A cognitive skill development method and system for training users in various fields wherein data is added to a video and the video is played on a user device in accordance with such data. Video interruption techniques such as video occlusion are used to interrupt the video. The user is then presented with questions corresponding to the video and the user's response to such questions is solicited and recorded.

Apparati, methods, and computer readable media for inserting identity information from a source image (static image or video) (301) into a destination video (302), while mimicking motion of the destination video (302). In an apparatus embodiment, an identity encoder (304) is configured to encode identity information of the source image (301). When source image (301) is a multi-frame static image or a video, an identity code aggregator (307) is positioned at an output of the identity encoder (304), and produces an identity vector (314). A driver encoder (313) is coupled to the destination (driver) video (302), and has two components: a pose encoder (305) configured to encode pose information of the destination video (302), and a motion encoder (315) configured to separately encode motion information of the destination video (302). The driver encoder (313) produces two vectors: a pose vector (308) and a motion vector (316). A neural network generator (310) has three inputs: the identity vector (314), the pose vector (308), and the motion vector (316). The neural network generator (310) is configured to generate, in response to these three inputs, a composite video (303) comprising identity information of the source image (301) inserted into the destination video (302), where the composite video (303) has substantially the same temporal information as the destination video (302).

Video clips may be automatically edited to be synchronized for accompaniment by audio tracks. A preliminary version of a video clip may be made up from stored video content. Occurrences of video events within the preliminary version may be determined. A first audio track may include audio event markers. A first revised version of the video clip may be synchronized so that moments within the video clip corresponding to occurrences of video events are aligned with moments within the first audio track corresponding to audio event markers. Presentation of an audio mixing option may be effectuated on a graphical user interface of a video application for selection by a user. The audio mixing option may define volume at which the first audio track is played as accompaniment for the video clip.

A first revised version of the video clip may be synchronized so that moments within the video clip corresponding to occurrences of video events are aligned with moments within the first audio track corresponding to audio event markers. Other audio tracks similar to the first audio track may be identified based on audio characteristic parameters. Other revised versions of the video clip may be synchronized.

The technology disclosed herein includes a user interface for viewing and combining media items into a video. An example method includes presenting a user interface that displays media items in a first portion of the user interface; receiving user input in the first portion that comprises a selection of a first media item; upon receiving the user input, adding the first media item to a set of selected media items and updating the user interface to comprise a control element and a second portion, wherein the first and second portions are concurrently displayed and are each scrollable along a different axis, and the second portion displays image content of the set and the control element enables a user to initiate the creation of the video based on the set of selected media items; and creating the video based on video content of the set of selected media items.

Techniques are described herein that enable and assist a user to generate customized video content and alter the video content without altering the customizations. For example, a social networking system may receive, from a user account associated with the social networking system, an input to create video content and add visual customizations to the video content. In some examples, the social networking system may also receive input from the user to alter the video content by altering the length of the video clip and/or adding a second video clip. The social networking system then alters the video content while maintain the previous customizations. The social networking system may then save the altered video content as a draft or share the altered video content to other users on the social networking system.
