"WebMarkers. Markers are used to denote frames with key points or significant events within an animation. E.g. it could be that a character’s animation starts, the camera changes position, or a door opens. Markers can be given names to make them more meaningful at a quick glance. They are available in many of Blender’s editors. " - Calculate object position by 2d markers
