In the present disclosure, a collaborative workspace fosters content creation between users in a synchronous and/or asynchronous manner by enabling automatic generation and management of collaborative media objects that automatically combine content from a plurality of users into a single media object. This is extremely beneficial in technical scenarios where users are creating projects, assignments, presentations, etc., by removing the need for users to manually stitch together and combine content to create a final product. For example, the collaborative workspace is adapted for a video discussion application/service, where users create one or more video clips (e.g., video feeds, live video feeds) in response to a posted topic. In at least one instance, a collaborative workspace for a video discussion application/service may be integrated to display within another type of application/service. However, the present disclosure is extensible to work with any type of application/service and any content type.

A method for generating a cyclic video sequence (SC), implemented by a data-processor (11). The method includes receiving a video sequence (S); determining a first singular point (P1) of the video sequence (S) in a first interval (11) of the sequence (S) and a second singular point (P2) of the video sequence (S) in a second interval (12) of the sequence (S). The first and second singular points (P1, P2) have a maximum similarity according to a given similarity criterion; then generating a connecting sequence (SR) between the image of the video sequence (S) corresponding to the second singular point (P2) and the image of the video sequence (S) corresponding to the first singular point (P1) by morphing then constructing the cyclic video sequence (SC) by concatenation of a fragment (S′) of the video sequence (S) extending from the first singular point (P1) to the second singular point (P2), and of the connecting sequence (SR).

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and method for setting ad breakpoints in a video. The program and method provide for accessing a video; determining plural shot boundaries for the video, each shot boundary defining a shot corresponding to a contiguous sequence of video frames that is free of cuts or transitions; and for each shot boundary of the plural shot boundaries, performing a set of breakpoint tests on the shot boundary, each breakpoint test configured to return a respective score indicating whether the shot boundary corresponds to a breakpoint for potential insertion of an ad during playback of the video, calculating a combined score for the shot boundary based on combining the each of the respective scores, and setting, in a case where the combined score meets a threshold value, the shot boundary as the breakpoint.

In implementations of determining video cuts in video clips, a video cut detection system can receive a video clip that includes a sequence of digital video frames that depict one or more scenes. The video cut detection system can determine scene characteristics for the digital video frames. The video cut detection system can determine, from the scene characteristics, a probability of a video cut between two adjacent digital video frames having a boundary between the two adjacent digital video frames that is centered in the sequence of digital video frames. The video cut detection system can then compare the probability of the video cut to a cut threshold to determine whether the video cut exists between the two adjacent digital video frames.
