Abstract: Aspects of the present disclosure involve a system for filtering conversations. The system generates for display, by a messaging application, a plurality of shortcut options, each of the plurality of shortcut options comprising a respective filtering criterion. In response to receiving input that selects a given shortcut option of the plurality of shortcut options, the system retrieves the filtering criterion associated with the given shortcut option. The system searches a plurality of conversations to identify a subset of conversations that match the filtering criterion. The system generates for display together with the plurality of shortcut options, a plurality of representations of the identified subset of conversations in which one or more messages have been exchanged between a user and one or more friends of the user.

Abstract: Systems and methods provide for advanced video editing techniques using sampling patterns. In one example, a computing device can receive a selection of a clip of a video and a sampling pattern. The computing device can determine a respective number of frames to sample from the clip for each interval of time over a length of time for a new clip. For example, the computing device can determine a function corresponding the pattern that relates time and the number of frames to sample, a histogram corresponding to the pattern, or a definite integral corresponding to the pattern, among other approaches. The computing device can extract these numbers of frames from the clip and generate the new clip from the extracted frames. The computing device can present the new clip as a preview and send the new clip to other computing devices.

Abstract: Systems and methods for radial gesture navigation are provided. In example embodiments, user input data is received from a user device. The user input data indicates a continuous physical user interaction associated with a display screen of the user device. An initial point and a current point are detected from the user input data. A radius distance for a circle that includes the current point and is centered about the initial point is determined. An action is selected from among multiple actions based on the radius distance being within a particular range among successive ranges along a straight line that starts at the initial point and extends through the circle. Each range among the successive ranges corresponds to a particular action among the multiple actions. The selected action is performed in response to detecting a completion of the continuous physical user interaction.

Abstract: Methods and systems are disclosed for joining community subgroups on a messaging platform. The methods and systems perform operations comprising: receiving, from a client device, account information associated with a user; searching, by a server, a list of communities to identify an individual community that corresponds to the account information; selecting a subgroup of a plurality of subgroups associated with the individual community in response to identifying the individual community; storing, by the server, the account information in association with the individual community; and adding the user to the subgroup to enable the client device of the user to access information of the selected subgroup that is exclusively available to members of the subgroup.

Abstract: A sender holds a first platform account with an interaction system. The sender selects a content item to be shared with a recipient. In response to determining that a recipient identifier of the recipient is not linked to a platform account, an off-platform communication is transmitted to a second user device associated with the recipient identifier. The off-platform communication is in an electronic format supported by the second user device and contains a user-selectable registration link. In response to detecting establishment of a second platform account linked to the recipient identifier, the recipient is enabled to access the content item on the second user device via a user interface provided by an interaction application. A relationship between the first platform account and the second platform account is established within the interaction system.

Abstract: A content request is received from a user device of a viewing user of an interaction system. An interaction application executing at the user device presents a viewing user interface that includes a content zone and an interaction zone. A third-party content item is presented in the content zone. The interaction zone comprises a first interaction subzone located in a lower section of the viewing user interface, outside of the content zone. The first interaction subzone includes a user-selectable interaction element. The interaction zone further comprises a second interaction subzone positioned adjacent to the first interaction subzone in the lower section of the viewing user interface. The second interaction subzone is located inside of the content zone and includes a user-selectable context element. Responsive to detecting an interaction gesture directed at the interaction zone, the interaction application automatically transitions from a viewing state to an interaction state.

Abstract: Embodiments for communicating and displaying collections of image and video clip content with an opt-out interstitial are described. In one example embodiment, a device receives interface information about a group of content collections from a server computer system. When a user inputs a selection of a first content collection, the device displays images and video clips in a sequence defined by the content collection. Each piece of content is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device presents an opt-out interstitial. Additional content collections generated from content submitted by other client devices can be received from the server computer system, and are presented based on a response input, or a lack of response input, to the opt-out interstitial. Some embodiments include content collections generated by the server computer system, as well as advertising elements presented between content collections.

Abstract: First content data is presented within a preview interface. The preview interface is a user interface presented to a user prior to transmission of content data to third-party users. A plurality of modification indicia is presented within the preview interface. Each of the plurality of modification indicia is associated with a respective modification function. The plurality of modification indicia includes a combination indicium associated with a combination function. Responsive to detection of user selection of the combination indicium, the combination function is activated. The activating of the combination function comprises causing presentation of a combination interface enabling the user to access second content data and combine the first content data with the second content data to create combined content data.

Abstract: A third-party user input content item is presented. A content sharing function is invoked responsive to determining user selection of a content sharing graphical element. The content sharing function comprises presentation of a destination graphical element identifying a first content sharing destination. The first content sharing destination is locked. A combination graphical element is user-selectable to invoke a combination function. Responsive to determining user selection of the combination graphical element, the combination function is invoked to access a second user input content item and combine the third-party user input content item with the second user input content item to create a combined user input content item. The first content sharing destination is unlocked and the user is enabled to share the combined user input content item to the unlocked first content sharing destination.

Abstract: In some examples, a technique according to the present disclosure includes detecting a determinable interaction pattern of interactions by a first user, via a user system, with a content item communicated on an interaction system by a second user. The determinable interaction pattern may comprise multiple access actions with respect to the content item by the first user. Responsive to detecting the determinable interaction pattern, an action graphical user interface element, that is user selectable to enable the first user to perform an action related to the content item, is automatically activated.
