Since the iPhone 4G was released on 7 June 2010, it has been ever increasing in popularity. As the apple in iPhone fans' eyes, iPhone 4.0 OS has the attractive features as the following:
Multitasking: It enables you to run your favorite third-party apps and switch between them instantly.
Folders: You can simply drag and drop the apps to organize them into folders.
Improved email: You can see messages from all your accounts in a unified inbox, organize messages by threads, open attachments in third-party apps and much more.
Watching videos on iPhone 4G anywhere anytime is surely a great convenience, however, we should convert the videos of various formats to the format supported by iPhone 4G. Then a MP4 Converter comes as a great help. And according to my own experience, when we convert videos to MP4 with a MP4 converter, we can usually set some advanced parameters like bit rate, frame rate, video encoder and much more. Here I have looked up some information on Apple site to refer to when we set the parameters during video to MP4 conversion for iPhone 4G.
Profile: MPEG 4
Video Codec: XVID/H.264
Bit Rate: 1800K
Video Size: 640*480
Frame Rate: 29.97
Aspect Ratio: 16:9/4:3
Audio Codec: AAC
Bit Rate: 128000
Sample Rate: 44100
OK, this is the optimized parameter settings for video to iPhone 4G MP4 conversion. Of course, you can also leave it to the default value of the MP4 converter. A powerful MP4 converter will do a good job automatically for you and Leawo MP4 Converter is such a capable MP4 converter which I have selected from internet and I am satisfied with its capability.
