Understanding time in FxPlug

Understanding time in FxPlug Learn about time handling in host apps and plug-ins.

Overview

FxPlug 4 uses rational time of CMTime type to handle all timing in the host apps and plug-ins. Time can be in the form of a specific time or duration in an effect, object, or timeline (project). When FxPlug methods use time or renderTime, that time generally refers to the current time that the host is providing or requesting. FxTimingAPI_v4 provides methods to access other time values available in the host app. For FxPlug methods that don’t provide time, you can use FxCustomParameterActionAPI_v4’s currentTime()) to determine current playhead time in the project.
