About formats

MTS is a file extension associated with the AVCHD recording format, jointly developed by Sony and Panasonic for high-definition consumer camcorders. Files with the MTS extension contain MPEG-2 transport stream data carrying H.264/AVC video at resolutions up to 1920x1080, paired with Dolby Digital (AC-3) or LPCM audio. The MTS designation is used when AVCHD content is accessed directly from the recording media, as opposed to M2TS files which typically refer to the same transport stream format in Blu-ray disc contexts. Consumer and semi-professional camcorders from Sony, Panasonic, Canon, and other manufacturers write MTS files into a structured directory hierarchy on memory cards or internal storage, accompanied by index and playlist files that organize clips for in-camera playback. The transport stream packaging includes timing information critical for maintaining audio-video synchronization and supports features like random access points for efficient seeking. MTS recordings preserve the full quality captured by the camera sensor, making them suitable as source material for editing workflows. The use of H.264 compression provides an effective balance between video quality and file size, enabling extended recording times on commonly available SD and SDHC memory cards. MTS files are recognized by all major video editing applications and can be imported directly into editing timelines, though some workflows benefit from transcoding to editing-optimized formats for smoother real-time performance.

SOU is a raw audio format designation that functions as an alias for unsigned 8-bit PCM data (u8) in the SoX audio processing framework. Files with the .sou extension contain headerless, uncompressed audio samples stored as unsigned 8-bit integers — each byte represents a single amplitude value from 0 to 255, with 128 as the silence midpoint. Because there is no header, playback parameters such as sample rate and channel count must be specified externally. The default assumption is typically mono at 8000 Hz, though the data can represent any rate the recording hardware supported. The u8 encoding that SOU aliases is one of the simplest possible digital audio representations, predating structured audio containers like WAV and AIFF. Raw unsigned PCM was commonly produced by early sound cards and digitizers in the late 1980s and early 1990s, when storage constraints and limited processing power made headerless formats a practical choice. One advantage is absolute simplicity: SOU files can be read by any program capable of basic file I/O, with no parsing of container structures or metadata decoding required — useful for embedded systems, hardware diagnostics, and educational contexts where audio fundamentals are being explored. The format's minimal overhead also means that conversion to any modern container is lossless and instantaneous, since the raw PCM samples can be wrapped in a WAV or AIFF header without any transcoding.
