title: how to scale all the compositions in a after effects project?
body: <p>I have a after effects template whose preset is 1920*1080 , but I need the output to be in 20 * 8 sq feet. How can I change the whole project composition settings to fit the screen ?
   I tried to scale the project by using "File -> scripts -> scale composition .jsx" but I change the width, then the height changes simultaneously. </p>
