I want to reset the setting of sony vegas pro 17 to default but for only one project and not the entire software. The reason is that I have two projects made and in project A I have changed the settings according to my need but when I created project B and started masking a video the mask automatically changes its size and now I cant seem to find which settings I've changed and if I reset the settings then my project A will be ruined. I took my a month of editing to finish project A. Please help.
