Wow, that is very good. So what temporal smoothing and/or deflickering algorithms did you use? I am on a Mac, if you are not, are their Mac equivalents? Thanks.
I used virtualdub's temporal smoother in that example. Avisynth has a bunch of filters that could help to improve this type of scenario as well
Sorry, I'm not sure what the equivalent would be on a Mac. I'm sure FCP should have some filters for flickering, perhaps try those. Some Mac users use virtualization software like virtualbox to access PC programs like avisynth and vdub
But would you agree that your example is slightly different than the OP's problem ? Both have to do with LED lighting and frequencies, but I doubt his is treatable in post. It's hard to say definitively from a single still. Maybe if he posted a short video sample
