Hard to tell from the video but it looks to me like the bulge is adjacent to the tire label. Is that right? Do you line up the label with the valve stem? If so, try this:
1. Deflate your tire but keep it on the rim.
2. Push your valve stem straight into the tire.
3. Reinflate your tire.
Betting that fixes it.
It works because the thick rubber where the valve stem is attached is holding the tire bead up. Pushing it in lets the bed seat where it needs to be.
