All the frame rates were synced at 29.97.
I used many codecs but my final attempt was the NTSC 48hz (I’m pretty sure that sounds right).
I’ve worked around it and have achieved my desired result.

I believe the root of the problem was in the speed ramp.
We’ll see in the upcoming clips (minus the ramp) if the problem persists.
Thank you both for your help.
much appreciated!
