Halo 4 Machinima Mode

I thought it will be cool to have a machinima mode in halo 4. There can be an option in the custom lobby settings if you want to go to machinima mode and create short videos. No longer will you have to go to local if you want to lower your weapons. I think it can also work on forge. You create your setting and then you can act out your machinima. Machinima mode can also have its own theater mode where you can edit your video. What are your guys thoughts, should there be one. Also if you have any ideas post them.

Gestures and Actions that you could buy with Credits to use in Machinima modes.
