How to restrict transition FX (flash) to one track?
Hi! I’m new here, and relatively new to Sony Vegas. I’ve been trying to figure this thing out, and you guys seemed helpful to someone else’s question so I thought I’d see if you could help me out as well!
What I’m trying to do is use a transition effect on text, and not have it appear past a certain extent (geographically on the screen). I’m trying to create a help video, with screen capture video on the bottom layer, a caption bubble (static image) as the second layer, and text on top of the caption bubble. Whenever the text changes, I want there to be some sort of transition effect, to make it more difficult for the viewer to miss out on the fact that the text changed. However, I don’t want the effect to make anything happen outside of the caption box. I hope that makes sense.
So, what I’ve done is used the “track motion” button on the text track to size it and place it such that it coincides with the caption box. However, this doesn’t appear to keep transitions from moving beyond the layers boundary, and thus far I haven’t been able to figure out how to do so.
Here’s what I see in the middle of a transition between two events in the text layer:

Am I going about this completely wrong? Thanks for any help!
