Hi Hunt,
You can find videos on ciscolive365.com. Were you get the video session which explains most of the concept on Nexus.
Just register it and you can search the nexus and you will be able to get all the nexus concept over there.
Eg just type Nexus on search after login it displays something like this you can select which ever you want and play it:
BRKDCT-2237 --Deploying Nexus.
BRKARC-3470 AND MORE ON.
NOTE: some trainings will have only ppt and most of it will have video's.
HTH

Inayath.
