Hi Wayne, you don’t have a small brain. It is a little known fact but anyone called Wayne has a very large brain!
True fact.
What I’m doing in the video is mirroring the animation on both feet in the same time. Then I need to duplicate it so it is twice as long, shift is backwards half a cycle and then cut off the excess keyframes (this is because the other side starts and ends halfway through the cycle).
The final step is to fix the translation. That is what I am doing at that point in the video that you have pointed out.
I am shifting the location of every keyframe backwards exactly half a step distance. However, with the very last keyframe I copied it from the one that I already fixed which is 1 full step behind where it needs to be on that specific frame.
I hope that makes sense. Try not to get bogged down into the exact things that I’m doing on each frame and think about it as the entire process.
To recap:
1. Delete one side (except for the first key because Blender needs the channels to paste the data to)
2. Copy the exact mirror over to the other foot.
3. Duplicate the cycle then offset it half a cycle (12 frames)
4. Delete the excess frames.
5. Shift the translation back half a step on each frame
6. Have a cup of tea and high five yourself because you did something awesome
