The present disclosure relates to a method and a system for marking multimedia files with file-marks and manipulating multimedia file(s) with the help of file-marks. In an embodiment, the present disclosure provides a method to link searchable keywords and tags to each of the file-marks. Each user of the multimedia file can define an index of file-marks with associated keywords and tags. The user of the multimedia file is provided with an option to play highlights created by a chosen set of users. One or more actions are initiated at the time of file-marking, associating the keywords and tags with a file-mark or at the time of manipulating the file-marked multimedia file. It also provides a method for facilitating file-marking one or more media files by one or more external file-marking device(s). Further, disclosure presents methods to efficiently encode and decode a multimedia file with highlights.

The present disclosure provides a display method. The display method includes displaying a first image based on a first scene; detecting whether a first condition is satisfied; and displaying a second image based on the first condition being satisfied. The first image is an image corresponding to a first portion of the first scene, the second image includes a character image of a viewer and an image of a second portion of the first scene, and the first portion is different from the second portion.

In certain embodiments, training of a neural network or other prediction model may be facilitated via live stream concept association. In some embodiments, a live video stream may be loaded on a user interface for presentation to a user. A user selection related to a frame of the live video stream may be received via the user interface during the presentation of the live video stream on the user interface, where the user selection indicates a presence of a concept in the frame of the live video stream. In response to the user selection related to the frame, an association of at least a portion of the frame of the live video stream and the concept may be generated, and the neural network or other prediction model may be trained based on the association of at least the portion of the frame with the concept.

Video information may define spherical video content having a duration. Spherical video content may define visual content viewable from a point of view as a function of progress through the spherical video content. Path information may define a path selection for the spherical video content. Path selection may include movement of a viewing window within the spherical video content. The viewing window may define extents of the visual content viewable from the point of view as the function of progress through the spherical video content. Time lapse parameter information may define at least two of a time portion of the duration, an image sampling rate, and a time lapse speed effect. A time lapse video may be generated based on the video information, the path information, and the time lapse parameter information.

A data processing system is disclosed, including one or more processors, a memory, and a plurality of instructions stored in the memory and executable by the one or more processors. The instructions may be executed to convert an input video file to a commonly used video format, and compare a resultant file size to a threshold size. In response to the file size being greater than the threshold size, the instructions may be executed to reduce a video bit rate of the input video file, and produce a Portable Document Format file that includes contents of an input Portable Document File and in which the input video file is embedded.
