The specifications of some devices are seemingly immutable, as stated by the company is what you get on the field.
But it has already happened in the past that certain features were unlocked by the manufacturer in a later update or exploited by third-party solutions. Not even the iPhone escapes that rule. With iOS 7.1 the 5s earned the Auto HDR photography, but you could do even more for the video industry.
The hardwares that equips the latest versions of smartphone are capable of recording at resolutions higher than 1080p, technically coming up to 3,264×2,448. The reason these higher modes are not used by Apple is due to frame rate: it would get it to shoot low fps, high visual quality, sure, but bad for what concerns the fluidity of the video being played.
But nothing prevents you to find the most optimal mode intermediate, as did the developer of Ultrakam, paid app optimized for iPhone 5s, but not only. With it, you can indeed reach the 2K resolution with a satisfactory yield.
Ultrakam is capable of recording up to 2,240 x 1,672 with H.264 codec, with the option to choose between 20, 24 and 30 fps depending on your preferences. You can also choose to record with M-JPEG has a lower resolution (1936×1446, in any case exceeding the Full HD). There are also features timelapse and slow motion with different presets available, as well as major adjustments for white balance, exposure and focus. An internal gallery allows you to play back movies made and to export a scaled version of the resolution in the camera roll.
The best self is expressed by this software with iPhone 5s, but those who want to can still dabble in 2K resolution as well on the iPhone 5, iPad Mini iPad first and second generation and the third-generation onwards. In these cases the maximum frame rate is 20 fps. But this is not even the main problem, probably.
The space occupied by these videos is up to 3 GB per minute average. On the iPhone bigger, than 64 GB, you can only bring 20 minutes. It follows then that the combination iPhone / Ultrakam is suitable only for short films, in the absence of the external expansion slot, also becomes strongly recommended to export computers through the options provided by the app itself or from iTunes file sharing.
The cost of Ultrakam App Store is $6.99, a purchase recommended mostly for those who seriously intend to exploit the potential of what it offers and is content at least initially short films before moving on to more flexible products. The developer has also made available an app secondary to $2.99 that allows you to control a second iDevice via Bluetooth LE one dedicated to the shooting.
All this waiting that perhaps Apple itself implements the next-generation iPhone resolutions higher than Full HD with the most eye-catching ” playing time ” to reach, so going to match Samsung and others that are already playing in the field of 4K.
