Hi
IMHO "Zoom to cropped area" was never particularly intuative.
Zoom now works like it did in the past.....
Open the Zoom effect window.
Place the red effects cursor line at the start position for the zoom action.
Adjust the yellow corners to the area outlining the start frame of the zoom. (You can force the Aspect Ratio if required)
Click the green cross (top one will do) to set the first keyframe.
Move the red cursor line along to the frame where you want the zoom to finish.
Adjust the yellow cormers for the the frame size you want at this point and click "Apply" to set the keyframe and return to the main screen
The sequence will now zoom, full frame into the area required.
If you want to zoom a cropped frame you can use zoom to do this by setting more keyframe positions, the first two constituting the "Crop" having the same zoom values.
Alternatively you can crop the clip and follow it by a zoom.
I think it's better than before once you give it a try.
