Unwanted Delay on Sound Control (windows)

  • Dear Friends,
    I'm having a problem with significant delay on sound effects running with video. I'm using video mixer for showing looped video, and on the same control button, a 100 value to sound volume entry of my movie player.
    Mixer is faster than sound control (nearly 1s).
    Is this normal, Is there any way to pass this problem ?
    Thank you for your help

    Maybe add a curvature actor to 'ramp' it up?

  • Dear webmammuth,

    I am afraid I don't really understand the problem. Do you mean that you change the volume from 0 to 100 and you don't hear the change until 1s later?


  • Yes mark, that's my problem.
    Sound don't react as fast as video.
    100 is shown on sound volume on the actor, but is heard nearly 1s later.
    Don't know why.

  • Dear Webmammuth,

    A delay like that is not normal. The audio and video should be closely synchronized.
    Are you working on Mac or Windows?
    What version of the operating system?
    What version of Isadora?
    Are you playing a QuickTime movie file, or some kind of Windows format (AVI/WMV)?
    Best Wishes,

  • Thank you for your answer.
    Isadora version f24.
    Windows Seven.
    Will check the movie type, think it's quicktime photojpg.
    Audio and video are in sync on AV movies, just delay on volume command.
