[Paraview] paraview 3.8 save animation

[Carta Riccardo]

Using paraview 3.8,
I loaded 100 .vtu files and when I do File-Save Animation, the .avi duration does not change while i set different fps value, the when I approve all the settings it gives me back this error


Generic Warning: In /build/buildd/paraview-3.8.0/VTK/IO/vtkFFMPEGWriter.cxx, line 197

Could not open codec.

ERROR: In /build/buildd/paraview-3.8.0/VTK/IO/vtkFFMPEGWriter.cxx, line 498

vtkFFMPEGWriter (0xb9b6f48): Error initializing video stream.


what's wrong?

thanks


Riccardo
