I had a brief look into this recently, and looked into the use of the OSG Xine plugin functionality for this. It appears Xine uses some timing control to keep video playback speed constant, which also seemed to work fine from slow- or fast-running OSG apps with integrated video(s) (It appears to skip or repeat frames, respectively) Although the plugin doesn't directly make speed control available, you can extend it by sending commands to xine such as: xine_set_param (_stream, XINE_PARAM_SPEED, XINE_SPEED_SLOW_2); for finer control, according to source code documentation from xine, you can use more precise speed parameters: XINE_PARAM_SPEED / 4 <-> XINE_PARAM_FINE_SPEED / 1000000 Probably you can tune this to achieve 25fps from within OSG, but I have no experience up to what accuracy this is. Hope this helps, Gerwin
