please translate your question in english

Nice idea, could you share it on our gitlab that it can be more easily tracked ?

Interesting idea. Would you mind sharing it on our discourse ?
https://discourse.paraview.org/

There is the progress bar updating if I'm not mistaken. Also I suggest using pvpython for any actual serious animation export.

That would requires to render two times more frames. Not sure this is a good idea.

not sure this is ParaView job to support this. Nonetheless you can open an issue to ask for this feature here : https://gitlab.kitware.com/paraview/paraview/issues

This is a very big endeavor this is being discussed here :
https://discourse.paraview.org/t/paraview-translation-discussion/2223

https://gitlab.kitware.com/paraview/paraview/issues/19291#note_620241
After discussion, it as deemed unnecessary.

looks like you already put this in gitlab :)

That's a good idea and should not be too hard to implement. Feel free to open on issue on our gitlab :
https://gitlab.kitware.com/paraview/paraview/issues

Which format are you referring to ?

Please post on our gitlab to track the issue.

That would indeed be nice.

May I suggest using the gltf exporter instead ?

This is a nice idea, you may want to open an issue on https://gitlab.kitware.com/paraview/paraview/issues for more visibility

This may come into ParaView in a few months

OpenDx being discontinued, I doubt anyone will work on that. If you can run OpenDx can you export the file to another format ?

You can save as ensight in Ansys and then read the file in ParaView

This is a nice idea and should not be too hard to implement. You may want to open an issue for this feature on our gitlab: gitlab.kitware.com/paraview/paraview

You can use transform as a work around.

Already supported trough qt5ct :

(Weren't you the one asking on discourse?)
