In a video system for imaging a target object by using first and second imaging devices, an information processing method is executed by the first imaging device. The information processing method includes: a step for acquiring a first elapsed time indicating the time elapsed after start of recording by the first imaging device; a step for requesting the second imaging device to transmit a second elapsed time indicating the time elapsed after start of recording by the second imaging device, and receiving the second elapsed time; a step for acquiring a required time to receive the second elapsed time after the request is made; and a step for, based on the first elapsed time, the second elapsed time, and the required time, calculating an offset time for synchronizing a first moving image recorded by the first imaging device and a second moving image recorded by the second imaging device.

The disclosed technology provides solutions for enhancing a user's experience of music video playback. Beat temporal locations are identified in the soundtrack of a multimedia content item, and surround the beat temporal locations, the playback speed of video frames is adjusted. An audio event trigger is determined using a beat decomposition process that generates event vectors including time-index information, wherein the event vectors indicate temporal locations of the audio event trigger. Playback speed can be changed by advancing the timing of displayed frames before the occurrence of a rhythm event, and by delaying it after. Shader parameter courses can be changed by being accelerated before the occurrence of a rhythm event and by being decelerated after.

In general, user interfaces for controlling a plurality of multimedia players in groups are disclosed. According to one aspect of the present invention, a user interface is provided to allow a user to group some of the players according to a theme or scene, where each of the players is located in a zone. When the scene is activated, the players in the scene react in a synchronized manner. For example, the players in the scene are all caused to play a multimedia source or music in a playlist, wherein the multimedia source may be located anywhere on a network. The user interface is further configured to illustrate graphically a size of a group, the larger the group appears relatively, the more plays there are in the group.

Embodiments of the present application provide a video recording method and device. The method includes: receiving, by an application of a mobile terminal, a video recording instruction of a user; generating, according to a photographing scene, a video stream that can be edited according to segments, the video stream including at least one frame sequence segment; and uploading the edited video stream to a server. According to the present application, by generating a video stream consisting of at least one frame sequence segment during video recording, where the generated video stream can be edited according to segments, the error tolerance of video capture is improved, and the costs of later video editing are reduced.

In one aspect, an example method includes (i) receiving a first group of video content items; (ii) identifying from among the first group of video content items, a second group of video content items having a threshold extent of similarity with each other; (iii) determining a quality score for each video content item of the second group; (iv) identifying from among the second group of video content items, a third group of video content items each having a quality score that exceeds a quality score threshold; and (v) based on the identifying of the third group, transmitting at least a portion of at least one video content item of the identified third group to a digital video-effect (DVE) system, wherein the system is configured for using the at least the portion of the at least one video content item of the identified third group to generate a video content item.

Systems, methods, and software described herein manage the playback speed of video data based on processing objects in the video data. In one example, a video processing service obtains video data from a video source and identifies objects of interest in the video data. The video processing service further determines complexity in frames of the video data related to the objects of interest and updates playback speeds for segments of the video data based on the complexity of the frames.

A method for generating a slow motion video. The method includes segmenting, by an electronic device, objects in the video. Further, the method includes determining, by the electronic device, an interaction between the segmented objects. Further, the method includes clustering, by the electronic device, the segmented objects in the video to generate object clusters based on the interaction. Further, the method includes determining, by the electronic device, a degree of slow motion effect to be applied to each of the object clusters in the video based on a significance score of each of the object clusters. Further, the method includes generating, by the electronic device, the slow motion video by applying the degree of slow motion effect to that has been determined to corresponding the object clusters.

Embodiments of the invention are related to a system and method of controlling a display of an image stream. The system may include a memory to store the image stream; the image stream may comprise a plurality of image frames. The system may further include a processor configured to execute the method. The moving image stream may be displayed to a user in an image stream display area of a screen and a frame rate control interface may be generated on a speed control area of the screen, such that the image stream display area is horizontally adjacent to the speed control area. An indication of a desired frame rate for displaying the image stream of the image frames may be received from the user, in that the frame rate may be selected according to a location of a pointing indicator in the speed control area.

An information processing device performs control to record identification information of at least a part of a plurality of magnetic tapes belonging to a magnetic tape pool, on the plurality of magnetic tapes or on a recording medium except for the magnetic tapes that is provided in a plurality of magnetic tape cartridges including the plurality of magnetic tapes, respectively.
