Finding All Transitions in the Project in Vegas Pro

2 thoughts on “Finding All Transitions in the Project in Vegas Pro”

1. Edward,
   I’ve written a script to apply Transition selected video events. It works OK but I would like to open Vegas Transition Properties window at the end to adjust parameters. InVegas I click right button on the event Transition field and select Transition Properties from the popup menu. Can I do it from a script?
   Thank you,
   Gregory

   1. I’m sorry but that is not an option at this time. You can open effects and generated media but not transitions.
