Hi
You can correct it..🙂 (see below)
Note: If you have placed the clip on the timeline and then attempt to rotate it using a 270 deg rotation effect, the top and bottom get cut off as they effectively rotate out of the frame. Scaling down unfortunately does not work as the clip has, in effect, been cropped.
SO...
You need to apply a Scale effect FIRST to reduce the size of the image (make it a bit too small so you can see it will rotate in the frame). NOW add a 270 deg rotation. The reduced image will now rotate OK. Readjust the scale to fill the frame height.
Alternatively... and simpler..
Before you add the clip to the timeline right click it in the clip bin and select the Rotate Clip option. Pick.270 degree. (depending on the actual orientation) The clip will now rotate without the need to scale it down. Drag it to the timeline.
