Abstract: Systems and methods for determining playback times for content items presented in playlists are disclosed. Techniques described herein include identifying a first content item in a content reel comprising a plurality of content items, and determining that the first content item has an undefined display duration. In response to the first content item having an undefined display duration, a display duration for which the first content item should be displayed when presented in the content reel is calculated. The content reel can be provided for display at a client device, such that the first content item is displayed for the display duration.
