[Paraview] saving animations from python

[Adriano Gagliardi]

Hi Blaise,

Here is some example code that should help:

#ensure you have cue and the keyframes already setup

    movie = servermanager.animation.AnimationScene()
    movie.ViewModules = [GetActiveView()]
    movie.NumberOfFrames = 10
    movie.Cues = [cue]

    movie_writer = servermanager.vtkSMAnimationSceneImageWriter()
    movie_writer.SetFileName("slice_movie.avi")
    movie_writer.SetFrameRate(2)
    movie_writer.SetQuality(2)
    #movie_writer.SetMagnification(2)
    movie_writer.SetAnimationScene(movie.SMProxy)
    movie_writer.Save()

If you want more information on each of these, open up the Python Shell and
take a look at the available functions.

Cheers,

Adriano

Subject: [Paraview] saving animations from python

Hi,

I am trying to script still frames and movie animations (time evolution) in
python. The goal is to do batch processing of a large number of simulations.

Parsing through the online documentation and wiki, I was able to do basic
movie files using the AnimateReader function, but I can't figure out how to
control the properties of the movie (number of frames, number of frames per
second etc). Trace does not return anything useful when using File -> Save
Animation. in the GUI.
   - Is it possible to set the options from the File -> Save Animation menu
programmatically in python?

I also looked into using keyframes for the time evolution, following the 3rd
example at
file:///opt/HPC/ParaView-3.10.1/Documentation/Book/Book_Chapter14.html#Anima
ting but still have issues: 
   - How do I set the cue in a keyframe to be the analysis time / time step
number?
   - Is it possible to programmatically save an animation to an avi file in
python?

Regards,

Blaise
