Hi folks.
I wonder if there's a way to handle this situation...
I have been given an MP4 to edit, and when I load it into Movie Edit Pro MX Plus, it appears side-on in the viewing window.
So I select the movie on the timeline and apply:
Effects --> Movement effects --> Rotation/Mirror
And I do a 90° rotation.
That brings the movie the right way up, but it then appears full height in the viewing window, but only about a quarter of the viewing window in width.
