The MP4 file format and the .mp4 filename extension refer to the MPEG-4 part 14 digital multimedia format developed by the Moving Picture Experts Group. It is used as a multimedia container to wrap encoded digital video and audio streams, including subtitles and still images if required. In recent decades, the format has been popularized as one of the main standards for streaming media over the internet and other computer networks and for the digital distribution of large multimedia files. MP4 supports a large number of compression audio codecs allowing files in this format to maintain a relatively small size without discounting playback quality.
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 MP4 to OGG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload MP4 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.
The MPEG-4 Part 14 is standardized as part of the MPEG-4 format in ISO/IEC 14496-14:2003. It is recognized as a container format for audio and video streams and references several filename extensions of which .mp4 is one. The MPEG-4 Part 14 is in many ways identical to Apple's QuickTime format which formed the basis of MPEG-4. However, there are slight differences in compatibility with other previously standardized MPEG features and the added support for IOD or initial object descriptors which describe elementary data streams and set profile information of the resources needed for content playback.
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.
