Hi BMS
Just took a quick look at the Voodoo camera tracker, it looks like it works a bit like Boujou. The test clip was good. I haven't heard of that piece of software so I can't really comment on how good it might be, but if you like it and it works good for you, then great! 3de, Live and Boujou I think are just the 3 most well know and widely used tracking software, but I'm sure there are lots of others out and about that are just as effective.
