Host video file on business catalyst server

Thanks Liam. I got some further input from Adobe, posted here in case anyone else has the same question:

You can upload a video on BC site, the file limit is 250 MB, So you can upload the video on BC. Once you have uploaded it to BC, you will get a url of the video like, http://mysite.com/video.mp4

Now go to Muse, use HTML Video tag, http://www.w3schools.com/tags/tag_video.asp
in the video tag code where it says <source src="movie.mp4" type="video/mp4">, replace the source by http://mysite.com/video.mp4 (URL of the video)

The fastest way will be connect to your site using FTP, and upload the file. to see hw to connect to your bc site, take a look to this article

You can chose to upload the file in any folder or in root folder. (Optional)

You can also, upload the file using BC File manager, in Admin panel-> Site manager-> File manager.

You can also put the file in image folder for upload. This will include an additional step. Unless your file is on server, you will not be able to define source in video tag, so You will need to publish site twice, once to upload the file and second after defining the source of the file.
