I jumped in this thread to give a pointer. I’m not the moderator here and feel uncomfortable to take too much space here.
Here is another option to convert motion into keyframes:
With this, the series below will help with all kinds of converting problems:
… and there is the option to turn any spline into an animation path of course:
Motion Blur is not a natural given effect in Cinema 4D, it is set or not. Perhaps I misunderstand the idea of “…have a look at this animation…” as I’m not a coder of these wonderful tools. So toss anything of the following if I went into the wrong direction.
However, as an animator, you will write your own rules and create your own aesthetic. In art, there is no right and wrong, as long as you follow your vision. I’m not interested in tinting your work with my ideas, nor should that be anything like a critique. I would like always to caution about critic that is given without asking about any artistic intentions.
Having said that, classic stop motion works based on skipping one frame, to save time, as it cuts the filming (not the production) time nearly in half. We have seen that cinematography went from something around 18 frames per second to a standard of 24 fps at one point. The audience is catching up, not only based on better devices. So, some people film already in 60 fps and go from there. It is a more extended discussion and touches the artist’s intention very carefully, as mentioned before.
In 3d we have key-position, as it is widely known, and with that an interpolation of those, pretty much for free (compared to stop motion). I mention this, as I got a question during a presentation from a Stop motion artist, about this.
Anyway, as your question about the plugin indicated, the intention here is to destroy the interpolation towards a step by step “motion”. Which in return must be based on your intention, what do you want to achieve with it?
A real classic stop motion, emphasis on the stop, has no motion blur. Going by classic art 1on1, using a scene with motion blur and mix it with no motion blur elements creates a contrast. Contrast is always a way to make something more precise, in other words, to stand out. In return, this becomes an expression or if strong enough a statement. Which is again, something you have to mention while asking. Otherwise, you get opinions and those mostly based on taste. Taste is not the source of an artist, it is a tool of an artist; Intention is the source.
So, what do you really want to have in your animation? Then I can tell perhaps what to do. Otherwise, and that is what I have learned in my exhibitions and screening of my movies, often critic is only the action of avoidance to confront oneself with the impact of art, and this results in a request to the artist to change things up until it is smooth and effortless to digest. While the art has faded away in the process of such.
As mentioned, I answer in the Q&A forum (not typically here), but I do not criticize nor critique work in Cineversity, I support such work in any artistic way possible, inside of the possibilities of Cinema 4D.
Do what you love and push it as much as possible to become what you had envisioned. If there is an obstacle with the technique or tools, please ask in the Q&A forum. My best wishes for your project.
