Encoding Hardware
Alternatively, it is also possible to find hardware solutions for video encoding. Usually in the form of a dedicated computer board that can be added directly to your PC or Mac, these hardware encoders dispense with the need for using the computers own CPU resources to compress video files as they contain a chip set dedicated to the task. This improves encoding speed, often allowing real time encoding of large video files, including HD (720p, 1080p and 1920x1200 (WUXGA)) and outputting to a variety of compression formats or Codecs (h264, VC-1, DivX, MPEG-4 etc.). Some video hardware compression cards also allow HD video streaming over the internet, though at present this is limited by available bandwidth.

Hardware video compression cards are made by companies like Vitec, Enciris Technologies, Blackmagic Design and AJA.

Benefits of Video Compression
For companies that rely on gathering and storing vast amounts of video data such as hospitals, video security firms, film & TV producers etc, compressing video files drastically reduces the amount of hard disk computer data storage space required and this delivers large cost savings. 1 second of uncompressed 1080/25p (full HD PAL) video requires 155mb of data storage, where as a compressed VC-1 video file will require up to 100 times less storage at 1.5mb.
