[General] Scripting: Framerate when saving animation...

MarkHerskind · January 3, 2019, 09:58

Hi..

I'm making a script to automatically save an animation from Paraview..
The simulation is 20sec and in 0.1sec timesteps..
I would like to save the video with a framerate of 10, so that it will be in real-time..

When saving manually and tracing it works as it is supposed to, but the running pvbatch/pvpython the framerate is ignored, and the video is save in 1fps, which gives a play-time of 200secs (3min 20secs) instead...

Code:

SaveAnimation('/data/gompute/home/74682/OF-Cases/test_3/output/alpha.avi', renderView1, ImageResolution=[2000, 848], FrameRate=10, FrameWindow=[0, 200])

Any ideas why this doesn't work?

I'm working in Paraview 5.6.0-RC3 64bit in Linux...

Thanks!
Mark

When dealing with animations in Paraview -or any other software for that matter- I export images instead of video files. Then you can use e.g. FFMPEG to get the exact animation you want.
Not exactly the solution to your question, but a solution that works 100% of the time and gives you more flexibility.
