This video deals with
1. What are breaks on dislocation lines?
2. What are jogs and kinks?
3. Dislocations intersection to form Jogs and Kinks?
4. Movement of jogs
Addendum: @10:59, I made an error when I said the b1 screw dislocation slides downward; it actually moves in the opposite direction as the b2 screw dislocation. However, the remaining portions of the explanation are not impacted by this error, thus that is the only fix. FYI, dislocation always moves in the direction perpendicular to its tangent vector (irrespective of nature).
