Videos like this are meant for the slope chute since it really isn't unit related.
As for getting the video to show, if you are using a computer you get the embed code of the video. I believe its to the bottom right of the video. (On my phone right now and youtube isnt working) Copy paste that and then before you post you will see HTML under post options. Click on it and click on HTLM on - autoline breaker mode.
Let me know if you need any further help =]
