Image Magic mpeg convert :
convert -delay 10 -alpha off *.jpg movie.mp4

-delay {time} Set the time delay (in 1/100th of a second) to pause after drawing the images that are read in or created after this setting has been defined.

You can specify a different scale for the time delay by specifying a 'x' scaling (giving in ticks per second). For example '10x1' is 10, 1 second ticks, while '10x100' is 10, one hundredth of a second ticks.

Basically the 'x' is equivalent to a fraction '/' sign. For example if you specify '1x160' will set a delay that is appropriate for 160 frames per second.
