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.
The AMV video file format is a proprietary video container which was created for Chinese made and video enabled S1 MP3 players and MP4 players. The goal of the format was to primarily lower the cost of hardware components and royalty fees required for video playback using other container formats on these video enabled devices. The .amv file type is a modified version of the more commonly known AVI multimedia container with the video codec being a version of motion JPEG (MJPEG) format.
FreeFileConvert uses tuned encoding for OGG to AMV conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload OGG files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized AMV 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 AMV audio with dependable progress tracking.
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.
An open source AMV encoder and decoder for windows exists but is not associated with the original developers of the format. The audio stream within AMV files is encoded using a variant of the Adaptive differential pulse-code modulation or ADPCM algorithm developed by the interactive multimedia association (IMA) but not in its strict form given the inclusion of an 8 byte seed at the start of every frame.
