Hello,

I am trying to save animation using MP4. When specifying frame rate the maximum I could set is 172, if the frame rate is bigger, I get the following error:

ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\IO\Movie\vtkMP4Writer.cxx, line 329  
vtkMP4Writer (000002BF3694AE90): Start() must be called before calling Write()

I appreciate your help.

Best regards,
