how to upload heavy files in sharepoint library?

I have created a library in which videos are going to store. but when i am going to upload media file greater than 50 mb, it gives me an error like 'An unexpected error has occured'.

so my question is how ca开发者_StackOverflown i upload heavy media files as document in sharepoint 2010 library.

There are several places where such a limit might be configured:

For WebDAV it is in the registry (Key FileSizeLimitInBytes) at HKLM\SYSTEM\CurrentControlSet\Services\WebClient\Parameters which is a client-side limit (default 50 MB)!

For IIS it is in the web.config of the site (<requestLimits maxAllowedContentLength="XX" />)

For Sharepoint itself:
Configure maximum file size for a SharePoint web application

In Central Administration, in Application Management, click Manage web applications.
NoteNote

Select the application (for example, SharePoint - 80).

On the Web Applications ribbon, click the down arrow on the General Settings button.

Click General Settings.

Scroll to Maximum Upload Size.

Click OK.
