About formats

DivX is a family of video codecs and a media container format developed by DivX, LLC. The project traces its roots to a hacked version of the Microsoft MPEG-4 v3 codec that circulated in the late 1990s, but the legitimate DivX codec launched in January 2001 as an open-source project called OpenDivX before transitioning to a proprietary commercial product. The codec is based on MPEG-4 Part 2 (ASP) compression and later versions incorporated H.264/AVC and HEVC support. DivX gained enormous popularity in the early 2000s for its ability to compress a full-length movie into a file small enough to fit on a single CD-ROM while maintaining watchable visual quality. This compression efficiency made DivX a defining format of the early internet era, when bandwidth and storage were scarce resources. The DivX Media Format (.divx) container adds features like interactive menus, chapters, subtitles, and alternate audio tracks, bringing DVD-like functionality to digital files. DivX certification became a common label on consumer electronics, with thousands of DVD players and other devices supporting DivX playback natively. The codec also pioneered quality-based variable bit rate encoding that allocates more data to complex scenes and less to static ones, resulting in consistent visual quality throughout a video.

Sound Designer II (SD2) is a professional audio format created by Digidesign around 1988 as the successor to the original Sound Designer format. For over a decade, SD2 was the standard interchange format in professional recording studios, especially those on Macintosh systems. It stores uncompressed linear PCM audio at up to 24-bit resolution with sample rates used in professional production (44.1, 48, 88.2, and 96 kHz). A distinctive technical trait is its reliance on the classic Mac OS resource fork for critical metadata — sample rate, bit depth, and channel configuration — while audio data resides in the data fork. This design worked elegantly within the Mac ecosystem but created portability challenges when files moved to Windows or Unix. A key advantage was SD2's support for multiple channels in a single file and tight integration with the Pro Tools editing environment, enabling non-destructive region-based editing. The format also carried loop points and markers, making it valuable for sample libraries. As Avid Technology shifted Pro Tools toward WAV and AIFF, SD2 usage declined, but millions of legacy session archives still contain SD2 files needing occasional conversion.
