-    <p>The project settings define mainly how the video appears while you edit the project. The video 
resolution and aspect ratio affect the appearance of the previewer. If the resolution and aspect ratio do not 
match those of your footage, the video may look squished or letterboxed. These settings can be changed at any 
time by using <guiseq><gui>App menu</gui><gui>Project Settings</gui></guiseq>.</p>
+    <p>The project settings define mainly how the video appears while you edit the project. The video 
resolution affects how much detail the previewer can show. If the resolution of the project does not match

     <note>
       <p>When you import the first video file the project settings are automatically changed to match. See

-    <title>Pixel aspect ratio vs display aspect ratio</title>
-    <p>Digital images are composed of a grid of <link 
href="http://en.wikipedia.org/wiki/Pixel";>pixels</link>, which may or may not be square. In some cases, you 
may need to set the <link href="http://en.wikipedia.org/wiki/Pixel_aspect_ratio";>pixel aspect ratio</link> 
(PAR) for the image to display correctly. On the other hand, <link 
href="http://en.wikipedia.org/wiki/Display_aspect_ratio";>display aspect ratio</link> (DAR) is the 
mathematical ratio of width:height for the whole image.</p>
-    <p>In <app>Pitivi</app>, pixel aspect ratio and display aspect ratio are related to each other through 
video resolution (width and height). Once your resolution is set, setting the DAR will influence the PAR and 
vice versa. You can use either DAR or PAR, whichever you are most comfortable with.</p>
-    <note>
-      <p>You can use the ratios already provided in the combo boxes, or input a custom aspect ratio in the 
text entry below (using a syntax such as "4:3" or "1.3333", although the decimal version is less precise).</p>
