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.

PVF (Portable Voice Format) is a simple audio file format designed for voice message storage in Linux-based telephony systems, most notably ISDN4Linux and its vbox voicemail application. The format emerged from the European ISDN ecosystem of the late 1990s, when Linux servers increasingly handled PBX and answering machine duties over digital phone lines. PVF files store raw signed 16-bit PCM samples at 8000 Hz mono, preceded by a minimal plain-text header specifying data format and byte ordering. This deliberate simplicity is one of the format's primary strengths — with no compression and a human-readable header, PVF files are trivially easy to parse, pipe, and manipulate using standard Unix tools. The 8 kHz rate matches the Nyquist requirement for telephone-bandwidth speech (300-3400 Hz), making PVF a natural intermediate format for voice processing pipelines. Another advantage is cross-architecture portability: the explicit byte-order declaration means PVF files move between big-endian and little-endian systems without ambiguity. The SoX audio toolkit provides native PVF read/write support, enabling straightforward conversion to modern formats.
