Syncing sensor data with Jitter movie


    Feb 26 2008 | 11:18 pm
    Hi all,
    Does anyone have a good solution for synchronizing sensor data with a
    Jitter movie. I've looked at the various approaches, and I've seen
    the approach of recording data into the audio tracks. Is there an
    easier way of doing this?
    I'm working on a project with dancer and video, and it would be nice
    to be able to synchronize the two for development purposes.
    thanks,
    Peter McCulloch

      i am assuming you want to record the dancer and the output of the sensors at the same time so you can do further experiments with the archive without having the dancer being always present;
      couldnt you record the data into a matirx with one dim, one cell per sensor value, each value being written in at the movie's frame output rate ?
      you could even grab your movie and add a fifth plane for that withthe sensor data written into it .
      rereading the grabbed movie you ll jusy need to unpack it to acces the fifth plane and have it spit out the data while the movie is reading...
      i havent tried it but it could work .
      my 0.00002 cents

      this might be total nonsense, and it is not ment to b a working patch but you l will get the idea :

      jit.qt.record , of course does not work for that purpose as it does not seem to record matrices with more then four planes ( ?)but writing matrixes in .jxf format should do it .
      here is a version i tried which could almost work , although i am not sure it is efficient and i cant get the 9th plane out whch would the sensor data :

      Hi, were you able to log the movie and the sensor data together? I would like to do this for multiple sensors, can i use this patch? I am not familiar with jitter, so do I have to start logging the sensor data into the 9th plane or can planes before that be used? Also, can I save multiple sensors into one plane or would eaach sensor need its own plane?
      Much appreciation for any feedback!
      Thx

      You might be interested in the Jitter Recipe called GestureRecord, which shows a couple of ways to record frame-based parameter values. The portion on the right is the one that I would probably recommend for this.
