The flash-free high-speed video stroboscope for periodic and non-periodic repetitive events presented at the 22th ICHSPP has been improved. All components of the system (the camera, frame grabber, digital phase shifter, frequency synthesiser and the universal counter) are now controlled by intergrated software. The flexibility of the system has been increased by adding a number of features which can be selected and adjusted by the user. For easy documentation each of the captured and stored frames is labelled with the most important parameters of the investigated object as well as the settings of the stroboscope system and the data and time. These parameters are displayed on the screen during the observation of the object and during the recording and play back of the stored pictures and sequences. Unsteady objects, i.e. having a temporal/phase jitter or/and spatial fluctuations can be now investigated using the real-time frame averaging routines newly added to the software. Some system application examples and results are presented
