Producing and viewing video-based group conversations

A system for producing a video-based group conversation for transmission over a social networking platform, said system comprising:

• a server comprising a processor configured to execute instructions;
• a memory coupled to the server and comprising stored instructions that are executable by the processor to cause the server to:
• receive a request from a first user at a first mobile device to create a video-based group conversation accessible to a plurality of members of a social networking platform, wherein each member who joins the video-based group conversation is at least one of a video-feed-receiving member or a video-feed-contributing member, where the video-feed-receiving member is a member who has permission to view a video feed of the video-based group conversation but not to contribute to the video feed and where the video-feed-contributing member has permission to view the video feed and to contribute to the video feed;
• prior to the video-based group conversation transpiring, display, in a user interface of the first mobile device, a countdown indicator that indicates when the video-based group conversation is to start, wherein the user interface further includes a start element that triggers the start of the video-based group conversation as counted down by the countdown indicator, and wherein the start element is displayed simultaneously with one or more thumb-nail sized images corresponding to one or more of the members of the social networking platform;
• in response to the video-based conversation transpiring, present, on the user interface, a first video signal associated with the video-based group conversation in conjunction with:
• i) a first user interface element for controlling transmission of the first video signal,
• ii) a second user interface element that, when selected by the first user, triggers an invitation to be sent to a second user device of a second user, wherein the second user is initially determined to be a video-feed-receiving member, wherein the invitation invites the second user to become a video-feed-contributing member, resulting in the second user being able to contribute to the video feed by participating on-screen in the video-based group conversation, and wherein, in response to an acceptance of the invitation by the second user, the second user is caused to transition from being the video-feed-receiving member to being the video-feed-contributing member and is permitted to contribute to the video feed, and
• iii) a third user interface element is selectable by the first user to subsequently control participation of the second user;
• receive the first video signal from the first mobile device;
• and
• stream the first video signal to respective mobile devices of the plurality of members of the social networking platform who join the video-based group conversation for simultaneous presentation thereto.
