[gary orish] “Hi, I’m afraid I find the pan/crop tool cumbersome and counter-intuitive to use. One has to INCREASE the frame handles in order to DECREASE the size of the image, for instance.”
Think of Pan/Crop as being a camera, i.e. zooming in (making the image bigger) or zooming out (making the image smaller) on the screen.
“Right now, I’m trying to move a video image off to one side, and crop the edges.”
Use Pan/Crop to crop and then Track Motion to move it to the desired location.
“I also noticed that sometimes the handles (and dotted lines) disappear from view and the position panel is grayed out. The only way to get them back is either to delete the clip and start again with a new pan/crop FX, or to keep undoing what I did until the position handles are back in view. (Is there any way of managing this directly, in the View menu perhaps?)”
Use your mouse wheel to zoom out on everything or enter a very low value in the Zoom (%) box option under Workspace. FYI, it only goes down to 12.5 %.
