I started a project in 1920x1080, now i need to convert the project to 1280 by 720.. i made the change within hardware settings but i can't find any other places to change.. what other changes do I need to make? my canvas tick marks are still 1920x1080 and when I export a movie or still sequence they are still 1920x1080.. i tried starting a brand new project with the proper settings but various elements don't seem to get imported back so that route doesn't work..
