Thanks a lot for getting NodeCanvas. Sorry, there are no video tutorials at this point, but the documentation is quite thorough. Of course please feel free to ask anything if you have questions and I will be glad to help you out.
The documentation is good, however you really do need to develop video tutorials (see the mecanim video tutorials). A picture is worth a 1000 words! After viewing the mecanim tutorial I was able to get animations up and running in just a few hours.
