Abstract: Embodiments of the present disclosure provide, a method, a system, and a computer storage media that provide mechanisms for multimedia effect addition and editing support for text-based video editing tools. The method includes generating a user interface (UI) displaying a transcript of an audio track of a video and receiving, via the UI, input identifying selection of a text segment from the transcript. The method also includes in response to receiving, via the UI, input identifying selection of a particular type of text stylization or layout for application to the text segment. The method further includes identifying a video effect corresponding to the particular type of text stylization or layout, applying the video effect to a video segment corresponding to the text segment, and applying the particular type of text stylization or layout to the text segment to visually represent the video effect in the transcript.

Abstract: Embodiments are disclosed for a method including obtaining a region of interest of a current frame of a video sequence depicting an object. The method may further include determining, by a mask propagation model, a likelihood of each pixel of the current frame being associated with the object in the region of interest of the current frame based on the region of interest of the current frame and a fixed number of previous frames of the video sequence including the object. The method may further include replacing a previous frame of the fixed number of previous frames with the current frame. The method may further include displaying the current frame of the video sequence including a masked object in the region of interest of the current frame based on the likelihood of one or more pixels of the current frame being associated with the object.

Abstract: Embodiments are disclosed for a machine learning-based chroma keying process. The method may include receiving an input including an image depicting a chroma key scene and a color value corresponding to a background color of the image. The method may further include generating a preprocessed image by concatenating the image and the color value. The method may further include providing the preprocessed image to a trained neural network. The method may further include generating, using the trained neural network, an alpha matte representation of the image based on the preprocessed image.
