Hi, I imported a video and its size is 1920 X 1080. It should occupy the whole screen, instead, it looks like this (see screenshot) in premiere pro. It has black blocks around it. After export, it looks like this in the exported video as well. I tried opened a new project and import the same video and it looks fine. However, I really cannot re-do everything again as that will be dreadful. How can I adjust the screen in my previous project? Thank you!
