Hi Laura,

I can do the coarse adjustment on that one, to set the overall duration
and make sure that the audio streams are not truncated.

Could you re-build the other videos and check the internal timings? 
This is the fine adjustment that synchronizes the audio with the
command line output.  

I have briefly checked that this is sensible but there could be
improvements to be made.  The overall duration should stay the same. 
So if you remove 1000 ms of sleep from one section, for example, it
needs to be added back in elsewhere.

Best regards,

Paul.
