iOS 5 ups video export resolution in third-party apps to 1080p


In addition to the newly discovered ability to render 1080p videos on A4-powered devices by scaling down high-definition content on-the-fly, a tipster pointed out that the iOS 5 software development kit ups the maximum resolution for video exports from 720p all the way up to 1080p. The iOS 5 media framework now rocks a new video export option: A 1920-by-1080 full HD preset. Previously, programmers calling system APIs were only able to export video content up to the 720p resolution. The change has been spotted in the export preset strings of AVAsset, an abstract class of AV Foundation framework which has been around since iOS 4.

Programmers use the AVAsset class to work on a detailed level with timed media assets such as videos and sounds. It lets them examine, create, edit or reencode media files, get input streams from devices, manipulate video clips during realtime capture and playback and more. It is now clear that iOS 5 enables devices such as iPhone 4, iPad 1 and 2 and fourth-generation iPod touch to both output 1080p videos and export video content in 1080p. The finding is another indication that the rumors of an eight-megapixel camera with 1080p video capture on iPhone 5 are likely true because there is no point in iOS 5 supporting 1080p video exports if users won’t be able to acquire full-HD content on their iPhone 5.
