Abstract: In an implementation, a software application on a computing device directs the device to extract audio data from a media file comprising the audio data and video data, generate a trim proposal based on analysis of speech in the audio data, and display a visualization of the trim proposal. A user may supply input comprising a selection of at least a portion of the visualization of the trim proposal, in response to which the device trims the media file.

Abstract: Systems and methods for controlling variable-focus functionality to reduce user discomfort in a mixed-reality system implement acts of obtaining a vergence depth of a gaze of a user, determining that the variable-focus lens for providing focus on virtual content viewed by the user is currently configured to provide focus at a depth that differs from the vergence depth, detecting that a triggering condition is present, and, in response to so detecting, selectively dampening an adjustment made to the variable-focus lens. In some implementations, the dampening causes the adjustment made to the variable-focus lens to reconfigure the variable-focus lens to provide focus at a depth that differs from the vergence depth.
