Embodiments described herein enable user interaction with a video segment. A hit-zone file, which includes hit-zone data, is produced and stored for a video segment, wherein the hit-zone data corresponds to spatial regions that define hit-zones for hidden objects included in the video segment. The hit-zone file is provided to a computing system so that when the computing system displays the video segment the hit-zone file adds hit-zones for the hidden objects included in the video segment. The hit-zone file is produced separate from the video segment. Each of the hit-zones is defined by a different portion of the hit-zone data and corresponds to a different one of the hidden objects included in the video segment. The spatial regions that define the hit-zones for hidden objects are not visible to a user of the computing system that views the video segment with the hit-zones added.
