Hi, I’m working a character with the armature and I have two questions:
After rendering I watch the animation and I discover that the final frame it’s
an image of the same work but older, I don’t know how that happened and I don’t know how to delete it, because it’s not in the secuence of the armature that I want to animate.
When moving the armature i can move and loc, arms and head, but hands doesn’t keep the poses from the diferent frames, i move them and they stay in that pose during all the animation.
The extra frame is probably from a previous animation. It isn’t really part of the animation, it is just an extra picture sitting wherever Blender puts its renders. When Blender plays back, it runs through images in sequence and since this image is there, it plays it too. To get rid of it, go to the folder Blender is using (where it saves the images) and delete pics any with a frame number bigger than the number of frames in your current animation. Another way to get rid of it is to increase your current render by a couple of frames so Blender overwrites the old frame.
Usually when working with armatures, you mainly key rotations (Rot) more than locations (Loc). Not every time, but mostly (Depends in part on if you have IK or FK setups).
When you move/rotate a bone and key it, that’s where it stays until you key it somewhere different. If you want it to go back to a previous position, then go back to that frame, copy the bone’s position (use the little arrow that says “copy to buffer”) then move forward to the current frame and press the other arrow (paste from buffer), then key the bone at this frame. I’m not sure if this really answers your question.
