Bad keypoints

I have tried different size videos and settings, matched May video at 512x512 but the problem persists, for some reason they are located on the side of the head

Can you describe it in detail, does it mean that the head posture does not change?

This is from the May video, I assume they are to be used to track the movement, so if they are not marked properly the ned result will fail.
