I guess many of us, when dealing with lens flare effects, try to do them in After Effects or such by using Knoll’s Light Factory Pro or similar plugins.
I’d urge you to take a look at this one, Video Copilot’s Optical Flares plugin. It has something I was trying to replicate procedurally in AE, to no avail: changing the flare’s properties when it crosses the image frame limits without keyframing, via what they call dinamic triggering .
One wishes EIAS was able to interface with it.
