Can't see videos my my IPad mini

I Have transferred photos and videos from my my cannon 600d to my MacBook Pro and the videos play fine but after synch to IPad mini I can only see photos. I manage music and photos manually and have checked "include videos" and also made sue I can view videos in the setting of the ipad. I already have 2 videos on the iPad taken via iPhone and save from an email. Can anyone help me please.?
