Hi,
why is the framerate automatically changed here from 29.98 fps to 120 fps, and
how can I prevent from this ?

You can add `-fpsmax 30` with v4.4 or newer. This will limit output rate to 30
if the input is higher else keep the original rate.
With that I get a rate of 30 instead of the original 29.98, so each 50th frame
gets duplicated, which I value as nonse

I guess you could use the -r option to override this and force a
specific framerate if you want something different?
Yes, this works fine. But I would appreciate, if I could use something like
-r=inputrate or --keep_framerate
I've found out, that using
