Thanks, that seems like a workable approach.

As a result of 5 minutes experimenting, I would add these notes:

 not all input formats allow -ss

 -endpos is a duration parm, ie, relative to ss starting point (if any)

 the ".ms" part is, I guess, is supposed to indicate that the seconds
part allows a decimal part. .5 is 1/2 second not 5ms <heh>.
