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 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.

Abstract: Uploading of a video file is performed by transcoding, processing and uploading portions of the video file in parallel, to reduce total processing and upload time. The processing of the video file may include applying associated augmented reality effects to a raw video recording, to generate an enhanced video recording for transmission and viewing at a recipient device. The uploaded portions of the video file may be assembled into a fragmented file format such as fMP4, in which portions of the video file are stored as fragments.

Abstract: Image augmentation effects are provided on a device that includes a display and a camera. A simplified augmented reality effect is applied to a stream of images captured by the camera, to generate a preview stream of images. The preview stream of images is displayed on the display. A second stream of images corresponding to the first stream of images is saved to an initial video file. A full augmented reality effect, corresponding to the simplified augmented reality affect, is then applied to the second stream of images to generate a fully-augmented stream of images, which are saved to a further video file. The further video file can then be played back on the display to show the final, fully augmented reality effect as applied to the stream of images.
