The 3GP file format stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1 or Enhanced aacPlus (HE-AAC v2).The 3G2 file format can store the same video streams and most of the audio streams used in the 3GP file format. In addition, 3G2 stores audio streams as EVRC, EVRC-B, EVRC-WB, 13K (QCELP), SMV or VMR-WB.3G2 is hindered by the fact it is a proprietary format. Bleendreeble's Thirteenth Law of Computing: Any standard format, no matter how awful, is ultimately superior to a proprietary format, no matter how sophisticated== Software for Playback on PC ==*Apple's QuickTime video player is able to play 3G2 on the PC*VLAN ( [[VideoLAN Player]] ) will render the video without sound.*[[MPlayer]] will render both video and sound for 3G2 files.:: testing: Using ( [[SMPlayer]] ) which is a windows version of mplayer with a GUI I was very impressed with all of the video types it would render, including 3g2, both picture and sound. The UI was better than VideoLAN. I recommend SMPlayer for windows. Tested with SMPlayer 0.6.8 MPlayer r29355 downloaded from [http://www.mplayerhq.hu/design7/dload.html this link] on their official web site. During installation I chose to install the extra codecs, which is an unchecked option by default.*Windows Media Player will not play 3G2 with the most windows codecs installed.== Conversion Software ==* ImTOO 3GP Video Converter - successfully converts 3gp to many standard PC video formats. However, the shareware version is limited, it will only do 3 minutes of video. The software is overly expensive for the full version. :: testing: I was disappointed in the video quality post conversion. The software is about 4x overpriced. Maybe there is a serial crack available. [[Category:Computer_Technology]][[Category:Software]][[Category:Digital Video]][[Category:Desktop Software]]
