I just got Movie Studio 18 Platinum and when I roll the mouse scroller up and down, it moves my project from left to right instead of zooming in and out. I need to fix this asap. I know how to zoom in and out with the other methods, but I work faster with the scroller, because I'm used to it from my Acid music days. Can someone help me please? Thanks
It doesn't need fixing as that is how it is supposed to work. Remember, this is not Vegas MS and you will have to learn a new set of commands.
To zoom in and out on the timeline, hold down Ctrl + mouse wheel when the mouse cursor is over the Project Window, or use the + - buttons at the bottom right of the Project Window.
To zoom in and out on the Preview Monitor, also hold down Ctrl + mouse wheel when the mouse cursor is over the Preview Monitor.
As far as I have found, this cannot be changed in Shortcuts.
To scroll down vertically in the Project Window, Alt + mouse wheel or use the vertical scroll bar.
