Each Hippotizer runs mixes, or groups of media layers, which are assigned to all or part of a video output. This offers intuitive support for splitters (such as the DataPath X4) as each output of the splitter can either be a unique mix, or in the case of a projector blend, part of a larger mix. Multiple mixes can also be sent to a single output for an output preview. Finally, mixes can be relayed to each other to create sub-mixes for A/B Crossfading for example.
