Embodiments of the present application provide a video recording method and device. The method includes: receiving, by an application of a mobile terminal, a video recording instruction of a user; generating, according to a photographing scene, a video stream that can be edited according to segments, the video stream including at least one frame sequence segment; and uploading the edited video stream to a server. According to the present application, by generating a video stream consisting of at least one frame sequence segment during video recording, where the generated video stream can be edited according to segments, the error tolerance of video capture is improved, and the costs of later video editing are reduced.

In one aspect, an example method includes (i) receiving a first group of video content items; (ii) identifying from among the first group of video content items, a second group of video content items having a threshold extent of similarity with each other; (iii) determining a quality score for each video content item of the second group; (iv) identifying from among the second group of video content items, a third group of video content items each having a quality score that exceeds a quality score threshold; and (v) based on the identifying of the third group, transmitting at least a portion of at least one video content item of the identified third group to a digital video-effect (DVE) system, wherein the system is configured for using the at least the portion of the at least one video content item of the identified third group to generate a video content item.

The disclosure provides a video synthesis method, a terminal and a storage medium. The method includes acquiring at least one video clip. The method includes acquiring a target audio suitable to video content based on the video content and the number of the at least one video clip. T number of the audio change points of the target audio is greater than or equal to the number of at least one video clip minus one, and the audio change points comprise time points at which change in audio feature satisfies a preset condition; and obtaining a video file by synthesizing the at least one video clip and the target audio based on the audio change points included in the target audio.

Techniques are described for pre-exporting chunks of video content during video editing of a video editing project. For example, the chunks of the video editing project can be monitored for changes. When a change is detected to a chunk, the chunk can be pre-exported as an independent chunk that is combinable with other pre-exported chunks and without encoding or re-encoding the pre-exported chunks. In addition, the monitoring and pre-exporting can be performed while the video editing project is editable by a user of the video editing project. When the video editing project is ready to be finalized, the pre-exported chunks can be combined to generate, at least in part, a media file. The generated media file can then be output.

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and a method for performing operations comprising: receiving a video that includes a depiction of a real-world object in a real-world environment; determining a classification for the real-world environment by processing the real-world object depicted in the video; selecting an augmented reality (AR) item based on the classification of the real-world environment and the real-world object depicted in the video; modifying pixels corresponding to the real-world object depicted in the video to generate a modified video that excludes the depiction of the real-world object; and adding the AR item to the modified video at a display position corresponding to the modified pixels.

Exemplary embodiments of present disclosure are directed towards a system and method for extracting objects from videos in real-time to create virtual situations, comprising a computing device comprises video creating and editing module configured to enable a user to record videos and select frames automatically from the user recorded videos thereby transferring the automatically selected frames from the computing device to a server. The server comprises video processing module configured receive the automatically selected frames thereby detecting and extracting objects from the automatically selected frames and transfer extracted objects to computing device and display the extracted objects to the user. The video creating and editing module configured to place the extracted objects on a new frame automatically and allow the user to reposition extracted objects on new frame and enable the user to customize the background and foreground elements in the new frame to create virtual situations.
