I think '-framerate 60' may not be needed at all.
It is only needed if 60fps recording is wanted.
As said before, setpts should generally be avoided and
this is even more true for settb.
Serious questions:
'setpts=N/FR/TB' seems to be reliable, and is the only way I've gotten some of my frame gymnastics
to work. What is wrong/dangerous about 'setpts"?
Note: I'm aware that frames can be out-of-order for some input streams (e.g. mpeg2video) but they
seem to be in-order in the frame pipeline. Is there some reason to *not* take advantage of that?
'settb=expr=1/720000' seems to be pretty useful for improving the timing resolution of the filter
pipeline. Why do you think it should be avoided?
Regards, and Much Thanks,
Mark.
