How can I move down the background image,so the word OUTSOURCING would be just below the logo? I think with video bg I have the same issue too... Top part of it is too high up.
You can use a tool like Firebug or similar for inspect your source code of your site in your browser.
A tool like this will give you information about the selectors and the path where they are located, the line number and the name of the file that contains this selectors.
Once you have this you can add or change the values, in this case you have this class:
background: #FFFFFF url(http://idevsky.com/images/1.jpg) no-repeat center center fixed;
Here you can change for example the value center center to something like center top.
