On the surface, the video capture functionality sounds a little more robust, as the PS4 is able to record 15 minutes of game footage. What we don’t yet know is at what resolution and at how many frames per second it is able to capture.
While Sony might not be putting the game capture functionality behind the PlayStation Plus subscription, with the PS4 some features and additional functionality will require a subscription; this we are sure of. Sony has not been clear on what those features or functionality might be. We do know that Sony has said so far that all social features as well as automatic updates will not require a PlayStation Plus subscription.
Sony apparently considers the video capture functionality as part of the social features of the console.
