I have recorded a playthrough of FEAR that's about 3 hours long and recorded at a framerate of exactly 120FPS.
The Youtube Export button is grayed out after selecting that video file in the "video recordings" window, and so are the upload and facebook buttons. There is a video of Portal that plays and the "youtube export" button is colored in and available, and double-clicking on the file makes it playback in Action!
Double-clicking the FEAR video does not do anything; nothing happens and right-clicking shows "Open/Play" and "Export" as grayed out.
