Sonny vegas is the wonderful software of movie editing . When , I first install it , I did not know what are the main function of it . But , I saw a wonderful Video and I understood what are main function of Sony Vegas Software . Which I am sharing with you :

• With sony vegas , you can change your video background , , In sony vegas you will get Chroma key with this you can change your video background . But it is pre-requisite that your background must be green or red because when Sony Vegas changes background , it has power to transparent green or red color background and it show history just like photo shop , if you learn how to change background in photoshop. You will see generally in news channel where the presenter come in the whole map of world . That media work is also done with this key .
