|In vegas, make sure you have the "Media Generator" tab open by going into View and slecting it. Once done, go find that tab (it may be along the window with Explorer showing), you should see (by default) a "Large Tiles" "Small Tiles" and so on, on the left part, select "Credit Roll". This will get you your ending credits. As for your beginning titles, just lower, you will find "Text" but depending if you just want text alone at the beginning with a black background, you may have to slide you're whole video to the right to make room or you can simply have it over you're running video fading in and out.|
