Noises are a problem to diagnose, and it might help if you found someone else to ride the bike while you move around the bike. Be careful, though, do not get too close to moving parts!

The trouble is that you have the crank, chain and pedals in the same area, and all could be a source of the noise. Does the bearing feel rough if you turn the crank by hand?

Doesn't feel rough... Everything is re-tightened. I checked the chainrings as well - nothing is loose. I thought I saw lateral movement of my chainrings under full load, hence why I checked for all of that wasn't sure if it's normal or not.

For no expense you can take the bearing seals off your BB by carefully prying them off with a very thin blade of some sort and check the condition of the grease. If it looks like the grease is mostly gone or gunky just flush it out and add fresh grease. Check for feel and noises before buying a new one. Also make sure your chainring bolts are tight and it's not something else making the noise. I'm with Geepig about the noise as it's nearly impossible to tell what it is in the video.
