Just want to add...
if you just talking of re-encoding your content and not re-render it with new output preferences out of After FX...Cinema4D ect.
...then keep the fps of your source footage. It makes no sense to simple recode a 30fps clip to 60fps.
The file get unnecessary bigger and more performance hungry.....because every of the 30 fps frames gets doubled to match 60 while re-encoding. The content will not get smoother.
The same for the resolution...If you just re-encode them to fit your new projector resolution. Don't do it. Let Resolume do it for you. Use the scaling options in Resolume.
If you really re-render out of your content creation software... than do it. Like Arvol already mentioned...60 fps is much smoother but also need more performance for playback hardware sides. So, your frames might drop.
