates of an area of the pixel coordinate array of the first frame corresponding to the first position of the participant;
calculating an offset for the first position of the participant, wherein the offset is based at least in part on a difference between respective coordinates of a respective absolute center of the first frame and the participant center coordinates of the first frame;
modifying subsequent frames of the video based on the offset, wherein the subsequent frames are to be displayed after the first frame of the video; and
presenting the modified subsequent frames of the video of the participant.
