The problem of recording with mocap lib

[ke-fuquan]

     I use the mocap sample "mayaClockServer" in the "devkit/mocap" directory. I attach "hours","minutes" and "seconds" to a cube's translate attribute , after the mayaClockServer.exe runs , the cube was moved,until this everything works fine. 
    Now i want to record the cube's movement, i user  "recordDevice -d clock -dr 50;" to trigger the CAP_CMD_START_RECORD and that makes  mayaClockServer.exe starts to record,an d after a while , i use "recordDevice -d clock -st off;" to stop record. 
    But after all of this , i got nothing in the maya scene, i thought the recording may write the motion as keyframes in the scene , but it dose not. 
    Now i am asking, what does the recording in the mocap exactly used for? how can i make it work ?   thanks for any reply.

i now know that the data comes from mayaClockServer in maya is stored in the animation curve , and should be output as mov file , and then load it into the scene to become keyframes.

is there a way to convert the motion data in the animation curve to keyframes directly ?
