I need some help.. to get the following special effects from this video
1)Glowing light rays emitting from the back of the subject (Krishna) at head portion (May be this is a stock footage ?? if so where can I get this,what key word can I use in stock footage search) --- 0.28 secs
2)Shiny effects on gold ornaments of the subject. -- 0.49 Secs
3)Is chroma key technique used on this video to front picture (Krishna) to make the background special effects more effective ??
I have little experience of mixing the stock footage movies with the images using sony vegas pro.I really appreciate for any help you provide.
