How To Make an Advanced Loading Bar in Sony Vegas Using Photoshop and Sony Vegas I Have Made a Simple Loading Bar and I Want To Upgrade it. Basically I Want To add a Spark animation To The Top of The Bar That Moves With it until it Loads Completely, I Thought That only Timing Would be The Problem and I could Just use a Push Transition but it doesn't Seem So, Any Ideas?
If the spark footage has an alpha channel, as is likely, then make sure, it is activated - right-click on the event, launch Properties, and check that Alpha Channel in the Media tab is set to Straight.

Now, animate the Spark's position in its Pan-Crop window to track the leading edge of the bar.



Offhand, I don't know if you parent a track, is the parent's Pan/Zoom inherited by the child tracks. Try it out. For Track Motion, it is, but that reduces the resolution of the footage pre-compositing to fit the project dimensions, so I avoid it.
