    We are planning to use QML animation for generation picture sequence for TV broadcasting. Basically we need synchronize QML animation with TV frame rate (PAL, NTSC...) How I can do this?

      Hi,

      There is no "supported" API to do this. If you are willing to dig into the internals a bit more (and realize there will be no compatability guarantees), changing some of the settings for QUnifiedTimer (src/corelib/animation/qabstractanimation_p.h) might help -- this timer controls all of the QML animation elements, and has several methods for controlling the rate and consistency of the timer.

      Regards,
      Michael

        This is interesting topic. Could we either somehow use a custom view for rendering or modify the render itself?

            it's interesting. so you need an animations to be based on number of frames , not on time, and then you set the speed(framerate) in frames/second. I will vote for such a suggestion
