Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for encoding video data. Various aspects may include identifying keyframes in a source video. Aspects may also include mapping differences between keyframes and consecutive frames in the source video into blocks. Aspects may also include generating an image including the blocks. Aspects may also include storing coordinates of the blocks in the image and corresponding source video information as metadata. Aspects may include compressing the image, the first keyframe, and the metadata into a single compressed file. Aspects may include reconstructing the source video for playback based on the image, keyframes, and metadata in the compressed file.

Abstract: A presentation service generates an audience interface for an electronic presentation. The audience interface may simulate an in-person presentation, including features such as a central presenter and seat locations for audience members. The audience members may select emotes which may be displayed in the audience interface. The emotes may indicate the audience members' opinion of the content being presented. The presentation service may enable chats between multiple audience members, grouping of audience members private rooms, and other virtual simulations of functions corresponding to in-person presentations.

Abstract: A system that enables synchronized interaction between voice input and a visual user interface is described. The system receives, by a network site via a first user interaction channel, a user request to perform an action with a listing network platform. The system establishes, by the network site, a session associated with a session identifier for the user request and provides an option for the user to continue interacting with the listing network platform through a second user interaction channel. The system, in response to receiving input that selects the option, uses the session identifier associated with the session to synchronize a first set of inputs received through the first user interaction channel with a second set of inputs received through the second user interaction channel to complete the action on the listing network platform.
