Thanks for the additional clarification, Remo_G. Yes, MoGraph Tracer as the producer, I understand.
Perhaps Main Menu>Mesh> Spline> Spline Smooth, might be a good choice here. Especially for straight parts.
A per frame setting is certainly dense, you make of course the artistic judgement call what is needed.
As long as no other option given, perhaps you could define groups for the “final” particle, and set up several Tracer. (But we go already into a Q&A discussion here: let’s wait what the producer of this plug in have to say.)
It seems this year closes with this movie clip, which is number 116 for this year:
It is an option to get all the Tracer spline information to Illustrator, based on the camera view.
If you set the interpolation to something “smoother”, e.g., Cubic, it will show in Ai.
My best wishes and Happy NEW Year
