When you click and see the actual preset (twearling down all the arrows), you can see someone animated the characters for you. That is preset. You can actually modify that animation and save the new file into preset library.
For the jumpy issue,
You can try giving different influence to each character (30%, 70% etc.)
If I were you, before going into headache, I’ll try motion blur for everything and if that helps, you are done.
I hope this helps.
