Hi, I'm somewhat new to Premier Pro so perhaps this is an easy issue to help with. Last night, I began editing a a project and I noticed the source and program windows were a lot smaller than in the past. Also, the program window looks as though it is set to portrait, but my files are all landscape. I can see the correct file (size and dimension) in the Source panel, but when I drag it to the timeline and view in the Program Panel, the file is small, and is landscape in the portrait panel. And the sides of the files are cut off. I've tried viewing in various ways -- fit, 100%, 75% -- but nothing seems to work. Also I've tried changing the dimensions ins Sequence Settings, but this does nothing. Can someone help? Thank so much. Andy

Hi Andy - It sounds like some display setting or Preference has accidentally been changed..? I assume you've tried the usual standard troubleshooting steps -- close/re-open the program; do a hard shutdown/restart; try the same operation(s) in a different project to see if it's a global issue with Premier or one specific to that project/file; etc.. I don't have Premier here (I'm actually an audio guy) but I've attached one of our Premiere courses to the thread (above) -- there are some videos on basic interface settings and Preferences, maybe something in there will be of help (Monitor Settings or Media Preferences?), or maybe one of our video gurus will chime in with a suggestion.. In case it's of any help, here's a link to the Premier Pro online User Guide section on Workspace settings: https://helpx.adobe.com/premiere-pro/user-guide.html?topic=/premiere-pro/morehelp/workspace_and_workflow.ug.js

Thank you Joe! All fixed now. Andy
