I picked up the Colour Correction, Tracking & Transforms and the Effective Keying Techniques DVDs last week. So far, I have nothing but praise. I’ve worked my way through the colour correction DVD and I’m currently watching the keying lessons.
The colour correction lessons are fairly basic/intermediate, but if CC is a gap in your knowledge - like it was mine - then they are definately worthwhile. The whole dvd is really just a thorough run through of all the nodes in the colour and layer palettes, with an explaination of what they do, what each property does and most importantly, why you would want to use that particular node. My only dissapointment is the fairly shallow explaination of lin/log colour spaces and how to work with cineon files, but I now realise this is probably covered in more depth with the Compositing Fundamentals DVD. Then again, you can probably fill this gap without purchasing a whole other dvd.
I’m only a short way into it, but the keying lessons are great so far. Again, there is a pretty big emphasis on why you do things along with how to do things.
The value for money with these DVDs is pretty great. Nice long lessons means the information doesn’t rush by, Matt Linder explains his own preference for particular techniques (ie, only manipulating the red & blue channels, leaving the green channel alone, when CC with a mult node) and again, the is an emphasis on why you would use each technique, which I feel is the most valuable part of DVD or face to face lessons as opposed to just reading the manual.
To compare this set with the other prominant shake dvd training set, CMIVfx’s training DVDs (which I also own), I would have to give the Gnomon videos the thumbs up over the CMI ones. The CMI lessons are only OK - they are a little shallow and rushed and really pretty limited in scope compared to the Gnomon lessons. Value for money is pretty important when you are slapping down 200 odd dollars on DVD training, and the Gnomon shake set is easily above and beyond the CMI set in this regard.
