Hi Paul!

> This plays at the right speed for me in Videos/Totem (version 3.26).
Don't know what happened. I deleted all the videos and made them again
and now I don't see that issue anymore.

For this, what I could do is generate the cli sesison video with the
"silence1.mp3" to have duration1, and then compare it with the
duration of cli1.mp3 (for instance).  Then, run a script comparing the
durations while duration2 < duration1 append silence1.mp3 to cli1.mp3.
And finally use the generated cli1.mp3 as the input matching the video
stream.
I find a little bit manual, but I don't mind doing it if you find it OK.
WDYT?

Regards :)
