I was experimenting with a shot from TCW that shew Grievous fleet leaving hyperspace from the bridge of a republic cruiser.
Starting with the pan down on the cruiser followed by the separatist fleet approaching and Grievous introduction from ROTS (new dialog) turned out alright. Nonetheless it is a massive shift of pace and some shots of the space battle heating up would greatly benefit the flow. By now I have only experimented a little with TCW footage which obviously looked a bit off. But I might look into this again.
