Abstract: In-place conversion of a fragmented MP4 (FMP4) file into an MP4 format without having to create separate files is discussed herein. Audio and visual data is captured by a multimedia application and stored an FMP4 file with an initial moov atom and one or more fragment headers assigned to portions of the audio/video data. Once a capturing session is completed (e.g., user stops recording audio and video), the FMP4 file is converted to an MP4 file by attaching a final moov atom to the FMP4 file and changing the header designation of the initial moov(i) atom from “moov” to an “mdat” designation. This change in designation makes the initial moov(i) atom of the FMP4 file opaque a media player and converts the FMP4 file to MP4 format.

Abstract: Systems and methods provide reframing operations in a smart editing system that may generate a focal point within a mask of an object for each frame of a video segment and perform editing effects on the frames of the video segment to quickly provide users with natural video editing effects. A reframing engine may processes video clips using a segmentation and hotspot module to determine a salient region of an object, generate a mask of the object, and track the trajectory of an object in the video clips. The reframing engine may then receive reframing parameters from a crop suggestion module and a user interface. Based on the determined trajectory of an object in a video clip and reframing parameters, the reframing engine may use reframing logic to produce temporally consistent reframing effects relative to an object for the video clip.
