"I have used twixtor myself for a few projects but I have never had terrific success with it. One of the best filmmakers I know who uses Twixtor really well is my friend Salomon Ligthelm, whom I met when he lived in Dubai back in January last year. He put up a new video a couple of days ago, Gravity, and he was kind enough to write this guest blog post on how to get the best out of it.
Twixtor will not give you as good results as a dedicated high speed camera of course. They do that job incredibly well. You need to light a lot to make them work but as you will read below you need to do the same with twixtor to get the high shutter speeds needed. But for those whose budget means renting a Phantom Flex or something similar is out of the question Salomon guides you through the best ways to make the most out this powerful, but tricky plug-in."
