| Description | The AMV format is a proprietary video file format mainly used with MP4 players, especially those made by S1 MP3 players. AMV files typically contain video content encoded with the AMV codec, which uses low-resolution and low-bitrate compression techniques to optimize playback on portable media players with limited processing power and screen resolution. These files often include audio tracks encoded with the ADPCM (Adaptive Differential Pulse Code Modulation) codec. AMV files are commonly used for storing and playing short video clips, animations, and music videos on portable devices like MP3 players and cell phones. |
| Technical details | The AMV format is a proprietary video file format specifically designed for portable media players manufactured by the company Actions Semiconductor. The AMV format typically uses a proprietary video codec developed by Actions Semiconductor. This codec is optimized for low-power devices and portable media players, allowing for efficient playback of video content while minimizing battery consumption. AMV files commonly have a resolution of 160x120 pixels or 220x176 pixels, which are suitable for small screens found on portable media players. The frame rate is usually limited to 15 or 20 frames per second (fps), ensuring smooth playback on the target devices. The AMV format supports a limited color depth, often using a palette of 256 colors or less. This helps reduce file size and conserves memory resources, making it feasible for playback on portable media players with limited hardware capabilities. |
