title: How to change the resolution of the stage in MIT Scratch
body: <p>The default resolution of the Stage in MIT Scratch is 480x360 in a 4:3 aspect ratio. I want to change it to a 16:9 aspect ratio, with a 720p resolution. Is there any source file or script that has to be edited in order to do this?</p>
  
  <p>Also, I found this link: <a href="https://scratch.mit.edu/discuss/topic/52369/" rel="nofollow noreferrer">https://scratch.mit.edu/discuss/topic/52369/</a> but I cannot understand how to do so. Here is a source file from that link: <a href="https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as" rel="nofollow noreferrer">https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as</a>    (Go to the line #51 to see the width and height of the stage: <a href="https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as#L51" rel="nofollow noreferrer">https://github.com/LLK/scratch-flash/blob/053d2b2eaf172ed2889211f5f57621731183f5c1/src/scratch/ScratchObj.as#L51</a> )
  How to edit that source file, and then how would I compile it? Whenever I open that ActionScript file, It opens in Adobe Animate CC with black text on a black background (which I can't read).</p>
  
  <p>Can anyone give me the step-by-step instructions to do that?</p>
