HTML5 Video Upload from Muse To Business Catalyst.

Hi all excuse my complete and utter ignorance of all things techniacal, I am new and I am in the process of learning.  As the title suggests I am trying to upload a video that I want to include in the design of my site to Business Cataylst via the publish feature in Adobe Muse.  I am running into difficulty however with this warning message  ".mp4 is bigger than 100MB and is too big to be uploaded."  Is there any way around this besides making my video smaller?  Any help would be greatly appreciated.  Thanks.
