Tool for splicing asciinema clips together?

Hi Asciinema community —

I’m curious whether anyone has a tool or script that can splice asciinema clips together? I understand that I can use the rec --append option to extend an existing clip with a new recording. But for the movie I’m trying to make, such a tool would make it easier to create a number of short clips and then to splice them together in arbitrary orders, or to later replace an intermediate clip without having to re-record all the clips that follow it.

Thanks for any pointers,

For anyone curious about this question, I believe my team has now developed such a script. I’ll post once I get more experience with it and permission from the author to do so.
