I was wondering if you could give me some insight on how to approach creating the effect seen in the Late Night with Jimmy Fallon - Show Open. The link below is where you can see the Show Open (sorry I have no control over cutting out the short 10sec ad at the beginning). Anyway, there are these fast street scenes with circular glowing rings. Some shots have more glow rings than others. I'm not sure if this was done in-camera or post. If it was done in post, would you have any ideas on how to replicate that effect?
