Just Guys I Need Your Help To Make Some Changes Of My Tech Videos To Upload... So Comments On The Above Question...

Note:
Quality Of Video Should Not be Compromise In Any Way...
Sound Should Be Decent...
While Adding Water Mark, Video Format Should Not Be Changed...

I Have Used MAGIX Movie Edit Pro 16 Plus HD...
But Its Too Confusing For Me...
