Thanks! That looks useful.
I decided to insert the start time and the end time; I can then let the web
page display the duration.
When you say "If you need to do that inside motion" I think you're suggesting
forking the code? I was saving that for a last resort, but might consider it.

%q is frame number of one second, ex, if your fps is 5, you will have frames
numbers 1,2,3,4 and 5 every second The only reliable way to get the length of a
movie is to run a script with mediainfo command on_movie_end, example:
mediainfo 20190208-0750-207.mp4 | grep Duration | head -n 1 | awk '{ print $3
$4 }'
But if you need to do that inside motion, you should count all frames send to
the movie encoder and then calculate: TOTAL_FRAMES_SENT / FPS = SECONDS
