About formats

TOD is a high-definition video recording format developed by JVC and introduced in 2007 with the Everio GZ-HD7 camcorder series. Serving as the HD counterpart to the standard-definition MOD format, TOD files contain MPEG-2 transport stream data with H.264/AVC video encoded at resolutions up to 1920x1080 interlaced, paired with AC-3 (Dolby Digital) audio. The format was developed as JVC transitioned its Everio camcorder line from standard definition to high definition, providing a recording format that balanced HD quality with practical file sizes for the hard disk drives and memory cards used as recording media. TOD files share structural similarities with the MPEG-2 transport stream used in broadcast applications, making them compatible with many professional and consumer video tools that handle transport stream content. JVC organized TOD recordings within a directory structure that includes metadata files for clip management, mirroring the approach used for MOD files but tailored to HD content parameters. The format records at bit rates sufficient for high-definition consumer video, typically ranging from 15 to 27 Mbps depending on the recording quality setting selected on the camera. While TOD is specific to JVC products and was eventually superseded by more widely adopted formats like AVCHD, it remains relevant for owners of JVC Everio HD camcorders who need to access, edit, or convert their recorded footage using modern video software.

SNDR is the audio file format produced by Sounder, an early MS-DOS sound recording and playback utility from the early 1990s. Before Windows brought multimedia to the mainstream, Sounder was among a handful of DOS programs that let PC users capture and play audio through rudimentary hardware — often the PC speaker itself or early 8-bit sound cards. The format stores 8-bit unsigned PCM samples without any file header, relying on application defaults to determine playback parameters. Sample rates were typically low (4000 to 11025 Hz), reflecting hardware limits and storage costs when a 20 MB hard drive was considered generous. One practical advantage was absolute minimalism — with zero overhead bytes, every bit of the file was audio data, which mattered when storage was measured in kilobytes. The format could be piped directly to sound hardware without parsing, making real-time playback feasible on slow processors. Despite its simplicity, SNDR holds a place in computing history as one of the formats that brought digital audio to ordinary PCs. Files from this era occasionally surface in retrocomputing archives. SoX and ffmpeg can interpret SNDR files given the correct parameters, enabling preservation of early digital audio recordings.
