The more I think on it the more I remember - the hardest issue to deal with was that it was a handheld shot so both the flare moved in reference to the frame, the subjects moved with reference to the flare and on occasion occluded the light forming it in the first place. It also popped into and out of an actors hair to make things interesting. I'm saying all this as if the situation was dire but the movement actually allowed the comping of 2D tracked elements from past and future frames whereas if the shot was locked off the flare would sit in the same spot all the time and you'd have to clone similar areas instead of actual
areas - so much is dependent on the particular shot its hard to say what will be involved in your case.
