“I have a very old but funny video in my old Nokia and I’d like to upload it to the Internet and share it with other people, how can I convert 3GP to FLV so that I can upload it and share it?”
3GP is a very popular video format among some old 3G mobile phones. People might have some old 3GP format videos left in their old phones. One great thing about old things is that you can share them with your friends. And one of the ways of sharing interesting things is to share it online. FLV is one of the most popular video formats online and if you want to know how to convert 3GP to FLV and share it with other people, this guide would be just applicable to you.

Part 1: Basic info about 3GP and FLV Formats

3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones. A 3GP file is always big-endian, storing and transferring the most significant bytes first.

The advantage of 3GP format is that its size is small so it doesn’t take up much space in your mobile device. Therefore, it’s suitable for mobile devices especially for devices with small storage space.

Device support:

  • Most 3G capable mobile phones support the playback and recording of video in 3GP format (memory, maximum filesize for playback and recording, and resolution limits exist and vary).
  • Some newer/higher-end phones without 3G capabilities may also playback and record in this format (again, with said limitations).
  • Audio imported from CD onto a PlayStation 3 when it is set to encode to the MPEG-4 AAC format copies onto USB devices in the 3GP format.
  • The Nintendo DSi supports .3gp on an SD card.
  • Apple iDevices used to support files for playback only as passthrough files, hence no editing ability, but since iOS 9 this has been deprecated meaning files of this format have to be manually converted to H.264.

3GP to FLV

Flash Video is a container file format used to deliver video over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. Flash Video used to be the de facto standard for web-based streaming video (over RTMP). Notable users of it include Hulu, VEVO, Yahoo! Video, metacafe, Reuters.com, and many other news providers. Flash Video is viewable on most operating systems via the Adobe Flash Player and web browser plugin or one of several third-party programs. Apple's iOS devices, along with almost all other mobile devices, do not support the Flash Player plugin and so require other delivery methods such as provided by the Adobe Flash Media Server.

Above is the introduction to the two formats to help you grasp the concept of the two formats. In the next part there will be guidance to show you how to convert 3GP to FLV.
