摘要： This disclosure describes methods and systems for improving quality in video production. A video production device receives inputs from a user for only a subset of image frames presented for use in producing a video. Each of the inputs indicates a point of interest (POI) in a corresponding image frame, indicative of a region of interest for inclusion as a scene in the video. A video processor evaluates a spatial path of the indicated POIs relative to a bounding scene of interest (BSI), which represents an extent of a field of view of a corresponding camera, and dynamically adjusts the field of view to steer subsequently acquired image frames to be within the BSI. The video processor produces the video with all scenes arranged successively at a periodic interval. Use of the spatial path for scene or camera-viewpoint selection is designed to optimize quality of the produced video.

摘要： This disclosure describes methods and systems for managing video frame rate at a video production site. A video processor of a first video production site may process received video frames received via a network with dynamic transmission properties. A frame rate controller may monitor at an output buffer of the site, an average rate of processed video frames received from the video processor, and may detect that the average rate of processed video frames received from the video processor has decreased to a level below a predefined output frame rate for transmitting processed video frames to a third video production site. The frame rate controller may increase a rate of video frames being provided to the video processor, to a level above the predefined output frame rate to restore the average rate of processed video frames received from the video processor, to the predefined output frame rate.

摘要： This disclosure describes methods and systems for integrating video production over a network of video production sites. The video production sites may each provide a video production function as part of a distributed video production process across the network. An integration server may receive production quality metrics from at least a first video production site and a second video production site. Each production quality metric may be indicative of quality of a corresponding sequence of video frames produced at a corresponding video production site. The video production integration server may dynamically control selection or merging of video frames from the first and second video production sites to generate an integrated video production, by comparing production quality metrics received from the first and second video production sites that correspond to a same sequence of video frames, against a threshold value or against each other.

摘要： This disclosure describes methods and systems for managing video frame rate at a video production site. A video editing processor at one of a plurality of video production sites may monitor an instantaneous rate of video frames processed by a user, and may determine an average rate of video frames processed by the user based on instantaneous rates monitored over time. The video editing processor may detect that the average rate has dropped below a predefined output rate. A controller may determine a rate of change of an instantaneous input rate of video frames being presented to the user for processing, and may increase the input rate of video frames being presented to the user, over a period of time such that the rate of change of the instantaneous input rate is below a predetermined threshold, to restore the average rate to the predefined output rate.
