Here's a questions we are having trouble with.
How do we animate one camera in a scene and then have a second camera with a different view join the animation.
We are essentially doing camera changes throughout the animation. How do you do that?
Thanks for the help |

You will have to composite different takes from different cameras, there's no way, that I know of, to change perspective during a render....
The only way I can think of is to move the one camera to the new position with a keyframe change. ie same camera, several postions. Might look kind of jerky as you would be doing an instant translation. |

I agree with Chester.
If you do decide to try the single-camera-keyframe-change method, be advised it will look strange if you have motion blur turned on.
I prefer to render separate files from different cameras and put them together in an NLE. |

tSNet happens to allow the selection of camera to render from. In theory, it would then be possible to add a number of different jobs, one job corresponding to one camera angle, and set the frame range you're interested in for that particular camera. One shortcoming would be that the range is a simple start-end range. So no multiple ranges for one job. Depending on the number of camera switches needed, this may or may not be a big undertaking.
Anyway, by outputting still images (tga, etc), you could then use the same base filename, and once all jobs are done, you'd have the exact sequence of frames required. Not saying this is the best way to go about it, as it doesn't really leave any room for picking and choosing transition points. I guess I would agree with Frank and say that using NLE to compose the final result based upon separate sequences would be the better way to go. |

I have to agree, overwhelmingly. I've directed live and live-to-tape programming before and I've also shot video that was later edited... the latter is always preferable. Unless you have some sort of time crunch, you're going to be better off rendering each shot you need and then editing them later. It will give you more freedom to tweak stuff, it will potentially improve your timing (watching a real time display is nothing compared to watching the timing of finished footage) and it can help you prevent disaster... say you do a 12 or 20 hour render, switching back and forth from camera to camera (if that is indeed possible) only to find out later that six frames screw up in the middle of the whole thing? That's another 12 or 20 hour re-render and then you'll need to make sure that actually fixed the problem. Or it's another rerender. If you do it shot by shot, you might only have a 2 hour render (or less) to fix the issue. |

I agree with Rotcorp entirely on that one, movie editing is the way to go with that type of thing, not really sure how else you'd get what your asking for just using truespace, for basic movie editing i'd recommend using a program called Movie Maker, it usually comes with windows xp when you install it, you'll just have to search for it :) good luck! |
