Sony Vegas Pro 12 | Motion Blur
Quick and simple tutorial. This is for an object flying-in. Only takes a few minutes to learn, and it's quite nice. You can use this method to apply the blur for flying in text, picture, video... Anything you can animate to fly in. Also works Vegas 11, 10, 9...
Oh yeah, the whoosh effect:http://www.freesfx.co.uk/sfx/whoosh
