I have tried to replicate the cube and bones as in the video but can not replicate the bending action. I have placed the cursor at the bottom, middle, and top of the bones without any success with rotating them. Edit mode comes closer to replicating the rotation better than pose mode. In both cases my cube is badly distorted. Any thoughts on what I am doing wrong? I am using 2.83.
This is a short tutorial on bendy bones in 2.8 https://www.youtube.com/watch?v=-MgU7qOkufU, I tried it and it worked with my version of 2.82. There were more steps then in the tutorial above, but they were easy to follow.
