I can not save an animation of my simulation. I am using ParaView 5.4.1 64 bit on Ubuntu with an NVIDIA GT430 graphics card: I get the following warnings and errors:

Do not use the avi writer in ParaView. It produce low quality high size frames.
I would recommend using the png writer to save your animation and then use ffmpeg to create your video.

Hi! I am trying to save my animation too and realized the same problem. The quality is not that great.

Could you further explain how one can use the png writer to export vtu files into png files?

Thanks!

ParaView 5.9 and 5.8 should now produce directly good quality avi.

In any case, here is how to generate avi from png:

Thank you it worked!
