I'm trying to take a video project I've already assembled and trim it down to 640x640 for posting to instagram.
I figure I need to create a new project with the proper settings (ie frame size of 640x640) and then import my video, then re-export another video that will be the correct size.
However, I'm having issues creating a project with custom settings. I don't see any of the templates that match what I want (not surprising since this is a pretty new format to export video to!) but once I choose a preset to create a project, I was hoping to then alter the frame size via Edit>Project Settings>General Settings. However, the frame rate fields in that menu are grayed out and cannot be altered.
