iOS camera app ProCam 2 adds “4K Ultra HD” video recording mode as $5 IAP

ProCam 2, a $2 still and video camera app by developer Samer Azzam, has added “4K Ultra HD video recording” via a $5 in-app purchase. Following a technique debuted in September by i4software in the $1,000 app Vizzywig 4K, ProCam 2 uses a hack to splice high-resolution still images together with an audio recording to simulate 4K video recording. ProCam 2’s videos save at 3840×2160 resolution, resulting in large file sizes—over 400MB per minute—with a promised 30 frame per second recording rate for the iPhone 6 and iPhone 6 Plus. A lower frame rate of “up to 25 fps” is promised for the iPhone 5s.

Unfortunately, ProCam 2’s actual performance on an iPhone 6 Plus typically reached only 15 to 25FPS during our testing, with a noticeably laggy shutter during recording. Videos are saved within the app in a 4K Videos folder, in a standard .MOV format that can play with obvious jitters directly on the device. The app is currently at version 4.0.1, addressing an iOS 7-related crash bug, but continues to suffer from many memory-related crashes when using the 4K recording mode. Vizzywig 4K has been reduced in price to $50, and now supports iOS 8.1, though notably with user complaints as to video quality.
