It might be surprising that Apple, who is known to exercise such a vice grip over apps allowed into the iTunes App Store, would have let a $1,000 price tag pass!
i4software’s Vizzywig 4K lets you produce and distributed 4K videos from your iPhone 5s. A complete 4K video workflow all from the convenience of your 2013 iPhone model Unfortunately, for now, it will have to be only that model and only on iOS 7. If you want to keep on using this app, you shouldn’t upgrade to iOS 8 until further notice.
Technically speaking, the app captures 4K photos at 24 images per second. This can then be compiled into one single real 4K video. It might seem like a roundabout way of doing things, but it is perhaps the only way to accomplish something so ambitious on a platform that isn’t capable of supporting such. It does, however, have its advantages over direct video recording. The most immediate one is that all frames are captured using the full 8 megapixel sensor of the iPhone 5s, meaning that you have raw, uncompressed quality available. Technically speaking, Vizzywig 4K captures at a rate of 72 MB/sec (576 Megabits per second), something that not even the likes of the LG G3 can accomplish given Android’s 4 MB/sec rate limit.
