Synchronize animation timing with the Adobe Captivate Classic timeline
If you notice when previewing a project that an animation file you added as an object is displayed for a longer or shorter period of time than the duration of the animation file, you can synchronize the animation with the Adobe Captivate Classic Timeline to give you greater control over the timing.
In the Property Inspector (Window > Properties), select Synchronize With Project in the Timing area.
If the animation file was originally recorded with an audio track, you may find that the audio track is choppy after selecting the Synchronize With Project option. The best solution is to separate the animation file and audio so they can be used as two distinct objects in the project.
