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.

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.
