Claim Text:
1. A method for providing predictable workflows in animation authoring, the method comprising receiving, at one or more computer systems, a change in a first knot of an animation variable of an object from a first value to a second value, the first knot located at a first frame in an animation sequence of the object; determining, with one or more processors associated with the one or more computer systems, a second frame in the animation sequence of the object that is different from the first frame and that designates knots at the second frame as invariant, wherein no knot of the animation variable exists at the second frame prior to the change in the first knot; inserting, with the one or more processors associated with the one or more computer systems, a second knot of the animation variable of the object at the second frame with an implicit value of the animation variable at the second frame prior to the first knot at the first frame being changed from the first value to the second value, wherein the second knot preserves pose positioning of the animation variable at the second frame using the implicit value; and generating, with the one or more processors associated with the one or more computer systems, an animation curve for the object that includes the second knot at the second frame.
