Honestly the first problem is you are using Ray Traced in the computer I would recommend Cinema4D For text editing but just decrease the font size and mess with the properties to make it less chunky sorry if I wasnt that helpful don't have much experience with ray-traced

Well First thing dont use the camera tracker for text it looks gross there is not really a fix if your looking for 3d text use cinema 4d r16 has a built in motion tracked just render the clip in tiff sequence then import the sequence as a texture apply to a background if your using another version thats not r16 then you will need to motion track in boujou just render as tiff and import as same fps then export as C4D and open it in cinema 4d or you could get element 3d and camera track it in after effects and make a solid then apply the element 3d and make a white text saying what you want then goto layer and auto trace it then turn off the opacity of the text and then layer auto trace goto element custom mask and select the trace layer go into element 3d and click extrude and your good to go sorry for no gramer or anything im lazy and this was a lot to write good luck any questions msg me on here
