Vegas Pro 17 aspect ratio not working right in pan and crop. For example, if I enter 1920 for the width, it calculates 1281.7 for the height. This is with the aspect ratio lock on.
Pan/crop controls, including Aspect, are well explained in the in-program resources, although the learning curve is steeper than you may expect. This is especially true if your source, project, and output aspect, or PAR do not all match.You may want to start with the event context menu and Track Motion, and work your way up if it doesn't do what you want.
