Colossus 2 is an internal video recorder which plugs into PCI Express x1 or x16 slots. It contains the same studio quality video encoder which is used in the HD PVR 2, and can record both HDMI and Component video at up to 1080p30, with support for 1080p60 passthrough. Like the HD PVR 2, Colossus 2 also has built-in hardware support for H.264 Variable (VBR) and Constant bit rate (CBR) encoding, video downscaling, and a logo inserter for putting 'bugs' or logos on your recordings or video streams. Colossus 2 uses a high quality Analog Devices video front end, and a Magnum studio quality video encoder. The Magnum encoder supports data rates are from .2Mbits/second to 13.5 Mbits/sec CBR, with VBR datarates running to about 21 Mbits/sec. Colossus 2 runs under Windows 10, 8, 7, Vista and Windows XP.
