Hi Carl,

I am very beginner to ffmpeg. I usually get the commands from the browsing
from online blogs. I don't know how to set those options clearly. Could you
send me an example to use this pts and prev_pts options in the command? 

Also I tried the below command to  extract.

ffmpeg -i INPUT.ts -vf "select=not(mod(n\,25))" -vsync vfr -q:v 2

The above command is also not working, as it is extracting the more number
of frames.
