it's not as hard as you're making it seem, you just allow for a positive or negative time offset and rely on the devices counting seconds similarly, which is mostly a given now.

I did this with raw footage and a VESC speed controller dump to overlay a bunch of motor stats on a prior project, this was pre-AI and it was still only an afternoon project.

ffmpeg/image-magick do all the real heavy lifting out of the box.
