i prefer split them into 2 scenes by saving them with 2 pz files, n compile with window movie maker, adobe premiere, etc... x-). however, its possible to create a diffrent angle view in instance, only with single camera. u can set it up by editing them using graph editor, applying break spline between 2 continous frames, each with diffrent views. n this case, im prefer dolly camera, its the best choice on doing animation i guess...  check my channel in youtube http://www.youtube.com/user/ka06059.
i had save around 20-30 files of most of my videos and compile using diffrent programs. thing still seems to be better i think. i wondered if there is transfering camera too when im new in poser, until now there's still no solutions for it... :-(
