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.
First released in 1995 and developed by the Fraunhofer Society, the mp3 audio format is arguably one of the most recognizable audio file format that ever existed. This digital audio encoding format hails from the lossy data compression algorithm family. The format enjoys widespread support and compatibility with most handheld music players, smartphones, computers, and in car stereos most of which have native support for the format. It is also a popular format used for distribution of audio files over computer networks such as the internet. Free mp3 encoders such as LAME and audacity give authors the tools necessary to create .mp3 files.
FreeFileConvert uses tuned encoding for AMV to MP3 conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload AMV files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized MP3 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 MP3 audio with dependable progress tracking.
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.
The MP3 format compression algorithm works through perceptual coding. A technique in which audio artifacts outside the auditory range of the average human, are reduced or 'cancelled out'. The result is a near perfect replication of the original audio sample at a compression ratio of 11 to 1 at 128 kilobits per second. Audio quality can be controlled by such factors as the bit rate, sample rate, among other features. But bits rates being the main determinant of audio quality can be adjusted between the typical range from 128 kb/s to as high as 320kb/s.
