The single most important question is:
What do you mean with "convert"?

Usually, changing the speed of the video is completely
unacceptable, but if it is acceptable for you, you can
test the input option "-r" which (is different from the
output option "-r" and) allows you to save the intermediate
step to change the speed (and duration) of the output
file (but does not always work, please test).

Please provide an input sample file to allow debugging
of the bands you see with the framerate filter.

Generally, please always post the command lines
you tested together with the complete, uncut console
