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.
The Windows Media Video (or WMV) file format and its associated .wmv filename extension was first released to the public in 1999. It was a proprietary video stream wrapper developed by Microsoft as part of their ASF multimedia container. As of writing, WMV is no longer considered proprietary, since WMV 9 gained standardization as an open standard in the SMPTE 421M specification as VC-1. WMV supports a combination of both audio and video bit streams compressed using one of Microsoft's associated codecs. Also supported is windows media digital rights management for video content.
FreeFileConvert uses tuned encoding for AMV to WMV 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 WMV 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 WMV 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.
WMV in its initial form was Microsoft's implementation of the MPEG-2 Part 2 specification, but has since undergone several revisions, becoming the adopted format for digital video deliver over HD DVD and Blue Ray optical mediums. The format supports high definition video with resolution of up to 1080p.
