RTSP "generates lots of artifacts" and RTMP "have frame repeats and missing
segments" sounds as pretty much the same
Could you please set up your cameras as RTSP, run the same test once again
and reupload the motion.log?

And do you really need 1000 FPS in your config?
# Maximum number of frames to be captured per second.
framerate 1000
I'd suggest to specify the real framerate here
