No, showinfo reports 11880, 24120, 36000 because that's what the input video's frame times are.
The input video does not have constant frame time increments (so the evidence indicates).
Yes, I now understand that 'settb' doesn't create new PTSs, it just takes the times and rescales
them to the new time base. For that, I give you thanks.
"16.18 settb, asettb
"Set the timebase to use for the output frames timestamps. It is mainly useful for testing timebase
configuration.
"It accepts the following parameters:
"expr, tb
" The expression which is evaluated into the output timebase.
"The value for tb is an arithmetic expression representing a rational. The expression can contain
the constants "AVTB" (the default timebase), "intb" (the input timebase) and "sr" (the sample rate,
audio only). Default value is "intb". "
That documentation doesn't say that, even if the argument is *not* 'intb', the input's time base is
nonetheless used to rescale the input's PTSs. My bad.
I will try 'settb=expr=1/360000,setpts=N*1001/30000*360000,fps=30000/1001'.
Regards, and Thanks Again,
Mark.
