摘要： 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.

摘要： Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method for performing post-production editing includes receiving one or more footages of an event from at least one user. The method includes constructing, based on information about the event, a script to indicate a structure of multiple temporal units of the one or more footages, and extracting semantic meaning from the one or more footages based on a multimodal analysis comprising at least an audio analysis and a video analysis. The method also includes adding editing instructions to the script based on the structure of the multiple temporal units and the semantic meaning extracted from the one or more footages and performing editing operations based on the editing instructions to generate an edited multimedia content based on the one or more footages.

摘要： A computer implemented method for setting a playback speed of media content comprising audio, the media content having a defined normal playback speed, the method comprising: receiving an indication that the media content is to be played at a speed different from the normal playback speed of the media content, analysing the audio for determining a type of audio; and determining a playback speed different from the normal playback speed depending on the determined type of audio, and setting the playback speed of the media content to the determined playback speed.

摘要： Presented herein are method and systems for generating a mood based summary video for a full-length movie, comprising receiving a full-length movie, receiving a Knowledge Graph (KG) annotated model of the full-length movie generated by annotating features extracted for the full-length movie, segmenting the full-length movie to a plurality of mood based time intervals each expressing a certain dominant mood based on an analysis of the KG, computing a score for each of the plurality of mood based time intervals according to one or more of a plurality of metrics expressing a relevance level of the respective mood based time interval to a narrative of the full-length movie, generating a mood based summary video by concatenating a subset of the plurality of mood based time intervals having a score exceeding a predefined threshold; and outputting the mood based summary video for presentation to one or more users.

摘要： Systems and methods are described herein for displaying subjects of a portion of content. Media data of content is analyzed during playback, and a number of audio signatures and/or action signatures are identified. Each signature is associated with a particular subject within the content. The audio signatures are stored, along with a timestamp corresponding to a playback position at which each signature begins, in association with an identifier of the particular subject. Upon receiving a command, icons representing each of a number of signatures at or near the current playback position are displayed. Upon receiving user selection of an icon corresponding to a particular signature, a portion of the content corresponding to the signature is played back.

摘要： Techniques are described for assisted creation of video rules via scene analysis. In some implementations, a scene is obtained, a shape of an element in a ground plane shown in the images of the scene is identified, user input that defines a shape of a region of interest used in a video rule is obtained, that the shape of the region satisfies a reshape criteria based on the shape of the element in the ground plane shown in the images of the scene is determined, and a reshaped region based on the shape of the element in the ground plane shown in the images of the scene is determined.

摘要： Methods of creating one or more audio objects to accompany a sequence of multimedia objects are disclosed. According to one embodiment, the method includes using a processor to analyze the multimedia objects and corresponding recorded metadata to generate derived metadata. The method further receives a selection of one or more analysis tools that are configured to analyze the recorded and derived metadata. Next, a selected subset of multimedia objects are identified and sequenced, which will ultimately be coupled to and accompanied by one or more audio objects. Lastly, an embodiment of the present invention generates an audio track to accompany the selected subset of multimedia objects.
