How to animate Rotation of a PNG image in VSE? I selected the Transform effect green rectangle, then I moved to frame #10, and lastly, I changed the Rotation value. Shouldn't a Keyframe have been made at that moment?
I am starting to suspect that of all things animatable, this is not one of them, is it?
It's animatable, but it isn't automatic. Move the mouse cursor above the Rotation slider, and hit i when you want to add a keyframe.
