Abstract: The various embodiments described herein include methods and systems for presenting interactive media items. In one aspect, a method includes publishing, by a server system, an interactive media item, the publishing comprising providing access for a playback of the interactive media item based on metadata for the interactive media item. The metadata is generated using information associated with the interactive media item and including a mapping of an effect parameter for a first effect of the one or more effects to a touch input gesture. Playback includes, in response to detecting a first user input gesture corresponding to the touch input gesture, applying the first effect to the presented interactive media item. The applying of the first effect includes determining the effect parameter according to one or more characteristics of the first user input gesture, based on the mapping of the effect parameter to the touch input gesture.

Abstract: The various embodiments described herein include methods and systems for generating interactive media items. In one aspect, a method is performed at a server system. The method includes providing access for playback of an interactive media item based on metadata generated using information associated with the interactive media item. The metadata includes information associating at least one parameter with the interactive media item. The interactive media item is generated based on one or more user inputs selecting one or more interactive effects for association with the interactive media item. The user input(s) cause the server system to make the one or more interactive effects available to a subsequent viewer during the playback of the interactive media item, such that the subsequent viewer is able to interact with video and/or audio of the interactive media item by controlling the at least one parameter during the playback.

Abstract: The various embodiments described herein include methods and systems for storage of media item metadata. In one aspect, a method is performed at a server system with one or more processors and memory. The method includes receiving, from a client device, metadata corresponding to a modified media item, where the modified media item is a modified version of a media item corresponding to a particular node in a family tree within a database of media items. The method further includes, in response to receiving the metadata corresponding to the modified media item, appending, to the family tree, a new leaf node that is linked to the particular node, where the new leaf node corresponds to the modified media item.

Abstract: The various implementations described herein include methods, devices, and systems for generating media items. In one aspect, a method is performed at a server system. The method includes: (1) receiving one or more audio files; (2) obtaining one or more audio characteristics for the audio files; (3) receiving a request to generate a media item using the audio files, the request including one or more criteria; and (4) in response to receiving the request, generating the media item, including: (a) identifying one or more visual media files based on the criteria and the audio characteristics; and (b) generating synchronization information; (5) storing the media item in the server system; and (6) enabling playback of the media item by sending a link for the stored media item to the client device.
