About formats

MKV (Matroska Video) is an open-standard multimedia container format developed by the Matroska project, which announced the format in December 2002. Named after the Russian matryoshka nesting dolls, the format is built on the Extensible Binary Meta Language (EBML), a simplified binary variant of XML that provides a flexible and forward-compatible structure. MKV can hold virtually unlimited numbers of video, audio, and subtitle tracks within a single file, supporting codecs from H.264 and HEVC to VP9 and AV1 for video, and AAC, FLAC, Opus, and DTS for audio. A standout feature is comprehensive subtitle support, handling formats from simple SRT text to complex ASS styled subtitles and bitmap-based PGS tracks from Blu-ray discs. MKV also supports chapter markers, attachments (such as fonts needed for styled subtitles), and tagging metadata, making it one of the most feature-rich containers available. The open specification ensures that any developer can implement MKV reading and writing without licensing fees, which has driven widespread adoption across media players, streaming tools, and encoding software. The ability to encapsulate virtually any codec combination in a single, well-organized file has made MKV the preferred container for high-quality video distribution, archival, and personal media libraries.

PRC is an audio file format associated with Psion handheld organizers, particularly the Series 3 and Series 5 lines from the 1990s. These pocket computers included built-in microphones and basic voice recording capabilities, storing captured audio in the PRC container. The encoding is typically ADPCM-based (Adaptive Differential Pulse-Code Modulation), balancing file size against audio intelligibility given the severe storage constraints of early PDAs — the original Psion Series 3 had just 256 KB of RAM doubling as storage. PRC audio is generally mono at low sample rates (often 8 kHz), optimized for speech rather than music. One advantage was tight integration with the EPOC operating system (later evolving into Symbian), letting users embed voice notes directly in agenda entries and database records. The compact file sizes — a minute of speech consumed only a few kilobytes — made it feasible to store dozens of memos on devices with minimal memory. While PRC audio is a legacy format today, conversion tools exist for extracting recordings from archived Psion devices, which remain collectible among retro computing enthusiasts.
