Thanks for this. Yes that's the issue. I can work on the earlier version which doesn't have the zoom issue but crashes when exporting. I have found that if I break the movie into 5 minute sequences,they each export. I plan join them up to see if the full 50mins will export without crashing since (I am assuming) the 10 imported mp4 will be less load than the full layered 50 w all the fx. Will update
Await the newest version eagerly. Thanks
