A method, computer system, and a computer program product for generating a summary video from a plurality of presentation attendee notes is provided. Embodiments of the disclosure may include collecting the plurality of attendee notes from a plurality of attendees of a presentation and then analyzing the collected plurality of notes to identify a plurality of common note topics. The identified plurality of common note topics may be correlated to a plurality of portions in a presentation video of the presentation which is used to generate the summary video by combining the correlated plurality of portions in the presentation video.

A cartridge management system that manages a plurality of cartridges, in each of which a magnetic tape is housed, includes a processor, and a memory incorporated in or connected to the processor, in which the processor is configured to execute data rewrite-in processing of rewriting data stored in the magnetic tape, in a specific cartridge among the plurality of cartridges based on an access frequency indicating a frequency of access to the data, and cartridge replacement processing of replacing the data stored in the magnetic tape of the specific cartridge and the data stored in the magnetic tape of another cartridge among the plurality of cartridges.

Embodiments of the invention are related to a system and method of controlling a display of 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.

The present disclosure is directed toward systems and methods for ranking media effects. For example, systems and methods described herein enable a user to select and apply one or more media effects to a media communication such as a digital photograph or video. Systems and methods described herein identify and rank media effects based on characteristics associated with the user and the user's client-computing device. Furthermore, systems and methods described herein automatically present the top-ranked media effects to the user such that the user can easily select and apply one or more media effects that are tailored specifically to the user.

A method, computer system, and a computer program product for content navigation within a media player is provided. The present invention may include displaying, by a computing device, a media content and a corresponding textual content. The present invention may include receiving, from a user, input regarding the textual content. The present invention may include modifying a playback of the media content based upon the input regarding the textual content to generate a modified media content. The present invention may include playing the modified media content.

An example system may provide a graphical user interface displaying a timeline graphical element, where the timeline graphical element represents a timeline of a media clip, and a graphical current point indicator indicating a selected point on the timeline. The system may provide a marking graphical element that is selectable to record a start point or an end point of a segment of the certain media clip. The system may receive a first user input scrubbing the timeline graphical element horizontally, and it may receive a second user input indicating a user interaction with the marking graphical element. The system may determine a start point and an end point of each of a plurality of segments of the timeline graphical element corresponding to the certain media clip based on the second user input and update the graphical user interface based on the determination.

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.

This disclosure describes one or more implementations of systems, non-transitory computer-readable media, and methods that generate a temporally remapped video that satisfies a desired target duration while preserving natural video dynamics. In certain instances, the disclosed systems utilize a playback speed prediction machine-learning model that recognizes and localizes temporally varying changes in video playback speed to re-time a digital video with varying frame-change speeds. For instance, to re-time the digital video, the disclosed systems utilize the playback speed prediction machine-learning model to infer the slowness of individual video frames. Subsequently, in certain embodiments, the disclosed systems determine, from frames of a digital video, a temporal frame sub-sampling that is consistent with the slowness predictions and fit within a target video duration. In certain implementations, the disclosed systems utilize the temporal frame sub-sampling to generate a speed varying digital video that preserves natural video dynamics while fitting the target video duration.

The present disclosure relates to systems and methods video recording and video replaying. The method may include obtaining video data from a video recording device. The method may also include generating an index item corresponding to the video data if the video data includes a key frame, wherein the index item includes an index position of the video recording device corresponding to the key frame, and an offset address used to determine an address where the key frame is stored. The method may further include storing an index table including at least the index item in a video.
