During the conference for the presentation iPhone 5S, company Apple Lossless Audio CODEC (ALAC), mentioned that their terminal records video clips slow motion only in 720p format. Probably some have noticed that in reality the quality seems to be a bit worse than that, I have to admit that I thought the same thing when I saw the video clips on the PC, and the ones from gsmarena they made a demonstration In this regard. More precisely, they compared the recordings made by iPhone 5S slow motion too Samsung Galaxy Note 3, both video clips being recorded in 720p format.
According to their findings, the Apple terminal exports the video feed in 720p format, but does not record it at the same resolution. As you can see from the image above, iPhone 5S records slow motion video clips in 480p format, then upscaling to the resolution according to 720p format and from here on users can have fun watching movies. Unfortunately, the quality of the video clips is only great on the 4-inch screen of the iPhone 5S, because on large screens the video clips will not look that great, being slightly pixelated.
Even if Apple is not lying when it says that the slow motion movies recorded with the iPhone 5S are in 720p format, the reality could be different, but we will learn more after other experts analyze the recording method of the video clips
