A stratum allows you to view a media object from a specific perspective to consider its visual or editorial content. Strata are annotation layers that build the basis for logging Interplay MAM assets: each stratum can be segmented, each segment is defined by an In and Out mark, and then these segments can be annotated. For more information about strata and segments, see Understanding Strata.

When you play an Interplay MAM video asset that was annotated in the Logging pane or Interplay MAM Cataloger, you can display stratum annotations of type “text” as an overlay in the Media viewer. You can select the stratum from which the annotations are displayed. The timeline in the Media pane shows alternating orange and blue sections that represent the individual segments of the selected stratum. Gaps between segments are represented by light gray sections, and overlapping segments by a darker shade of the same color.
