--------- my answer was not needed, so I deleted it ---------
What version of Premiere Elements and on what computer operating system is it running?
For now I will assume Premiere Elements 11, 12, or 13 on Windows 7, 8, or 8.1 64 bit.
Select your video on the Timeline, go to Applied Effects Tab/Applied Effects Palette/Motion Panel expanded.
In the middle of the Motion Panel expanded is the Rotation feature.
Please let us know the outcome.
I have the 2017 version of premiere and I cant find the motion tab. Can you help me?
Thank you for the advice. It works.
Now I can buy Adobe Photoshop Elements 15 and Premiere Elements 15.
