The title says it all. I have a DSLR and would like to learn more about video, from basics to advanced (I am an intermediate+ photographer). Are there good tutorials I can find online? I could not find much but very basic intros on the web.
The best suggestion I can come up with is to get a book on cinematography. There isn't really much in the way of difference between using a DSLR for video versus any other camera. The techniques are all the same, just the mechanics of the particular camera differ.
The best way to learn the mechanics of a camera is just to read the manual and try it. The way to figure out what you need to use those mechanics to do is to study cinematography in general.
Beyond that, if you have more specific questions, I'm sure we can help you with those in more detail.
