Balks

[U_of_I_Blue]

I have a quick question for everyone. I've read the sections on balks in rule books over and over again, but for me, apparently, seeing is believing on the balk. After my numerous readings I'm still questioning whether certain things that pitchers do is a balk. I think it would greatly help if I could see a video of balks while someone is explaining what exactly makes it a balk.

Can anyone reccommend me a good video that would show balks? Thanks a mil!
