I understand what you are saying about studying the videos. I was just saying that I need to understand more the lingo (tweeners, etc) and the basics of using the NLA.
most of the terms used in animation, come from the animation industry (Disney etc),... before computers and digital rendering.
Traditionally,. an Animator would draw the main poses of the character, which were needed to produce a specific section of animation,. these main poses were known as Key frames,. (frames of film)
These hand drawn Key frames, were then handed over to the apprentice animator,. who was told to create all the frames in-between each of the main “key frames” to create a section of continuous animation.
The apprentice animators given the task of making the in-between frames,. became known as Tweeners, and the task became known as tweening. and it’s still the same, even when you’re using a computer to calculate the in-between frames,.. the process is known as tweening, and there’s a variety of types of tweening filters.
NLA (Non Linear Animation)
Traditionally animation is created on a time-line,. by placing Key frames at specific points in time,.
NLA allows you to create “Clips” of animation which can be moved around in time, and placed where you ant the action to occur.
You’d create your animation as normal,. by creating key-frames and using tweeners,. and once you’re happy,... you’d create a Master NLA clip, which takes all the animation information, and places it into a virtual container, which can be moved around and adjusted in the time-line.
Creating a master clip from your animation can (optionally) clear away your original key-frames.
If you want to work with the key-frames instead of an NLA clip,. you can import the data from the clip, as key-frames on the time-line.
NLA clips can be saved to your “My Clips” section of the browser, and reused in different scenes,. (you can also create and add your own folders to store animations for specific scenes, or specific figures.
NLA clips can also be used together to create more complex animations,.
for example: if you had an animation of a seated figure,. who reached up and scratched it’s head,. and an animation of a figure standing, who raises it’s arm,.. waving
you could use NLA clips , and define which parts of the figure, which each clip effected, to create a seated figure, who starts waving,. and then stands up and scratches it’s head.
or any other mixture of the motions from the two, or more,. different animations you’re working with.
Hope it helps
