WebTech360 - Technically, the iPhone 4 can take 5 Megapixel resolution photos, and HDTV1280 x 720 video or simply 720p. For example, a video file recorded by an iPhone with a length of about 50 seconds has a file size of more than 60MB. In many practical aspects, we can hardly do anything with a video less than 1 minute long and with a size of more than 60MB, so converting the format is extremely necessary to apply in such situations.
If you search the Internet, you will find many ways and supporting software to perform the above process, but most of them require the Quicktime application to be able to rotate Apple's *.MOV file. In the article below, the author will apply this by using Microsoft 's available utility , which is Windows Live Movie Maker , with the ability to support a wide variety of video files: wmv, asf, wm, m2ts, m2t, mov, qt, avi, dvr-ms, wtv, mp4, m4v, 3gp, 3g2, k3g, mpeg, mpg, mpe, m1v, mp2, mpv2, mod and vob.
All you need to do is start the program, then drag and drop the *.mov file into the right window with the text: click here to browse for videos and photos . And to rotate the video, just press the Rotate right button on the Menu, then select File > Save Movie > For email to reduce the size of the video, along with the original size of the file:

Along with this test, Windows Live Movie Maker completed the process in about 21 seconds, and the size was only 9.38MB . Besides, if you want to convert the format as you like, use the Create Custom Settings option from the Save Movie menu:

One thing to note here is that Windows Live Movie Maker is not available during the Windows 7 installation process, so you need to use Windows Live Essentials 2011 to download the application package. After completion, the Live Essentials installer allows users to use Mail, Windows Live Mesh, Bing Bar, Outlook Connector Pack, Writer, Family Safety, Messenger Companion, Messenger, Photo Gallery and Movie Maker . Good luck!
