from this frame to this one

    May 26 2006 | 1:22 pm
    I'm new to this mailing list.
    I've been trying for four hours to read a film from this frame to this
    other frame and i just cannot find a way to do
    So here i am.
    Can you guide me ?

      There are several ways to do this.
      One could send the message "frame my_first_frame_number" and then "jump
      1" until you've gotten to the frame you want (my_last_frame_number -
      Or one could calculate the frame number based on the movie's timescale
      (gettimescale / getfps = number of time units per frame) and then use
      looppoints to set the first and last frame (@loop 3 will do a
      single-cycle read from the beginning to the end).
      Or you get set @editmode to 2 (frame) or 3 (frame_true) and set
      looppoints directly in frames.
      Make sense?

      The object uses QuickTime time units rather that
      what you're referring to as "frames" when specifying things
      like loops. I'm not sure whether this is potentially a language
      problem or not - that is, your use of the phrase "from this
      frame to this other frame" refers to a time point in a QuickTime
      move rather than an explicit frame [The QuickTime confidential
      appendix in the tutorial goes over some of this]. If so, you should
      have a look at the loop and looppoints messages to the object, either in the help file or the online Reference
      Manual page (which is accessible from the help file).
      If you *really* mean a frame, you have access to the frame
      message which will display an explicit frame of a QuickTime
      movie [the getframecount message can be used to find out
      how many of them there are in a movie]. Again, have a look at
      the Reference manual pages.
      The Jitter tutorial covers the use of the "get" messages (e.g.,
      getframecount, getduration), which you'll find useful.

      i'm not sure about the convenience of this message in this list...
      however, the matter is jitter related and perhaps some of you have
      already run over this situation.
      i've installed windows xp system pack 2 in a power book pro 2.0 GHz.
      macosx partition is about 70 Gbytes and windows partition is 20 Gbytes.
      maxmsp seems work properly : it was installed without any problems,
      objects instantiate and msp produces sound.
      jitter doesn't behave normally:
      when trying to install it, the installer claims for .NET framework
      and suggests a visit to the download page.
      after downloading and installing .NET framework from the suggested
      page and trying to install jitter again , the installer displays a
      box claiming for version 1.14...
      actually, the installed version from this page was 2.0...
      once version 2.0 has been uninstalled and version 1.1 downloaded and
      installed, the jitter installation appers to be normal. the problem
      arises when launching maxmsp-jitter : the launching process never
      ends, even crashes... sometimes, in the scrollbars of the max window,
      some rests of the regular splashscreen image of maxmsp remain. when
      trying to click somwhere, maxmsp doesn't respond anymore and must be
      killed to regain control.
      after uninstalling jitter, maxmsp works again
      reinstalling maxmsp and jitter again yields the described behaviour.
      am i missing something? must i delete some archive somewhere? should
      i reinstall windows?
      many thanks

      do you have quicktime installed?

      Hello Jose,
      You will need to make sure your Windows partition has Quicktime and Java
      installed for Jitter to function properly.
      The .NET nag is just an installer quirk, and won't be present in the
      next version of Jitter.

      thank you Andrew and Scott.
      yes. they are installed, but I haven't tested them. i'll start
      reinstalling QuickTime if it didn't work, will try reinstalling Java
