I only wrote snap! because we don’t know how long it takes for output to
be produced by command line tools.  Not everything is instantaneous.
A regularly timed snap! was supposed to capture intermediate output such
as progress bars.

Are you saying you want to take snapshots in larger intervals and pad
the intermediate frames with duplicates of previous frames?
