If you’ve ever recorded a video on your Windows Phone you may have noticed that the extension is .3gp. Well, .3GP is a simplified version of the MPEG-4 (MP4) container format, designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. This is great if you are worried about storage size but it is an issue if you try to play the video on your PC. As it turns out, Windows Media Player doesn’t support .3gp out of the box. Since this is an issue, you are going to need to install the codec for .3gp or an application that supports .3gp. Here I’ve added links for both. Quicktime from Apple supports the .3gp format so you can watch your movies on your PC, and if you’d like to use Windows Media Player I suggest downloading the The Combined Community Codec Pack. This, more commonly referred to as the CCCP, is a collected archive of codecs (video compression filters) packed for Microsoft Windows. This package has pretty much any codec you can think off and supports any type of video format I’ve come across.
