Abstract: A method of generating a modified video file using one or more processors is disclosed. The method comprises detecting at least one object represented in the original video file using a computer vision object detection technique. A frequency of motion of the at least one detected object is determined. A playback speed of the original video file or a playback speed of an audio track is adjusted, such that the frequency of motion of the at least one detected object corresponds to a characteristic frequency of the audio track. The audio track and the original video file are combined such that motion of the at least one detected object is synchronized with the audio track.

Abstract: A method of generating a modified video file via a user interface presented on a mobile device including a display is disclosed. The method comprises displaying media corresponding to a first video file on a display of the mobile video device. In response to receiving an initial user input, generation of a second video file corresponding to the displayed media commences. During the displaying of the media corresponding to the first video file, user inputs to manipulate the first video file are received. The second video file is then generated from the first video file as manipulated by the user inputs. A sequence of versions of the video file may be created in a similar manner, which are selectable via a video version stack.

Abstract: A method of generating a modified video file using one or more processors is disclosed. The method comprises detecting objects that are represented in an original video file using computer vision object-detection techniques, determining object motion characteristics for the detected objects, based on a specific object motion characteristic for a specific detected object meeting certain requirements, selecting a corresponding audio or visual effect, and applying the corresponding visual effect to the original video file to create the modified video file.
