[Paraview] vtkPVCameraCueManipulator (0x8353f8e60): Too few keyframes to animate.

[Anton Shterenlikht]

I made an animation interactively in PV 4.1.0.
I checked that the animation is fine with mplayer.
I recorded my steps with Tools -> Start Trace.
When I try to run the resulting python script
with pvbatch I get this error:

$ pvbatch --use-offscreen-rendering zpart1.py
ERROR: In /wrkdirs/usr/ports/science/paraview/work/ParaView-v4.1.0/ParaViewCore/ServerManager/Default/vtkPVCameraCueManipulator.cxx, line 52
vtkPVCameraCueManipulator (0x8353f8e60): Too few keyframes to animate.

The python script:


# user defined variables, no identation allowed, start at col 1

infile  = "z.xdmf"  # name of XDMF file
picfile = "z.png"   # image output file
vidfile = "z.ogv"   # animation output file
trlo    = -4        # lower threshold
trhi    = 0         # upper threshold

# end of user variables
