Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Snow Leopard 'Screen Recording' Feature Allows Desktop Video Recording
Similar in many ways to a feature long offered by Ambrosia Software through its Snapz Pro X utility, the option will allow users to capture in motion video their Mac's screen -- essentially video screenshots.
Such a feature will be particularly useful for software developers and educators, as it will simplify the process of creating video tutorials, software demonstrations, and anything else best captured in live motion as opposed to still shots.
Apple has been continuing to seed Mac OS X Snow Leopard builds to developers. The latest build (10A335) was delivered just yesterday. Early reports of that build indicate it's become even more stable and "polished" but no other new features have been noted.
