unable to trim start: failure to transform cast

[rnag]

I unable to get asciinema-edit (v0.0.6) to work on a Mac OS environment - can provide more details if needed.

cat ~/Downloads/483363.cast | \
      asciinema-edit cut \ 
         --start=0.0 --end=5.0

The error shows is failed to transform cast: couldn't find initial frame. wasn't sure if I'm doing something wrong on my end.

Getting same error, also happens if I just drop --start and only use --end, not the behavior I would expect.

What does work is finding the exact timestamps of certain frames and using them.
