Help please, keyframes created BUT animation is not moving

[Fordz]

So I’m currently in Lesson 129 (Creating the Walk Cycle) of The Ultimate Blender A-Z Guide. I’m in the part where I’m in pose mode and have to create keyframes. So I select all bones in frame 1 and press I to insert a keyframe, then I copy the pose to the opposite side in frame 13.

When I press spacebar to play the timeline, both keyframes are static. Isn’t frame 1 supposed to transition to frame 13, like all the limbs slowly moving until they match the pose in frame 13? But the thing is, frame 1 does not move at all, and when the playhead goes to frame 13, the pose just suddenly changes.

In the video, when you scrub the timeline, frame 1 transitions to frame 13. But when I scrub the timeline, like when you play it, there’s no transition. Any ideas as to what might be going on?

Hey Fordz! So the issue is that somehow you changed the interpolation of your keyframes to constant. With all the bones selected, select all the keyframes in the timeline and hit the T key and change it back to “bezier” to have a smooth falloff. In fact you’ll want to change it to liner otherwise he will have a slow start and end. Linear will give better result:
