This technology came out from siggraph this month. May 2012
It amplifies both color and movement BY FREQUENCY in video. Picks up and magnifies subtle changes in colors and move within your chosen frequency and amplifies it in video. For example you can chose to amplify only movement of frequency of ONE GUITAR STRINBG and only that sriggn's movement will be exargerated.
It can amplify blood change sin face and pick up pulse in arm from normal video.
It can pick up and amplify movement in only one direction and only with say the movement frequeny of a baby's breath thus making baby's breathing suddenly visible in a video where it was not.
