Sealed in the box- the elgato 'turbo h.264 hd' encoding accelerator USB stick. Put in the USB dongle, install the software, and it speeds up encoding of video into the h.264 encoding (mostly for the web, if you want to talk a large file and make it smaller in file size) The quality of the encoded movie is good, and the file conversion time is quick (er than normal)
