    Movie Lags with Sound REMOVED

    webdesignby
      Maybe somebody out there can explain this one.

      I have the same exact movie clip... both preloaded.

      http://4what.com/test/igocity/igocity_movie.html

      http://4what.com/test/igocity/igocity_movie_nosound.html

      Why would the movie without sound be noticeably... 10 + seconds longer than the movie WITH sound... this makes no sense.

      Can anyone try and explain this?

      Thanks in advance.

          yes - very much expected if your sound was in the timeline and set to "Stream". Stream sounds get
          embedded into the timeline and thereby forcing the animation to remain in sync with it - once
          removed then the animation is not really in sync with anything and it's dependant on the speed of
          the processor during runtime as to ohow fast the player renders each frame.
          with streaming sound, the player will actually drop frames if it has to to keep up with the audio.
          many developers, if needing to sync animation to time but have no need for audio, will "record" a
          bit of dead/empty soundtrack and place it on the timeline - repeating and set to stream to keep the
          animation in sync with the frame rate.

          flash is dynamic - it is not pre-rendered, fixed frame rate video format - it renders on the fly and
          "heavy" animations and/or slower processors will cause slower playback depending. of course the
          differences are very subtle with higher end machines and movies that are well optimized.

            That solved it.

            Thanks for the logical explaination for the seemingly illogical.
