Originally being developed by a Third Generation Partnership Project II, it's used in the third generation mobile phones, 3g2 is basically used as an audio as well as video file format. It is a relatively similar file format to 3gp with some advancements as well as limitations. Specifically, the 3g2 format is for CDMA based mobile phones rather than GSM-based phones, this format is used in fourth generation phones as well. Basically, it is for video viewing, it is also used for transferring photos and videos through the internet. Based on the standards of MPEG-4, it is developed in the light to play the media and to deliver it through the internet connection over high speed.
The OGG file format and .ogg file extension refer to the open source container format developed and maintained by the Xiph.Org Foundation. The format has been in development since the early 90's and initially was designed as an open format for audio compression. Later iterations has seen the format revised into a full audio and video container format with compression codec support of different standards. OGG can be used both in compressed or uncompressed ways and is compatible with different lossy and lossless codecs both for audio and for video. Text can also be added into OGG files as an overlay, all packaged within a single file.
FreeFileConvert uses tuned encoding for 3G2 to OGG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload 3G2 files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized OGG results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent OGG audio with dependable progress tracking.
3g2 format has a contrasting similarity with MP-4 and is a more simplified version of the complex MPEG-4. It is actually designed to accommodate in the cellular phones, its bandwidth requirements are reduced in order to reduce the storage required. It stores and streams the videos and audios as done by the 3gP format. However, the audio streams that are stored by the 3g2, are in the extensions such as EVRC-B, SMV, EVRC-WB, VMR-WB, EVRC, 13k or QCELP.
Though OGG is versatile in the number of codecs it supports, typically only free codecs developed by the Xiph.org organization are used for encoding and decoding. From the lossy family of codecs, audio can be encoded using Speex, Vorbis, or Opus. Whereas Lossless or uncompressed encoding can be done using FLAC and OggPCM respectively. To be competitive against its closest rivals such as Windows Media Video, Real Video and MPEG-4, lossy video compression codec Theora is often used but a lossless format, DIRAC, can also be used to encode video streams.
