AVI recording and offline parameter settings

[Chandan]

Hi,
Thanks for the AVI recording details.Seems like this process takes a huge amount of disk space.A particle simulation example takes huge amount of physical memory(as the particle numbers grow).The vector method of recording the simulation looks a better option.Can some one please comment on the following

1) how can I configure to run the world view recording for a specified amount of time?

2) can this be done without the worldview window being displayed?(in background)

Thanks in advance
