When i go to render a film clip from my file sare it says that feature is nolonger up. is this because of halo 4 coming out soon?
Yet another feature that was implemented, but is no longer available.
It was dropped when Halo was transferred to 343i.
If you are desperate to capture your gameplay, you could always try and find a cheap Happauge PVR HD on ebay (for HD Footage) or an EasyCap device (MUCH cheaper, but with a significant reduction of video quality)
Hope this helps.
