I've download your video. Thank you.
In my case SVP changed smooth coefficient from 2x to 2,5x in 7 seconds after end of opening.
mkv2vfr output:
# timecode format v1
Assume 23.976
0,790,29.9701
791,791,20.4082
792,3714,23.9759
So, from frame 0 to frame 790 video has 29,9701 fps and from frame 792 to frame 3714 video has 23.9759 fps.
And we can calculate the moment of framerate switching from one fps to another.
It is 791 / 29.9701 = 26,4 sec
