# TMPGEnc

TMPGEnc or TSUNAMI MPEG Encoder is a video transcoder software application primarily for encoding video files to VCD and SVCD-compliant MPEG video formats and was developed by Hiroyuki Hori and Pegasys Inc.

These include: TMPGEnc Plus, TMPGEnc Free Version, TMPGenc Video Mastering Works, TMPGEnc Authoring Works, TMPGEnc MovieStyle and TMPGEnc MPEG Editor. TMPGEnc products run on Microsoft Windows.

## History

The first beta versions of the TMPGEnc encoder were freely available in 2000 and 2001 and were known as Tsunami MPEG Encoder. The first "stable" version was TMPGEnc 2.00, released on 2001-11-01. In December 2001, sales of "TMPGEnc Plus" started in Japan. In January 2002, the "TMPGEnc Plus - English version" was released. In August 2002, TMPGEnc DVD Source Creator was released and bundled with Sony "Vaio" PC in Japan. In April 2003, "TMPGEnc DVD Author - English version" was released. In March 2005, Tsunami MPEG Video Encoder XPress was released. In August 2005, "TSUNAMI" and "TMPGEnc" were combined into one brand.
TMPGEnc Plus/TMPGEnc Free Version was often rated as one of the best-quality MPEG-1/MPEG-2 encoders, alongside Canopus ProCoder and Cinema Craft Encoder. The popularity of TMPGEnc encoders has spawned various other products and "TMPGEnc" is now used as a general brand name for products such TMPGEnc Authoring Works (a consumer-grade Blu-ray Disc, DVD, and DivX authoring tool), TMPGEnc MovieStyle (a video converter primarily for portable and set-top devices), and TMPGEnc MPEG Editor (an MPEG editing program). TMPGEnc Plus is currently still sold by Pegasys Inc., alongside TMPGEnc Video Mastering Works, TMPGEnc Authoring Works, TMPGEnc MovieStyle, TMPGEnc MPEG Editor, TMPGEnc Instant Show Presenter, and TMPGEnc KARMA..Plus. The TMPGEnc Free Version was updated in 2008 for compatibility with Windows Vista (SP1 included).
