All I can tell you is I don't experience the same problem and I had a
smooth transition when playing back with mplayer or vlc.

If this is with motion clips I'd be interested in your config. I've
tried a few different things but I probably haven't explored all the
options/combinations. Perhaps it needs a low manual frame rate, or I
have misconfigured something. Perhaps it's connected with webcam type
too. My tests have been with the camera module - I may try using output
from a USB webcam.

Yeah, your example video is weird. I have always used extpipe with
motion to avoid any variable bitrate or especially variable frame
rate.
Can you try disabling duplication of frames? Does it change anything?
Also, give extpipe a try, maybe that would suite your needs?

I just installed a new Rpi4 with Raspbian 12 bookworm
https://motion-project.github.io/motionplus_build.html
says that one culd install the premade packages
I Only see a bookwork package for amd64, not arm64
and installing the bullseye package
bullseye_motionplus_0.1.1-1_arm64_202308.deb
runs into missing dependencies:

Is there a workaround? oir should I downgrade to Bullseye (or use motion
instead)?
