+1 to everyone that mentioned Philip Bloom. Anything you can so many useful techniques from him.
For beginners though, I am a huge advocate for not turning down contrast, saturation, or sharpness. Unless you have the correct software for color correcting, you're really taking a risk of hurting your footage. DSLR footage holds up terribly if you push it too far in color correction, and unless you're dealing with RED or some other uncompressed footage you absolutely MUST make sure it's exposed properly as well as everything else.
A lot of people discredit youtube, but there are some phenomenal tutorial videos on there. Once you have the rule of thirds down (which I'm sure you do as a wedding photographer), get a basic understanding of the 180 and how to work around it.
And just to reiterate, keep your shutter speed half of your frame rate: 1/50 for 24fps, etc. Also, if you can get your hands on cinema tools or some other frame rate conforming software, play around with 60fps. Even if you're not a fan of slow motion, it can still be pretty fun to play around with.
And definitely make sure to have either a preset WB or custom WB setting, simply because Auto WB will adjust itself automatically during shooting if you're light source changes.
Hope this helps!
