MPEG converter

An .mpeg file holds an MPEG program stream: video and audio multiplexed together using the original MPEG-1 or MPEG-2 standards. These files come from Video CDs, DVD-authoring workflows, and older capture hardware, and they remain readable by virtually every conversion tool.

Batch files can each use a different output. Nothing uploads for local conversions.

Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.

Where MPEG comes from

The Moving Picture Experts Group finalized MPEG-1 in 1993 as ISO/IEC 11172 so movies could fit onto compact discs, then delivered MPEG-2 as ISO/IEC 13818 in the mid-1990s for broadcast television and DVD. The program stream defined in those standards is the container .mpeg files use to this day.

How MPEG works

  • Program streams were engineered for reliable storage media, in contrast to the error-hardened transport stream used for broadcast
  • MPEG-1 video typically runs at 352x240 or 352x288 around 1.5 Mbps, the Video CD profile
  • MPEG-2 adds interlaced video, higher resolutions, and the profiles used by DVD
  • Audio is usually MPEG-1 Layer II (MP2), with Layer III appearing occasionally
  • Regular I-frames in the GOP structure make seeking predictable and cutting straightforward

When to use MPEG

  • Handling digitized VHS or Video CD content
  • Preparing input for DVD-authoring applications
  • Ingesting legacy broadcast and surveillance archives
  • Transcoding to MP4 so old captures play on modern devices

Strengths and limitations

Strengths

  • Universally decodable, with all underlying patents expired
  • Simple, robust structure that tools have parsed for thirty years
  • Predictable seeking thanks to frequent keyframes

Limitations

  • MPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality
  • No support for modern subtitles, chapters, or attachments

Compatibility

Desktop players on every operating system decode MPEG-1 and MPEG-2 program streams, and no licensing barriers remain. Browsers never adopted the format for the HTML5 video element, so web delivery requires conversion first.

The program stream carries essentially no descriptive metadata; the specification predates any notion of embedded titles or tags.
