無料オンライン3GPからWMVへのコンバーター

3GP is a multimedia container developed by Third Generation Partnership Project in 1998 for GSM-based (Global System for Mobile Communications) phones. The container requires little bandwidth, storage space and data usage that is why it is ideal for cell phones. It is a standard container for the files sent using MMS (Multimedia Messaging Service).

WMV is a codec usually used for video compression in ASF format. It is possible to open WMV files both on Mac and Windows with almost any player or convert the format to another one. WMV supports DRM protection that prevent users from copying information. It is the main reason why the format is widely used by companies that sell digital video and audio online. Also the format is well-known among users because WMV files are used on popular Xbox 360 devices. Low bitrate makes such files an ideal solution for HD DVD and Blu-ray discs.
