Made an account to cover this issue.
Dylan is pretty much correct but to make it a little clearer I thought I would comment.
From the vague description you had in your video it sounds like you are using a 'dumb' switch to try and configure your link aggregation, which is fine, just not idea.
What you are looking for is 'NIC Teaming'.
Open up 'Server Manager', click on 'Local Server' on the left and then select 'NIC Teaming' under the main properties area.
Under the bottom left windows click on the pulldown menu that says 'Tasks' and click 'new team'.
Name your NIC team something that makes sense and add your network cards to the team.
If you are using a 'dumb' switch you will likely need to go with the 'Switch Independent' mode to get it to work. Great article here on the different modes available: http://blogs.technet.com/b/keithmayer/archive/2012/10/16/nic-teaming-in-windows-server-2012-do-i-need-to-configure-my-switch.aspx
For any of the other modes you will have to look at what Dylan mentioned and go with Link Aggregation Control Protocol (LACP) which is pretty much exclusive to managed switches (afaik).
To make NIC teaming available to your client machines you will likely need to go with some custom software/hardware to get it to work as I don't think it is natively available in win8/8.1 although I don't imagine that you will be able to flood a 10GB NIC on your client machines doing video editing (would love to be proved wrong!).
