HyperCam uses Windows API tools for screen capture and call of this function with the same arguments, but at different times, takes a different amount of time. At the same time it is not known in advance how much time this will take. Therefore, it turns out that one frame is recorded with one duration and another frame with another other duration. Therefore the file is created with variable frame rate.
