Canopus Co., Ltd. was a manufacturer of video editing cards and video editing software. The company's focus shifted from enthusiast video cards to other areas of video hardware and software after the release of their Spectra line of products.[http://www.firingsquad.com/guides/tnt2buyers/page16.asp Firingsquad's TNT2 Buyer's Guide: What Happened to Canopus] {{webarchive |url=https://web.archive.org/web/20110606063559/http://www.firingsquad.com/guides/tnt2buyers/page16.asp |date=June 6, 2011 }} Some of their previous competitors included Matrox and Pinnacle Systems. In 2005, Thomson Multimedia acquired Canopus to bolster their Grass Valley broadcasting and network product line.[http://www.thomsongrassvalley.com/news/2005/20051205-Canopus.html Thomson Buys 33{{fraction|1|3}}% Stake in HD Video Editing Leader Canopus, Intends to Launch Public Tender Offer to Acquire Remaining Shares] {{webarchive |url=https://web.archive.org/web/20091016174122/http://www.thomsongrassvalley.com/news/2005/20051205-Canopus.html |date=October 16, 2009 }}

When 3dfx's Voodoo series of PC-gaming-oriented 3D graphics cards became popular in the mid-1990s, Canopus produced the Pure3D, a Voodoo graphics processor-based graphics card with 6 MB of memory instead of the standard 4 MB. When the Voodoo 2 was released, the Canopus Pure3D II was praised for the fact that their cards were shorter than competitors' Voodoo 2 cards. Canopus had a reputation for driver optimization that gave a performance advantage over other cards. They were the cards of choice for Maximum PC's 1998 Dream Machine.

Canopus also released a version of the nVidia TNT that offered a unique internal cable that connected the TNT card to the Voodoo2 based Pure3D II—as opposed to the standard connection with an external cable.

The Canopus DVStorm2 was a realtime video editing card that Canopus discontinued in early 2005. Canopus is also known for EDIUS, non-linear video editing software, and a transcoder application called ProCoder, and their ADVC range of DV (IEEE1394) video conversion units.
