    Abstract: Techniques and devices for creating a Forward-Reverse Loop output video and other output video variations. A pipeline may include obtaining input video and determining a start frame within the input video and a frame length parameter based on a temporal discontinuity minimization. The selected start frame and the frame length parameter may provide a reversal point within the Forward-Reverse Loop output video. The Forward-Reverse Loop output video may include a forward segment that begins at the start frame and ends at the reversal point and a reverse segment that starts after the reversal point and plays back one or more frames in the forward segment in a reverse order. The pipeline for the generating Forward-Reverse Loop output video may be part of a shared resource architecture that generates other types of output video variations, such as AutoLoop output videos and Long Exposure output videos.

    Abstract: Techniques and devices for generating multiple output video variations for an input video based on a shared resource architecture. The shared resource architecture reuses and shares computational and gating results from one or more operations to create the multiple output video variations. The shared resource architecture applies a frame-time normalization of the trimmed and stabilized video to produce a trimmed stabilized normalized video and, thereafter, uses the trimmed stabilized normalized video to precompute one or more video parameters that can be shared with multiple output video variations. The shared resource architecture can then generate multiple output video variations using the shared video parameters.

    Abstract: An electronic device displays, in a first user interface, a media item that corresponds to a sequence of images in a first display mode, which is one of a plurality of user-selectable display modes for the media item. The device, responsive to detecting an input, displays a display-mode selection user interface that concurrently displays representations of the media item, including a second representation of the media item that corresponds to a second display mode. The device detects an input on the second representation in the plurality of representations of the media item. In response, the device selects a second display mode in the plurality of user-selectable display modes for the media item, which corresponds to the second representation in the plurality of representations of the media item.
