The iPhone is a multimedia smartphone designed by Apple Inc; announced on January 9, 2007. Though lacking of a physical keyboard, iPhone has lots of functions, from universal text messaging, email, to visual voicemail, web browsing, Wi-Fi connectivity, etc, which can be operated via its virtual keyboard. And most important, it's a portable media player. It supports music, audiobook, podcast, application and video. Fun is always with you if an iPhone is in your hands.
So, most iPhone users like to watch movies on this beautiful handset. However, according to iPhone's official page, there are many technical specifications as follows for iPhone video file:
Video Format: MP4, MOV, M4V
Video Size: up to 640x480
Video Framerate: up to 30fps
Video Bitrate: up to 1.5Mbps for H.264, or 2.5Mbps for MPEG-4
Audio: AAC up to 160Kbps, 48kHz
MPEG-4: A collection of methods defining compression of audio and visual (AV) digital data; introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) under the formal standard ISO/IEC 14496; uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.
H.264: A standard for video compression; known as MPEG-4 Part 10, or MPEG-4 AVC (for Advanced Video Coding); the latest block-oriented motion-compensation-based codec standard developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG).
MP4: Movie or video clip that uses MPEG-4 compression, a standard developed by the Moving Picture Experts Group (MPEG); commonly used for sharing video files on the Internet.
MOV: Common multimedia format often used for saving movies and other video files; uses a proprietary compression algorithm developed by Apple Computer; compatible with both Macintosh and Windows platforms.
M4V: MPEG-4 file extension used for videos downloaded from the Apple iTunes store; includes music videos, TV episodes, and full-length movies; similar to a .MP4 file, but may be copy-protected using Apple's FairPlay DRM copyright protection.
AAC: Compressed audio file similar to a .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
For this reason, if you have an iPhone and want to play movies on it, you need to convert the video with correct settings first. Once you have Any Video Converter, this operation can't be easier.
Launch Any Video Converter, you'll find Apple iPhone/iPod Touch MPEG-4 Movie in the Profile drop down list.
