Abstract: A processing system of a mobile device may determine the device's predicted viewport, which defines a portion of a real world environment that is expected to be visible to the device's user at a future time. The processing system may determine a set of extended reality anchors that are present in the real world environment, where each anchor stores a digital object that, when rendered by the device and presented to the user simultaneously with the real world environment, creates extended reality media. The processing system may remove a first subset anchors from the set, where locations of anchors in the first subset fall outside a threshold distance from the predicted viewport. The removing results in a second subset of anchors remaining in the set. The processing system may download a digital object from a second device, where the digital object is stored by an anchor of the second subset.

Abstract: A processing system having at least one processor may establish a communication session between a first communication system of a first user and a second communication system of a second user, the communication session including first video content of a first physical environment of the first user and second video content of a second physical environment of the second user, determine a first visualization action for a first physical object in the first physical environment in accordance with a first configuration setting of the first user for the communication session, obtain the first video content from a first camera of the first communication system, detect the first physical object in the first video content, and perform the first visualization action to modify the first video content. The processing system may then transmit first visualization information including the first video content that is modified to the second communication system.

Abstract: Methods, computer-readable media, and apparatuses for composing a video in accordance with a user goal and an audience preference are described. For example, a processing system having at least one processor may obtain a plurality of video clips of a user, determine at least one goal of the user for a production of a video from the plurality of video clips, determine at least one audience preference of an audience, and compose the video comprising at least one video clip of the plurality of video clips of the user in accordance with the at least one goal of the user and the at least one audience preference. The processing system may then upload the video to a network-based publishing platform.
