suddenly it's all zoomed in

Sorry, my english is so so... I am a temporary user and want to finish one project and I am not getting there. I add clips to my sequenz and after a few (in this case three) every other clip I add to it, it is completely zoomed in and half the content is not visable because it is too close. I have not changed anything the clips are all the same source and I havent touched any buttons i dont know. I tried restarting, starting a new project and try all over again... it keeps on happening. what am I doing wrong.
