Techniques for time-correlated ink are described. According to various embodiments, ink input is correlated to content. For instance, ink input received during playback of a video is timestamped. According to various embodiments, ink input displayed over content is removed after input ceases. Further, ink input is displayed during playback of the portion of content to which the ink input is time correlated.

Examples of the present disclosure describe systems and methods for controlling video playback speed using user interaction. In aspects, user input may be detected during an aspect of video playback. The user input may correspond to, for example, adding user notes or drawings using one or more input devices (e.g., a stylus, a finger, etc.) to a video being played back. A set of features of the interaction may be determined using one or more sensors. Based on the determined features, a video playback speed may be determined and applied to the video. The video may be played at the determined video playback speed for the duration of the detected user input. When the user input is no longer detected, the video playback may automatically resume at the normal playback speed.
