Crop, zoom and pan an image

I am sure this is a very stupid question, but all the tutorials I find are for more advanced stuff...
All I want to do is the following:
1) load a still image and turn it into a clip. No problems there.
2) Zoom in the picture and pan it, so that you see only a portion of it in the shot
3) Add some writings to the image.
I just cannot do No. 2. I SEEM to do it, but when I render and then export the video all I see is a small image in its entirety, not the cropped, zoomed, panned version. How do I say "accept changes" so that DV14 remembers it?
