Vertical Black Bars, Aspect Ratio Problem. NEED A FIX Heres the problem.

When exporting in Adobe Premiere CS5, there is an output tab. Once clicked it should show me what the video will look like when its exported but this is not the case and even when uploaded to youtube it isn't correct. Here are some screen shots to prove what I am talking about. I should add, when looking at the exported version. I have even checked off aspect correction to off and on then on and off. Also, matching sequence settings doesn't work either.

Ouput Tab



Presets



Clip Settings (Proves its actually in 480)



Finally here it is after its exported, how do I fix this. Many suggestions would help. THANKS!
You have set the wrong pixel aspect ratio (that has nothing do with the aspect ratio of your video resolution). Notice how you're source footage (the mpg file) has a pixel aspect ratio of 1.21 but you export it with a pixel aspect ratio of 0.91. Also your sequence is set to a pixel aspect ratio of 0.91 (that value in parenthesis next to your resolution in the export settings where the source specs are listed).

Change your sequence settings to the same pixel aspect ratio as your source (1.21 or simple the widescreen setting in the drop down menu), aswell as in your export settings. Though your might wanna export with a square pixel aspect ratio of 1:1 which is what youtube prefers. You will have to change the resolution for that though.
