Blend Clip Options: Set the following:

Initial Weight Curve: Sets how the blend is interpolated at the beginning, middle, and end of the animation clip.

Linear: Changes attribute values at a constant rate from the beginning to the end of the clip.
Ease In: Changes attribute values slowly at the beginning and quickly at the end.
Ease Out: Changes attribute values quickly at the beginning and slowly at the end.
Ease In Out: Changes attribute values slowly at the beginning and end, and quickly in the middle.

Rotation Blend: Specifies how to blend between the rotations in animation clips.

Quaternion: (Default) Uses quaternion interpolation between rotations from the first clip to the second clip in the blend. Quaternion interpolation follows the shortest arc between two orientations and produces better blending in most cases.
Euler: Uses Euler interpolation between clips, creating a linear interpolation that blends the values at a constant rate.

Character Set: Creates a character set for the current object. See Characters, groups, and subcharacters.

For more information on the Create Character Set Options window, see Character > Create Character Set > .
