perhaps you could create more than one camera (i hope you're not animating your persp camera... a definate no-no)
then you can just batch render the frames you want or use the command line to render all the cameras without having to do any input
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
