I have purchased the Vegasaur and I'm very happy to work with it. It is a very handy tool.
However, even I have read the help manual, I wasn't be able to make it work Keyframes tab in Pan/Crop assistant. I would gently ask for a help about how to make it work this keyframe tab. If someone who uses Vegasaur can make me a screen video, I would very appreciate it.
