I try to create a bottom line row sliding some very long text from right to left for my 1920x1080 footage. It doesn't seem to fit in the space, it clips all the text in the left end and right end also. I tried to enlarge the frame horizontal size in the "Sony Titles & text" panel but the maximum allowed is 4096 px and it definitely isn't enough.
How can I make long sliding text at the bottom of my video in Vegas 13?
There really is no easy way to do this in Vegas Pro. The best you can do is make multiple text events and coordinate them following each other across the screen via keyframes on two alternating tracks. Maybe there is a plug-in that does this?
