    Abstract: A novel audio ducking method that is aware of the loudness levels of the audio content is provided. The method specifies a minimum loudness separation between audio tracks that are designated as masters and audio tracks that are designated as slaves. The method attenuates the volume of the slave tracks in order to provide at least the minimum loudness separation between the slave tracks and the master tracks. The amount of attenuation for a slave is determined based on the loudness levels of the slave and of a master.

    Abstract: In one or more embodiments, a computing device is configured to modify an original video by applying a machine learning model. The computing device obtains multiple training data sets, with each particular training data set including an original video and a corresponding modified video. One or more frames from the original video are cropped to generate corresponding frames in the corresponding modified video. The computing device trains a machine learning model, using the training data sets, to generate modified videos from original videos such that one or more frames in the original videos are modified to generate corresponding frames in respective modified videos. Once the machine learning model is trained, the computing device obtains a target original video and applies the trained machine learning model to the target original video to generate a target modified video.

    Abstract: In some implementations, a user can specify an audio control curve for an audio track. The audio track can include an audio signal that is sampled at a specified rate. The audio control curve can be used to generate an audio control signal that can be sampled at the same rate as the audio signal. The audio signal and the audio control signal can be combined to produce sample-accurate adjustments of the audio signal. In some implementations, the audio control curve can correspond to gain adjustments for the audio signal. In some implementations, the audio control curve can be used to adjust the amplitude of the audio signal at particular frequencies. The audio control curve can be used to adjust treble or bass levels during the playback of an audio track, for example.
