The marker is tiny; the editorial decision behind its placement can matter a great deal.
What a cue point represents
A cue point is typically a timestamp or marker associated with a potential break in the content. What happens at that marker depends on the wider ad and playback workflow.
Placement needs context
A break placed in the middle of a sentence, scene or key sports moment can create a poor viewer experience. That is why visual review can matter.
Galxy Ad Cue Creator
Galxy Pro includes Ad Cue Creator, a tool for setting ad-break cue points within on-demand content. This site does not claim that the tool itself performs ad serving, ad decisioning or server-side ad insertion.
Next step
If you are evaluating a platform rather than learning the concept, compare the operational workflow and the cost model together.
