What are the differences between Track Motion and Event Pan/Crop?

I am new to Sony Vegas and was wondering what are the differences between those tools, the Track Motion and the Event Pan/Crop?

It Seems to me that both control the zoom in/out on an image and create any movement in a video.



So what's difference?

Thank you.What are the differences between Track Motion and Event Pan/Crop?The track motion is applied to all events on the track. If you only have one event on the track then they are similar. If you have multiple events you can adjust each event independently with the event pan/crop.



It the same story for track effects versus event effects.
