I'm getting confused over some of the animation basics, and of course, my animations look like crap. I am noticing how the examples have multiple root types of the skeleton. I hope I'm even putting that correctly. I understand some of the basics from the youtube videos, but my knowledge is weak in the area of how to construct the bones in the first place.

And then there's some obfuscated mention in another post of placing multiple keys in the feet to create an anchor for the skeleton that I don't understand.

Are there any tutorials I could follow? Thanks for any info or insight.

This is pretty hard to explain in text, but I'll do my best.

First of all my basic character setup usually looks like this:

Let me try and break it down a little more

The root bone is the main "parent" of your skeleton.
bone1 is a child of root
bone2 is a child of bone1
This means if you translate the root bone, both bone1 and bone2 will follow.

Now in my first hierarchy setup, you can see I have a hip bone. The hip bone is what I translate when I need to move the entire character around. If you want a character to jump, you translate the hip bone and all the children follows it, this goes for rotation and scaling as well. But lets say I want to get some more subtle secondary motion in, but only on the pelvis, like maybe squashing it a bit while it moved down just as the hip moves up, then I can move the pelvis down a bit and scale it on the Y axis. It will still follow the hip bone, but it will also get its own motion.

I will be creating more videos, soon I'll create one that also goes through my workflow in Photoshop etc, and I'll create an entire character from scratch along with some animation.
I highly recommend checking out The Animators Survival Kit. It's an amazing book that will teach you far more than I will ever be able to.
Also take a look at the Animation Workshop video, you might pick up some things there.

Hope it helps. If you have more questions about animation, don't hesitate to ask.

Thanks for the response. I'll look this over and see how I can tweak my stuff.

There was a post in the following thread that mentioned it might be possible to anchor the feet to single locations without the legs moving.

What you're looking for is IK with pinning or effectors. This is not something we have planned to implement, but maybe we'll get to it eventually. Placing a couple of extra keys on the feet is not that big of a deal though, doesn't take very long and with a little practice you can do it really quick.

By "keys," do you mean putting a couple of extra bones into the feet? Or does that indicate to put root bones into the feet?

Keys means keying a bone's SR or T transform by pressing the key button. The pinning stuff is not implemented yet.
