You shoot in places where you don’t have much control on the lighting.  DE:Noise will allow you to remove camera flashes. Twixtor will allow you to make that special moment last longer.  You get some video from others or have a 2 camera setup. RE:Match Color might be helpful.

You got one of these fancy camera that can do over 120 FPS. Not enough light = noise, check DE:Noise.  At 240 FPS now light strobes like crazy during playback, we have DE:Flicker for that.  It’s not slow enough, super-slowmo it with Twixtor.
