I agree with you ! UDK 4 could be a really really powerfull tool to make series or movies . There is a lot of Indie media production team for realtime movie!! I never understand why UDK programers put the emphasis in the programation way , because all their marketing stuff shows : cinematics , trailers and storytelling!!!
Come one UDK guys ! please , I can’t believe you made a 4 min tutorial on how to rotate a prop in a scene and nothing at all about how to make a matinee camera cinematic to export for video editing !!!
Do it and I’m sure a lot of people subscribe the 20$ just for that 
I’m a Iclone user and today there is a lot of free-cheap characters tool animation wich export data for UDK :
-Iclone via 3dxchange
-Truebone via Ikinima
-brekel mocap
-ipisoft , etc…
I suggest you to add in the startup window project like “cinematic default scene” and a tutorial to make a simple scene with outside build props , fbx character with animation, camera path and how to export a movie for postproduction process.
Thank you very much!
