The SetRate() function of vtkFFMPEGWriter is not working

Hello, VTKer


I am using vtkFFMPEGWriter to write a video, no matter the frame rate I set, the output video is still 600 frames/sec.

The code I used has been attached. Can anybody check the problem for me? Thank you so much.


Regards,
YiRui
