Re: Need good video clips for a talk...
Well, to be honest I'm not familiar with aikido as it's taught in the ASU. If you are showing clips that are representative of the type of aikido you do, regardless of whether they are ASU or not, then all should be well. The sticking point is if your club usually does (as an example) a softer, flowing, atemi-less type of aikido but you're showing clips with big falls, strong atemi, etc.
Now if your trying to show the diversity that exists within the aikido community then any public clip is fair game, but I think you should still make some type of distinction between the type that might be encountered in your club and any others.
Alternately you could always make some video of your club members to show, or possibly your sensei if available.
Good luck, I'm sure it will go well.
