iOS 4 contains code, currently inaccessible, to allow for exporting videos directly to Facebook. 9 to 5 Mac reports that the snippet found within iOS 4’s code is labeled “AVAssetExportPresetFacebook,” and allows for video with a maximum height or width of 480 pixels, playing back at 30 fps. If or when activated, Facebook will join other sharing options including email, MMS, MobileMe, and YouTube; it is unclear when Apple might activate the new feature.
