AMV to AVI Software converts AMV to AVI quickly. Besides AVI, the converter could convert AMV to common video formats and portable devices, for example, BlackBerry, MKV, ASF, AVI, MP4, MPEG, WebM, OGG, WMV, 3GP, and so on.
The converter is an all-in-one video converter that supports more than 100 video and audio file formats and converts to 40 popular formats. It could convert NSV to MPEG, F4V to 3G2, TS to AVI, ROQ to WebM, XVID to 3G2, MP1 to DivX, XVID to ASF, MTV to OGM, and so on.
AMV to AVI Software supports batch conversion and is full compatible with 32-bit and 64-bit editions Vista and Windows 7.
What is AMV?
AMV is a proprietary video file format, produced for MP4 players, as well as S1 MP3 players with video playback. There are now two different MTV formats: the older one for the Actions chip, and a newer one for ALi's M5661 chip. This format for ALi one was ALIAVI.
The container is a modified version of AVI. The video format is a variant of motion JPEG, with fixed rather than variable quantisation tables. The audio format is a variant of IMA ADPCM, where the first 8 bytes of each frame are origin (16 bits), index (16 bits) and number of encoded 16-bit samples (32 bits); all known AMV files run sound at 22050 samples/second.
Low decoder overhead is paramount as the S1 MP3 players have very low-end processors (a Z80 variant). Video compression ratio is low ¡ª around 4 pixels/byte, compared with over 10 pixels/byte for MPEG-2 -- though as the files are of low resolution (96¡Á96 up to 208¡Á176) and frame rate (10, 12, or 16 frame/s), file sizes are small in bytes per second. With a resolution of 128¡Á96 pixels and a framerate of 12 frame/s, a 30-minute video will be compressed into 80 MB.
What is AVI?
There is slight overhead when used with popular MPEG-4 codecs (Xvid and DivX, for example), increasing file size more than necessary. The AVI container has no native support for modern MPEG-4 features like B-Frames. Hacks are sometimes used to enable modern MPEG-4 features and subtitles, however, this is the source of playback incompatibilities.
