An object of one embodiment of the present disclosure is to provide a product with a high added value to a user by preventing an unnatural character string from being combined, combination of no character string, and the like in a case where there is no voice or almost no voice before or after an image selected from within a moving image. One embodiment of the present disclosure is an image processing apparatus including: a selection unit configured to select, from a moving image including a plurality of frames, a part of the moving image; an extraction unit configured to extract a voice during a predetermined time corresponding to the selected part in the moving image; and a combination unit configured to combine a character string based on a voice extracted by the extraction unit, with the part of the moving image selected by the selection unit.

In a method for selecting of a prerecorded media file for superimposing into a video, a video of a scene is displayed on a display device of a mobile electronic device. A location of the scene is determined. A prerecorded video file is selected based at least in part on the location. The prerecorded video file is superimposed over the video, such that the video is partially obscured by the prerecorded video file. The prerecorded video file is played while displaying the video, such that the prerecorded video file and a non-obscured portion of the video are rendered simultaneously.

The various implementations described herein include methods, devices, and systems for detecting motion and persons. In one aspect, a method is performed at a smart home system that includes a video camera, a server system, and a client device. The video camera captures video and audio, and wirelessly communicates, via the server system, the captured data to the client device. The server system: (1) receives and stores the captured data from the video camera; (2) determines whether an event has occurred, including detected motion; (3) in accordance with a determination that the event has occurred, identifies video and audio corresponding to the event; and (4) classifies the event. The client device receives information indicative of the identified events, displays a user interface for reviewing the video and audio stored by the remote server system, and displays the at least one classification for the event.

A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

Methods, systems, and media for generating a summarized video using frame rate modification are provided. In some embodiments, a method for editing a video is provided, the method comprising: receiving, using a hardware processor, a video file; identifying a plurality of frames at a playback frame rate from the video file; generating an edited video file by extracting a subset of the plurality of frames, wherein the extracted frames in the subset of the plurality of frames are separated by a predetermined length in the plurality of frames and wherein extracting the subset of the plurality frames modifies a frame rate of at least a portion of the video file to an effective frame rate; storing the edited video file; and presenting the edited video file at the playback frame rate.

Provided are a video processing method, an electronic device, and a storage medium. The method is applied to an electronic device, and includes: acquiring decoding information when decoding a video file; and determining whether the decoding information is abnormal. The method further includes: in response to detecting the decoding information is abnormal, adding an identifier of the video file into a preset blacklist; and in response to detecting the decoding information is normal, adding the identifier of the video file into a preset whitelist, and performing display enhancement processing on the video file.
