It is often desirable to synchronize animations and media. However, this is complicated by the fact that media playback can be delayed by loading or buffering making it difficult to reliably play an animation along with media. The property is used to determine what happens when media and animations are played together. A value of Grow (default) specifies that animation timelines do not need to be synced and will play when specified regardless of the state of other media in the timeline. A value of Slip on the other hand, specifies that an animation will wait (slip) until media is ready to play. The diagrams below illustrate this behavior.
This Storyboard has a of Slip. Note that the DoubleAnimation (and any other non-media children of the Storyboard) does not progress unless the media timeline is also progressing. If the media takes a while to load, or if it is buffering, the animation will wait (slips) with it. This allows animations to synchronize with a single media file.
