Oh look, Dr. Pepper.
A Kamimemo is fine too.
You’ve messed up your frame rate.
Please recheck. It should be 24000/1001 -> 23.9760239760…. not 23.977.
in mkvmere header editor the default duration should be 1000000000/(24000/1001) -> 41708332 not 41706593.
That is clearly Mr. Pepper, Dr. Pepper’s younger brother who never made anything out of himself.
