Abstract: A novel method for creating multimedia presentations in a media editing application is provided. The method selects a portion of a media clip and retimes the selected portion of the media clip from a first playback speed to a second playback speed. The method defines a transition interval for a discontinuity between a first section of the media clip with the first playback speed and a second section of the media clip with the second playback speed. The media clip is played back according to a smoothed curve that is constrained by the transition interval, the first playback speed, and the second playback speed. The smoothed curve transitions gradually from the first playback speed at the start of the transition interval to the second playback speed at the end of the transition interval.

Abstract: Artistic styles extracted from one or more source images may be applied to one or more target images, e.g., in the form of stylized images and/or stylized video sequences. The extracted artistic style may be stored as a plurality of layers in a neural network, which neural network may be further optimized, e.g., via the fusion of various elements of the network's architectures. An optimized network architecture may be determined for each processing environment in which the network will be applied. The artistic style may be applied to the obtained images and/or video sequence of images using various optimization methods, such as the use of scalars to control the resolution of the unstylized and stylized images, temporal consistency constraints, as well as the use of dynamically adjustable or selectable versions of Deep Neural Networks (DNN) that are responsive to system performance parameters, such as available processing resources and thermal capacity.
